Hi, Jo from Germany here. I love your show! As far as measurements are concerned, in situations like this we use only millimeters, for example we say "you need to cut off 38 mm". 1 mm equals 0.039 inches which is already quite small, but it's quite frequent to divide the mm in its decimals ("1.2 mm").
And in fabrication 1mm is almost every time small enough. I mean how often do you need something more precise the e.g. 3 13/16 inches. For machining we of course use 1 or 2 (or even more) decimals.
Mac from Canada here, we do the same here as Jo from Germany, the only time I have heard anyone use decimeters was a road builder and he would say stuff like " We need to bring it up 3 decks here and cut it down 2.3 decks over there, so just use that fill from over there to build this up here!" BUT I have never heard any other crew use decimeters that way.
I used to be a science teacher in the mid 1970s and I would teach the kids about the metric system and demanded they use it. There was the usual whining, but I gave them 2 quizzes. The first one was a quiz on the English system, it drove them crazy. For example: How many feet in a mile? How many inches in a yard? How many ounces in a cup. How many ounces in a pound. How many pints in a quart? How many quarts in a gallon? You get the idea, they didn’t know most of the answers. Then I gave them a quiz on the metric system. I constructed the quiz so that every answer was 10. For example: How many millimeters in a centimeter (10). How many centimeters in a decimeter (10). How many decimeters in a meter? (10). How many decimeter is in a Kilometer (10) How many grams in a centigram? (10) How many centigrams in a gram?(10) How many grams in a a decigram (10). How many decigrams are in a kilogram?(10) if you know these, how many milligrams in a kilogram? (1000- 10 x 10 x 10) same goes for all the rest. It was then the kids realized the metric system is just a series of multiplying or divided by 10 it’s easy! Then I showed them the easy method of just moving the decimal point. For example How many centimeters in 205 millimeters. 205/10 is 20.5 centimeters. See it’s easy! I showed them the DRUL rule. From biggest (Kilometer to millimeter) from top to bottom, largest to smallest. The DRUL shows that as you go down you move the decimal to the right (Down Right), if you move up, How many millimeters in a Kilometer you move the decimal to the left (Up Left). Eventually I convinced most of the students that the decimal system makes much better logic. Everybody can multiply and divide by 10. Hopefully! Hey Matt and Tom, you too can be comfortable with the metric system. It will require you to buy metric wrenches which I bet you already have. You too can master the metric system!
Can we just take a minute to appreciate Matts engineering skills, the man built the Morrvair and this wrecker from ideas in his head and brought them to real life, and they aren't show trucks built to look pretty they are purpose built machines ready to put in a lifetime of hard work.
👏🦾
And yet they do look quite pretty
@@jonahollstein verdade..👍👍
Banana too at one point
I went with 5000lb bags and I really wish I went with the 7500lb bags for just a little more money. What are Matts?
I love how Tom actually knows what he's doing and disapproves of many things/processes Matt does, and is almost equally happy and dissapointed when it seems to work out ok anyway.
For total measuring we use mm so you could measure 54.35mm using a digital caliper / micrometer. And if you ever get into precision engineering, we measure microns 0.001 of a millimetre with a digital micrometer etc.... Hope that gives some insight into the metric system, love the video's! Cant wait to see the wrecker up and running!
They introduced the metric system in canada in the 70s and it is so much more precise than standard. Unfortunately, the Americans and British are too stubborn to fall in line. Its like the language. Speak English or die. Wait a min. I've just made myself look like an ldiot.
its mm until that level of precision becomes unnessicary, so 50cm is 50cm but 500mm is that but more precise :)
@@JWbrasser It also comes down to application, You will measure the field in meters, your house when building in cm and anything technical in mm or m (not in cm), depending on scale context. Wheelbase of a car will be written down as 2800mm or 2,8m for example.
The absolute best person to have on your team is someone who cares enough to respectfully question your methods. I know it can cause friction, but if you can get that relationship to work out, it’s frickin’ gold. I think you guys are working together brilliantly. Tom Tom is awesome
I'm that respectful questioner.
I can confirm no one likes having that guy(me) around until he's not around!
This is truth!
Absolutely! Mat is a great hard-charger, go in and get it done. Tom-Tom is the perfect yes, but guy. It can suck being the yes but guy, however, sometimes a great leader needs equally great advisors.
@Yellow Ticket lol it generally always sucks being the yes, but guy!
The boss who surrounds himself with yes people is setting himself up to lose.
Chad needs an award at the Off-road Tow Truck Olympics because he seems to have wired everyone's truck.

I like Chad, easygoing and hard-working at the same time
He is the Edith Head of the off-road world.

HOLY Loc-tite dude!!! Just a tiny drop on those big threads is PLENTY! When I was in Manufacturing Engineering, we were going to use Loc-tite on something back in the early 1980s. They sent a rep to me to explain that less is more. He gave me some printed sheets with a picture of a Loc-tite bottle tipped with a drop on the tip and a huge pile of bolts and nuts with text below that said "1 drop holds all of this". They had me send those sheets to the manufacturing plants to be placed by where the Loc-tite was to be used. When a manufacturer says to use WAY less of their product, you know it's the real deal and NOT a sales ploy to sell more product. After that company downsized and laid me off along with 2/3 of the rest of the personnel, I started my race car and restoration company PREPCo. I built cars and trucks that won their categories in the Baja 1000, Championships in offroad and road racing and sprint cars, midgets and Super Modifieds. Using what I was taught about Loc-tite none of those cars ever had trouble with hardware coming loose. I'm retired for 7 years now. Just pulled apart an engine and trans from an offroad race truck the other day. The bellhousing bolt holes were filled solid around the bolt shanks with red Loc-tite. And the wasn't even in the thread area. There was more than enough Loc-tite wasted to have held the whole race truck together.
22:14 metric would all be said in mm mate. use cm for big stuff like doorways, and use mm for small precise stuff like the steering stops. So what you are making would be 54mm as you said. G'day from Tasmania, Australia long time subscriber of your channel and love all that you guys do.
would you use decimals for in between 1 and 2 mm? Like 1.5 mm?
@@armourbl yes
@@armourbl depending the accuracy, decimals up to 0.001 mm
@@armourbl keep in mind the 1mm is about 1/25 of a inch, so 0.5mm is close to 1/50 if a inch. When would you really ever need that accurate.
@@armourbl only if you it needed to be laser perfect. But 1mm is a very small 'american unit' . And if it's aay 1.6mm for some reason, just round up to 2mm
Hi Matt, a few years ago a friend of mine was using a grinder, the disk flew apart which claimed his sight, get all your team and yourself to put a blind fold on for 5 min just to see what it would be like never to see again, its not that hard to put safety glasses on, sorry to go on about this subject but you and the team are too valuable to loose, hope you read this, love your show. Robert.
Amen, Robert. I'm also Robert and it's killing me watching these guys take such chances. We don't even pick up a grinder where I work without a faceshield. It's a fact of life, and OSHA law for workplaces. Standing in the sparks looks cool on camera, but the only good thing is that the inevitable injury is going to be well documented.
PLEASE, M.O.R.R crew, get and wear eye protection. It's a terrible example and will be a painful lesson when it happens. Don't be statistics- we love you guys! --Robert
@@BikeNewLondon It should be mandatory for everyone in the shop to have safety glasses and hearing protection weather or not you are working on something or not. It should be "You don't enter without it". Matt is running a business and it is tough to watch with so many issues that are hazardous and creates huge liability issues. Even if Matt's Offroad Recovery Adventures is an LLC. But the one at risk of liability may not even be Matt. Who is Carrie Nielson
Hi Matt, love your videos. It is great to watch you guys recovering in the snow while I am sitting here in our comfortable summer weather!
Metric measurements: I often feel agony for you when you have to work in imperial measurements, that we drive me insane! In Australia, we only use metric, so here are some examples as to how we work. Up to 1m, we would only express the length in millimeters, so in your case, yes, it would be 54mm. We would say "54 mils". (I'm expressing that phonetically, if we were writing it down, it would obviously be 54mm) Once we go over 1m, say 3.540, some people will express that as "three point five four zero", some would say "thirty five hundred and forty". We never worry about breaking down 1mm, for 99% of us, that's small enough! I'm not certain, but I think someone working in engineering, say on a lathe, may still work in thousands of an inch. I could be wrong there, maybe they deal in thousands of a mm now?? When you are working on the mighty wrecker, if you got down to tolerances of 1mm, you would probably be okay! Can't wait to see the new wrecker at work! Bless you all 🙂
Some manufacturing practices confuse the issue. The thickness of some plastics or films may be expressed such as 6 mil poly but refers to thousandths of an inch. Boeing uses rulers that are graduated in tenths of an inch. Some lumber assembly may state 10.5 feet which is actually 10 feet 6 inches. Throw in a British pint vs a US pint and you can start to see why metric is used as a international unit. When the robots of the future overthrow us they can sort it all out. No worries!
If you need smaller than millimeters, you'd use micrometers, which are 1/1000, but fancier(and shorter) name
@@tilnation14 Commonly expressed as microns ;-)
I've been using Valvoline Wheel bearing grease for 50+ years. Another good grease is Boat outdrive blue spline grease. A little expensive but more water resistant in case seals fail. Hope the new hubs last a long time! Wrecker

I grew up in my dad’s garage, then went to school for mechanical design and learned the ‘right’ way to do things. To this day, one of my favorite things is all the ‘wrong’ ways my dad does things, and how well it always seems to work. What I’ve learned from all this is that there’s theory, and there’s practical application. Both are valuable, but at the end of the day, practical application always wins. If it’s stupid but it works, it ain’t stupid.
As for metric system…
3,256.3 millimeters
325.6 centimeters
3.3 meters
Instead of fractions (3-1/2mm), you use decimals (3.5mm). For example, instead of 3-7/8mm, you’d use 3.875mm. Since millimeters are much smaller than inches, I’d likely round it to a single decimal place and maintain accuracy, so 3.9mm. And so on. Just depends on how accurate you need to be for each measurement.
I prefer metric, my dad can’t wrap his mind around it. My argument is basically that it’s easier to add metric numbers than un-like fractions. I can do it, but it involves converting the fractions to like denominators and adding fractions. Using metric just saves that step.
Example:
3-1/4 + 3-7/8 ->
3-2/8 + 3-7/8 ->
6-9/8 ->
7-1/8
Or in metric:
3.250 + 3.875 ->
7.125
However, my dad’s just done fractions his entire life, so it’s automatic for him. He’s a much better mechanic and fabricator than me, so do what works for you, as long as it works.
I’ll also point out that it’s harder to find a metric tape measure, square, etc. They’re out there, just not nearly as common, so there’s that.
Clear as mud? 😂
Like stripping down an engine to get the heads off, do it by the book and it will take all morning but a few short cuts and half hour.
That was impressively thorough. Thank you. i agree on all points
Great explanation 👍
That’s nice and all But a car engineer will walk past 2 Virgins to screw a mechanic.
Danggg
It's great seeing the progress on the wrecker. And for measurements we wouldn't use fractions or swap units and instead just use additional decimal places depending on what suits the scale of the part.
So its not 13cm and 2.5mm, or 13cm and 1/4, but it could be either 13.25cm, or 132.5mm. It's definitely a lot easier to work with, especially at small scale
It is always crazy when using multiple measuring standards at the same time.
Correct except, in the UK, centimetres are not often used-rather like Americans rarely use yards. We might even use millimetres for the length of the vehicle: for example 4568mm-which is 4 metres, and 568 millimetres. For less than a mm we use microns which are 1000th of a mm or a millionth of a metre. There are no fractions in the metric system.
We are also very familiar with conversion to imperial. For example 25mm is an about an inch, 150mm is 6 inches and 300mm is about a foot.
@@johnrussell5245 BS. Unless you are into imperial measurements for one reason or another (ike into aviation) most stuff is in metric. Most engineering is done in metric and other than old guys in a shed, you'll get almost shot for trying to do anything in imperial.
Well in Utah they don't measure anything, they mayzure.
@@AJNpa80 then drive through the crick, and up into the mou'uns.
Hi Matt, yes in Canada we still use the imperial system for some measurements. We do not use deci or deca meters in normal environments. Using millimeters versus centimeters really depends on the accuracy of the measurements you are about to make. We do use have portions (i.e. 2.5cm) but rarely other fractions, we would normally go to the smaller units (25mm or 250 micrometers). Hope this helps
25 millimeters is actually 25000 micrometers. And yes, i know in Canada we're supposed to spell it "millimetres" but it always looks "wrong" to me. Yet micrometer is correct, and micrometre is incorrect. 😂
To answer you question Matt, you would use (up to) w decimal places when you're measuring for applications like building WLORW. As a precision grinding specialist (hey, i don't make up my job title, LOL!) i use 3 decimal places - which takes you into the realm of microns. To put that into the physical world that most people understand, the human hair is 0.003" in Ø. That equates to 0.0762mm. Hope that helps you better understand the crazy metric world.
Dude! Matt please throw this rig on a scale when you are 100% complete. So interested to see final weight.
You are all so awesome, love the vids everyone
Our measurements are usually given in one unit because they are always multiples of 10, so you can easily divide them in your head. For example, you might say 1050.5 mm, which would otherwise be 1m, 5cm and half a millimetre. In Germany at least, tyres are measured in metric, only rims are measured in inches. P.s. Love your videos, Matt and crew
This!! It amuses me why people from the US think it’s so hard. Just use millimeters (mills). No weird fractions needed. You can build the whole off road wrecker using one unit of measurement. No having to add 15/16ths to 5/8ths ever again! (I couldn’t do that anyway)
Tires, mate❣️🚙😎
Yeah, it just takes a bit of practice and getting used to the units.
correct, using the metric system it virtually doesn't matter if you say 1.0505 m, 105.05 cm or 1050.5 mm.
To increase accuracy just ad digits, if you want "3 and 1/4 of a milimeter" (noone would say that) its 3.25mm
Thats for your understanding, we don't use fractions.
Thats usually what confuses metric-thinking people about the imperial system and makes it so complicated for them.
How you would say 3.37 inches in fractions, I have no clue.
It amuses me why people who use the metric system thing fractions are so hard. It’s what ever your use to using. Why re-learn another attempt when it’s not necessary.
Always go mm unless you need less accuracy than a cm. So your wheelbase might be 3850mm. Concidering a mm is way less than 1/16", they usually don't need to be split unless talking clearances, then you usually use a decimal and 10ths, 100ths and 1000ths. Been working on Japanese bikes for decades...
Metric system is simply better. No conversion shenanigans needed. It just works.
This, we even use mm in shipbuilding. it does give us big numbers sometimes.
But we either use mm or m. rarely anything in between.
For example a propshaft might be 200.00mm (the zero's added to give an imediate idea of accuracy without checking the drawing)
Or a ship might be 120.15m long
The irony is for really accurate imperial measurements it uses a non-fractional base ten system…just like metric. A fraction is just an awkward way of expressing a decimal.
Instead of 3850mm why not just say 3.85m? lol
@@SuperAWaC it is for precision as stated above, and also so that all measurements on the plans are the same. In construction we see all our heights as mm, so say on a plan you will see 400mm for one thing and distance between 2 things being 3500mm. once you start getting to things that need less precision or are on a bigger scale we will see meters come out
Ed looks great, he is always interested in what is happening and he is always included
grdhjrdjr123
Love watching you guys!! Awesome build so far!
To answer the metric question, we (in England) use the metric decimal system so we don't use fractions. We use the decimal equivalent. Everything thing is based on the millimeter (mm)
1 inch = 25.4mm
1 1/16 = 26.9875mm (round up and say 27mm)
With very accurate measurements, it's still based on the millimeter
1 micron = 0.001mm
If you're measuring something big, you would move the decimal point.
2.5 meters = 2500mm you would just say 2 and a half meters .
Usually I'd never measure any more detail than to a whole millimeter, but if you're machining something precise then most calipers go down to 0.1 or 0.01 millimeters.
But we don't go into fractions like 1/4 or 5/16. It's always decimal based.
Edit: what Tom Tom said is pretty much correct, no decimeters and usually not centimeters if you're blue collar.
For the metric system, generally up in the great white north, we either use MM for small measurements, and normally CM with a decimal for larger measurements. So something that's 325mm, would be 32.5cm. Great work guys, the wrecker is really shaping up. It's was always fun doing shop work with my dad, because he's an old school machinist, and everything for him has always been imperial measurements, but everything for me in school was metric. So it took a while for me for me to get used to imperial, but for some reason a lot of the trades still use it for everything, construction is one, you never see guys using metric for that up here. Honestly, its kind of annoying.
Australia goes straight from decimals of a mil to millimetres to metres, and then kilometres! The only ones i have encountered who know what centimetres are, are dressmakers and upholsterers. The beauty of the whole system is that one litre of water measures 100 x 100x100 millimetres, and weighs exactly one kilogram!
Milimeters is for engineering, centimeters is for carpenters; that what we told in my country
@@grahamcifuentes4451 that's a good point actually I forgot how little I use cm
@@carlosdelcastillo1513 as a carpenter we use millimetres exclusively to avoid apprentice errors! Machinists use millimetres, hundredths of a millimetre and thousands of a millimetre. No need for thirty-seconds of an inch!
It's more about precision, we may use centimeters here for stuff that require .1cm precision, millimeters for .1mm precision, meters for .1m
In France at least we say for a house like 12meters and 59centimeters, but for a plank we might as well use 240cm as 2meter 40centimeters. But 240 is prefered because it makes more sense as a unit in this case.
For tiny amounts, I'm not a machinist so I don't know.
The conversion is really easy anyway from meters to centimeters to millimeters.
Also averagely a rule of thumbs, I would say for each unit you wouldn't use too large a number. Maybe for the precision.
Specific rule for plans : They have the same unit. House is I think centimeters ? Bananas are in centimeters, most tools also.
For heavy duty automotive and equipment lubricant grease hands down the best I have ever used in my 40 years as a mechanic is Chevron Ultra Duty Grease EP (extreme pressure). Very good for packing wheel bearings. Plus it’s red for Tom Tom!
"Kind of like pliers. We did a little bit of everything, but nothing really well." Words to live by!
I always use MM up to hundreds of MM. It's not uncommon to see 235mm, for example. Once you start using it, it's a heck of a lot easier, quicker, and less prone to mistake on markings. And it's a lot easier to divide up and multiply.
I build bridges and everything is in mm, 15'000 mm long ballast walls etc. We also just use both systems 16ft 2x4s cut out pieces in feet and inches etc but just also use mm 🤷♂️
Like we are pile driving right now im putting two 65ft piles in but they get welded together and i know the splice is at 18'200mm a.k.a 18 meters 200mm lol
Absolutely. I do cabinetry and I find it far easier to use metric. In addition to being able to use straight mm you can say something like 2.2 cm and it’s easy to convert to mm because it’s a base ten system. 22mm
@jessepitt Ditto!!!!! The problem for most people before they use it, is the we have a pretty good idea of what an inch, 8 inches, or a foot is, but no good idea how much 2.54 cm, 20cm, or 30.5cm is..... so it's easier to go with what one knows.....but i totally want to say that it's worth the change!!!!
Adding to the anti-metric silliness is the same people that complain about the metric system also complain about using fractions. But the prefer a system that relies on fractions?
For metric you wouldn’t use fractions the same way most folks do with imperial measurements. A mm is 1/25th of an inch which may be good enough. If you need finer accuracy you use decimals, 12.84 mm for example. The arithmetic is much easier because everything is in decimals. You can get imperial measuring tools that measure with decimals (I have a combination square marked every 0.05”). Then the arithmetic would be the same imperial or metric. Haven’t seen a tape measure with decimals yet though.
Chad's wife: "Wire that alarm to the gas gauge!".
Matt: " I wouldn't want to listen to *that* all the time!".
Matt: Working as a professional mechanic here in the US, our shop switched to metric for those kind of measurements, specifically for alignments, because we had higher accuracy and fewer misunderstandings. We read out the measurements in whole millimeters. So if we were measuring toe, the front of tire measurement might be 2165 and the rear of tire measurement might be 2166 and everyone would be clear that the car had 1mm of toe in. Similar measurements would be made for front thrust compared to the rear axle. With this, it was REALLY easy to know how much you needed to adjust the tie rods to correct total toe AND which tie rod needed the majority of the adjustment to fix thrust at the same time. With nice round numbers, no fractions, being called out everyone stayed on the same page and there was no confusion.
The idea is to keep big, simple numbers by always using millimeters so there was never any confusion about what the units were. Also pays off big time when you want to divide something into equal parts, figure out a center point, figure out the length of the long side of a triangle, etc because a lot of the shop could get close enough in their heads and EVERYONE could do it with the calculator app on their phone, unlike using fractional inches.
On most car-related stuff, whole millimeters are fine when you consider that a millimeter is 1/25th of an inch. Unless you're often working to 1/64 of an inch or better tolerance now, you can stick to whole millimeters. When you're fabricating something that you're going to measure with a micrometer, or at least a caliper, then you get into tenths of a millimeter and might call for something to be made 150.7mm long. Outside of a lab or aerospace, you'll never get down to the hundredth of a millimeter because that's such a god awfully tiny unit.
Im an engineer who uses metric at times.
I usually use just mm & meter, with using decimals on the mm even though there are finer measurements.
If its something ultrafine you step down another 1000 to micrometers. The fact that there is a unit every 10 is nice but usually moving in 10^3 suits me best for units of length
In Australia the engineering I've been around stay using mm's no matter how small, we don't go to microns. If it need that much precision we would say 23.589mm instead of 23589 microns.
I challenge Matt to use mm for a week.
@@Ev.FromMars 23mm is still way too large to use microns. I'm an engineer in the US and we use microns when talking about things that are less than ~0.1mm.
We all need someone like Tom Tom in our lives making sure we stop delaying fixing broken things and do it the right way.
Turning the shocks around was such a DOH moment. Simple solution.
People would bring their car in to my dad after getting tires put on at another shop. The other shop tightened so tight, they wouldn't come off. My dad would send them back to that shop and they would sometimes break them off. They never learned!
I already am that guy. I need someone that helps me just do things and not worry about perfection lol

Is that called a wife??
Tom Tom is a really good addition to your team and at least should get the award for employee of the week award for helping on everything hes asked to . Smiles 😃 from Canada 🇨🇦
He's way too anal and he sometimes disrespect Matt. He is lucky Matt is a gentleman.
and i think he's the voice of reason.
Automotive OEM experience. Millimeters is the standard "inch" measurement. So all numbers are 2 3/16 would be 55.55 mm or gnat's knees would be 55.549 mm which would be an accuracy 2.1875 inches. Far more information than hand drill, bit or grinder will ever need. Really enjoy the build.
Tomtom, you have been my hero in so many ways. Where are your safety glasses when you are drilling and grinding on the rock slides??
It's nice to see it coming together. I saw you jumped pretty quick with the spark show.
Metric measurements. As a machinist, the metric prints come out using millimeter ( mm ). They can go into the thousands When you get a partial mm, they use a decimal point. As in, 1 inch equals 25.4 mm
You could do either 52mm, or 5.2cm. In my workshop it’s usually called out in millimetres unless stated otherwise, e.g. “cut this down to 52”. For smaller measurements you use decimals on the millimeters, or go to a smaller unit.
Good thing about metric is it's base-ten. So "five point two cm" is the same as "fifty two mm."
Agreed most people would do mm until a very large measurement when you go to cm
In calling out metric measures, it often depends on scale and accuracy. Less than a meter, the measure would be in mm. Less than 100mm the accuracy would be +/- 0.2mm. Less than 20mm, accuracy would be +/- 0.1mm. Greater than 1m +/- 1mm . Nobody uses cm or dm!
There are two kinds of countries in the world…. Those who use the metric system and those who have put man on the moon.
@@JettaJack I use cm occasionally. Bicycle industry uses cm for certain frame sizes, so it is out there in some industries. That said, I also prefer keeping it to millimeters and meters whenever possible.
Seeing this wrecker in action will be awesome! The work that has been done is amazing! Matt and crew, good job!
I absolutely love how quickly Matt moves from 0 to 60 when sparks start raining down from heaven. He went from Zero to 60 in 0.03 seconds, and then immediately back to Zero once he found the source of the problem. "We're gonna need a new one of these". Hilarious!
Due to the metric system being divided into tenths, you would usually choose the unit that best represents the objects length, for example i would say that bolt is 23 millimeters long (ca. 1 inch), a saw blade is a 15 centimeters (ca.6 inches) in diameter, while a bridge is 45 meters long (ca.147 feet). A rule of thumb that I use is that if a length has more than three numbers, like 3654 mm, and is not in meters I change the unit, so in the previous example it would be 365.4 cm. But you should always choose the unit that makes the most sense in your application.
If you need measurements smaller than millimeters you do it with decimals, ex. 0.1875 mm, rather than 3/16 mm. If the measurement is 2.5 mm I would say "2 and a half", but "2 point 5" works just as well and is perceived as a bit more exact in some cases.
Awesome, thanks for that!
couldn´t have said it better myself!
Also most tires are measured in both inch's and mm, large mudders usually being the exception. 235 40 R18 is 235mm 18 is inches. Something to do with DOT regulations on rim size.
Expertly explained.
Half way through, I just realized I'm dumb.. 🙂 but seriously best argument I've seen for using the metric
Hi Matt! About the metric system (22:30). First of all, you don't usually mix mm, cm, dm and m. What you do is that you kind of adapt to what's convenient. We don't really think in fractions, we replace fractions with decimals, this is the most important part. You may know that [mm = m/1000 ], [cm = m/100] , [dm = m/10], so you could easily just mention something in meters, but still specifying the millimeters like 1,003m. Or more conveniently 1003mm. Say something is a third of a centimeter, then that's approximately 0,33cm or 3,33 mm. You can absolutely fraction sometimes, if it is convenient. So I for instance could say that something is (54,23mm)="fifty four point twenty three" mm, or (55,5mm) "fifty five point five" or alternatively "fifty five and a half". Fractions are not really needed at all when you use decimals thought, as with decimals, each "step" gives you more precision, and since you usually don't go more precise than measurements in whole millimeters, most things done in your garage would easily be counted in whole millimeters like 194mm. Or if that's easier, the same length could be described as 19,4cm if that's easier. And a bonus joke: Four Thirds of all Americans struggle with fractions.
+ Oh, and that's right about decimeters, no one really uses them. Thought it's cool that a box of 1 cubic decimeter equals exactly 1 litre!
And yes, some things are standard in inches, even here. Rim diameter is one thing that's still always measured in inches, also the connections for sockets, like 1/4" and some other weird things. You should try the metric system some time, it's not too bad! (Please add the temperatures in C* too as you sometimes did, I google it everytime!). Keep up the great work, the work you do, all of you, is amazing. Wish you luck for the upcoming tournament, from Sweden!
YOU MUST BE A TEACHER!!! Spit it out!!! WTF MAN
Will second the OP from a Canadian perspective, although we’re bi-lingual here, regularly bouncing between Metric and SAE/Imperial thanks to the influence from our southern neighbours. MM is the typical measurement reference in construction or fabrication North of the Border. Metric makes a lot of sense when you get used to it. Super handy for volume measurements as well.
@@THE1THEONLYBODACIOUS no the guy just knows his stuff! Don’t be jealous, learn it for your own benefit.
Using both metric and sae we generally prefer metric for the most part but my brain thinks in terms of fractions, usually a third or quarter so base 12 like the clock makes my head feel better.
Technically all decimals are already fractions just with a base 10 system 0.1=1/10th, 0.01=1/100th, 0.001=1/1000th, etch
I always appreciate that when you change something on the WLORW, or anything else you are working on, you take the time to tell us why and let us watch. The fact that you are always trying to improve on your own designs is a true mark of a craftsman. Well done to your entire crew! As always, God bless and be safe.
Improving on the design is always a plus no doubt. Sometimes its easier to see when its in front of you rather than in your head or on a blueprint.
I will say though it can cause havok as well. You can get caught in a viscous circle. A couple of my builds started with ideas that later have to be scraped due to changes or ideas that came up as I was fabricating.
Built my YJ up most of the way with 1/2 ton axles. Then seriously modified the suspension to the point that the required tire size was going to be too big for a half ton axle. Even with chromoly shafts and stronger joints.
Also after I got the suspension dialed in I decided do a homemade hi-line or high fender setup on my YJ which raised my fenders 3.5". So then I had to go back to my suspension design and lower the jeep while keeping the flexy suspension I fabbed up. I took 2" off the height by reworking axle spring pads and raising/frenching the spring eye mounts. Lowering 2.5" took 10x more work and thought then any kind of lifting ever did.
Lol, sorry. Im a sharer...
Switching to decaf now.....
Mechanical engineer here who has designed in both inches and the metric system. For most things in the metric system with components of the size you are referencing, it would be something like 55.25mm (a bit more than 2 1/8"). Growing up in the US, inches and feet were intuitive but in my schooling and career I've come to truly appreciate the simplicity of the metric system. For example there are 10 millimeters in a centimeter, 100 centimeters in a meter, and 1000 meters in a kilometer. Additionally, volume measurements are linked to length measurements. 1 milliliter of volume is equal to a cube with every length being 1 millimeter. Also 1 gram of water occupies 1 milliliter of volume. So in comparison to inches being broken into fractions, 12 in per foot, 3 feet per yard, and 5280 feet in a mile, I think the metric system makes a lot more sense.
Most commentaries pretty much nailed it with regards to the optional use of the different metric units, however, the final unit choice in manufacturing drawings (which are the technical language/information transfer method) is almost always set by the scale and accuracy requirements.
For example, if a part is 3.5 meters long but needs that measurement to be within a (+-) 0.5 mm of the nominal dimension, than usually the measurement would be given in mm, 3500 mm (and the tolerance).
This is what is familiar to me at my neck of the woods.
Very nice intuitive work.
Seems like second nature and nothing seems to worry any of you guys.
Love your videos and your attitude
Cheers
FYI on tires that large, you may discover that the "Cast" centerline wobbles a bit and can give you inaccurate readings. To fix this, you can spin the wheel and tire and make a chalk mark to avoid relying on the cast tire tread. With the chalk centerline, even if you don't hit the exact center, your line is at least accurate front to back anywhere on the tire and works for things like toe in. Just a trick I learned the hard way.
That's a really good idea!
Tldr doesnt matter

That Anderson Lumber truck @ 9:30 brought back a flood of memories from early childhood going to the lumber store with my Dad to get a paper bag of 16p nails and rootbeer barrel hard candies in his '52 Dodge. Tears in my eyes!

Facts
me drinking my coffee enjoying matt on sunday morning 😂
Love that Matt can use the impact and know when to stop and be within reason of the proper torque.
One thing I will mention on torqueing wheels, when over torqued the risk isn't just marring the threads, you can actually stretch the studs which weakens them and you add the risk of them breaking. I own my own semi truck, over-torqueing lug studs can end in sheared studs and wheels running away.
Keep up the good work guys, love watching all the shenanigans you get into!
On cars, the torque is especially important on light alloy rims - if they are tightened too tightly, microcracks form on them and you can lose the wheel, especially when the load becomes high such as when cornering and turning at higher speeds where you absolutely do not want to lose either steering or braking ability!
Sheet metal rims have a much greater tolerance and there it is very true that the threads give way or that the bolt comes off due to fatigue.
Hi Matt, in Germany, engineers and hobbyists usually use millimeters [mm]. They usually omit the indication that it is in millimeters. So if the bolt is to be 0.25 meters [m] = 25 centimeters [cm] long, they say 250. But you hear other specifications, too, mainly in stores like Home Depot.
When you measure something with a caliper, you usually put a period after the decimal point. If you should make a component "a little" smaller on the lathe, then many also say that you should take away 2/10. What means as much as 0.2 mm. Fractions, however, are only used as multiples of 1/10 or 1/1000.
It is similar with the threads. No one would specify the pitch for the standard thread. A metric thread is not M8x1.25 - it is M8, unless you have something different. Then the pitch is explicitly mentioned. So for an M8, I would pre-drill 6.8 and then tighten the bolt with a 13 wrench. Whereas a 17 wrench can be a wrench and a synonym for a beer bottle opener ;-)
Speaking of threads. Here, with car tires, pipes, ammunition, powder charges, imperial units appear again and again. Likewise, certain, mostly older professional groups also have special units that not everyone knows. As an electrical engineer, I find it confusing that in Australia millimeters are often referred to as mils, whereas for electronic components, even in Germany, the unit mil = though = 1/1000 inch is often used.
Best regards and thanks for the great videos. I am looking forward to the Wrecker Games like a hawk.
Of all that, I got that a 17 mm wrench is a beer opener.
Measurements on my offroad jeep are done in quarter inches and an angle finder. Especially when it just gonna bomb through the forest and parts will be replaced or changed the same month, why bother making stuff perfect.
In cars, the Japanese have often an mm smaller bolthead so 13 is 12 and the treads are tighter so M 12 is often 1,50 mm instead of 1,75- not fun to try the wrong threads...
I love the respectful way Matt and Tom Tom exchange ideas and solutions. I also really like the way this episode was produced and how they showed Matt and Tom talking over the solutions.
It would be nice to see a reunion of everyone who worked on the truck. Maybe an update from those who want to share what they are doing now. And a group picture.
Tom Tom is such a good add to the team!
Hey Matt, 'decimeters' (=10 centimeters) is not normally used, tradespeople etc. normally use total millimeters, (mil). so I would be saying things like 75 mil/435 mil/ 1260mil etc.Whereas someone buying fabric/curtains would more than likely say 75 centimeters. 10ths/100th's of a mm would only be used in very fine tolerances, engineering etc. eg. 12.65mm/26.355mm. mm are fine enough divisions for most work like cutting timber sheet metal etc. Once you get used to it you WILL find it so much easier. Cheers from the UK Jim
Yes Matt, all in millimetres, I’m a boilermaker by trade in Australia and also have my own rock crawler . And we use 0.5 in our measurements. So if it’s 54.5mm then that’s what we aim for

30:22, Tom Tom respectfully: "If we flip the shock around...and just rework the back of this, how much work is that? Is that a ton of work?" Dear Matt: You really couldn't have appreciated this best of all solutions for the shocks more gratefully than to start implementing it together with its creator without hesitation. Sometimes it's damn hard to acknowledge with words that also "the other one" has it simply fully on it. I understand: You brought the whole thing into being. But the more you share it, the more it will fulfill you. It is great to see with you - looking at yourself critically in the mirror - how the successive admission of this realization enriches your life. You are a great team, all together! Do not stop growing in this way.
Love all the guesstimation in engineering here and how well it worked! I've always been amused at people using different colors of Loctite for different things. I've always exclusively used red for everything, even if I plan to have it off within a year. Never had an issue breaking it loose.
It seems Matt & Tom Tom get to the same place, they just have a different path to get there. I have NO DOUBT that they will continue to both learn from each other on these processes and what you can, and can't, get away with. It is great to see that they can respect each other's differences.
Ron Pratt might say: 5+5=10 and 2+8=10
In Australia we use millimetres all the time eg 1021 mm, and 41.3 mm. However it also depends on your tolerance. So for big distances we would say 24.346 metres (like you would use yards, feet and inches) Rgds Peter Barber, Sydney
Tom’s generally right. Use mm until you get a big enough number. Centimeters is sometimes used. For smaller than a mm you’d use a decimal (e.g. 2.5 mm). Different areas of the world will do it a bit differently so you mileage may vary.
I'm a Fitter by trade in Australia... In engineering and fabrication we use millimeters for basically everything, right up to and including dimensions that go into meters. Something that is meters long would be written as 2453mm for example (which is 2 meters, 45 centimeters and 3 millimeters long). It's easy and fast to keep it in millimeters. If we go into fractions of millimeters, it would look something like this 2453.5. And yes, we could simply say the .5 as half a millimeter, rather than saying "point 5" but thats more of a personal thing and it doesnt really matter how you say it.
Working in metric is easy and fast because you simply move the decimal point to get to the next unit of measure. 2453mm = 2.453 meters or 245.3 centimeters or even 0.2453 of a kilometer.
Everyone's going to love this. I work for an international engineering company as a mechanical designer (20+ years). We will use dual dimensions with inches to 2 DECIMAL places and metric to 1 decimal place. Ex. 2.25 [56.0] inches [mm]. We will often reverse those depending on the country where the project is. We like to mix ASME with DIN and ISO too.

You should start your own channel and show us the work you’re doing
Metric: Here in Norway, it's common to use mm, cm (skipping dm) and m. The less detailed you need to be, the higher the unit. Like 4 meters and 22cm would be 4.22m and would work out fine for lumber construction, but if you would cut the same length with high demand of precision, you would probably go 4220mm.
(Ofc there is micro, nano meters and pico meters as well, for the need to be ultra precise, but not commonly used. Micrometer is used in shimming valves, and nano meters for race engines).
The thing we do that don't make sense, is what Matt mentioned. We do use inches on wheels/tires.
My wheels are 305/45R20 - 305 mm wide, where the sidewall is 45 % of the width, and the rim is 20 inches. So a nice mix of everything. :p
We also measure our tv sizes as inches diagonally for some reason instead of cm.
Only dressmakers use centimeters. Any professional or engineering type will only use millimeters and microns.
Hi Matt !My response on your metric system question : For small measurements just use milimetres(mm) .For longer ones you can use centimetres (instead of tens to hundreds of mms) or in combination with milimetres ( 24,3 cm = 243mm)..Decimetres are rarely used so either use metres or a combination of m and cm( 1,25m = 125cm) .It is convenient and simple either way .FYI : Metric vernier calipers usually go down to tens of a milimetre which equates to a few thousands of an inch.
While you write it down using one unit (ie, either 1.28 m or 128 cm), you might vocalise the former as “one metre twenty eight”. One reason for this might be that when reading numbers with decimals you are supposed to read them “one point two eight metres” but you of course visualise this as one metre and 28 cm.
in automotive/mechanical engineering we never use centimeters. all units are in 1000 divisions, (i.e. kilo, milli, micro, pico).
Don't confuse the guy with cm. Only dressmakers use centimeters. Any professional or engineering type will only use millimeters and microns.
Another great video from the whole crew in Hurricane! Looking forward to the Wrecker competition, it appears Matt has it in the bag for that #1 trophy!
I would like to point out that in your shop you have a bridgeport that can do precise cutting which would be a good option if you lack a lathe, but, i guess an angle grinder works :)

Matt - I use mm because it is simpler to manage than inches. Forget the centimeters and just go mm. You can fractionalize mm. I've been doing mm for a very long time so it's kinda automatic but you should do what you are comfortable with.
I'm in the UK and was taught in metric but grew up with an older generation who worked with imperial measurements. So I'm a bit odd that I use a mixture. Generally metric for more precision stuff, and imperial for woodworking (timber still sold in imperial size equivalents over here) or if I'm working on an old vehicle. My Series 3 Land Rover has a weird mix of thread sizes from the factory - BSW, BSF, BA, UNF, UNC and metric!
Dear Matt,
As a Canadian, We definitely don't use Decimeters. No idea what that is. We use metric for most things, but honestly most people still use Imperial for building/construction as well as height and weight.....
That said the conversion between millimetres and centimetres is so easy to slide between you don't need to 'fraction' it. 221mm is 22.1 centimetres. So looking at a tapemeasure or ruler is really simple. You can find 22cm and add one extra 'tick' on the scale (ie. what might be a /64th of an inch is just 1mm) On the math side it's much easier.
No fractions to do in your head. 3"1/16 + 2" 7/16 doesn't happen. THAT'S why someone commented to use Metric
I’m imperial but raised in Canada. Typically you just use one unit, but use the unit that best describes the accuracy you are trying to achieve, be it microns, mm, cm, m, or km.
Isn't Canada in Venezuela?
In place of microns, butt hairs are perfectly acceptable...
Yes, millimeters, and yes with a caliper you can go decimals of a mm. I find the metric system easier to use in most situation unless I'm framing a building. I love the "fix" to the shock towers. Maybe you can make a bolt on cover to protect them because tire deflection can be significant in certain situations. Love this channel!
I'm Brazilian and we use metric as default here. You're right about the decimals of millimeter, we use them. Instead of fractions.
I worked as a industrial piping designer for oil rigs and refineries and all engineering designs and plans were in millimeters, regarding the size of the parts. Millimeters are the standards for mechanical engineering and industrial constructions such as piping, metal structures etc.
For civil engineering the default is centimeters but I've seen some heavy precision aficionados using millimeters in their plans, and meters are generally used for land plots measurements, but I also have seen some of those in centimeters.
Oh, and about Matt's question about decimeters, I've never seen anyone using decimal scaling anywhere except in school homeworks where kids are learning measuring scales. That applies to deciliters as well. 😅
Hi Matt,
I'm a mechanical engineer in the UK and I basically only ever use milimeters (mm).
I'm rarely working with anything larger than a few metres so would still use milimeters for large measurements (e.g. 1500mm)
Rarely I might specify milimeters with decimals - e.g. 2.45mm (two point four five milimeters), but that would only be on an engineering drawing, you'd rarely need to say a measurement that precise to someone.
I can't speak for the archetects who likely use metres, or in casual use cm might be used (e.g. for a persons height) - but in an engineering setting it's always milimeters.
Challenge Matt, purchase a tape measure that has both the imperial and metric system on it. It wont take you long to learn how easy it is to measure with the metric system and you may over time start to preference it. When I was an carpenter many years ago you would sometimes use the terms "full or bare" to break down one millimetre. e.g. 55mm full means about half mm longer
Yes Matt, 54mm would be the lingo, like in the bicycle industry for example. Always use the more convenient measurement, the bike industry had 1" head tubes, which were 25.4mm. Both Imperial and Metric are used back and forth.
Yes. The basic measurements are 'meter' for distance. 'Grams' for weight.
"liters' for volume. Then just add prefixes. Like "kilo" for 1,000.
Wrenches in America are 1/64, 2/64 or 1/32, 3/64, 4/64 or 2/32 or 1/16 ...

Fractions are frustrating.
Decimals are despicable.

And then God made Dura Ace 10 pitch track parts, instead of 12.4 (1/2 inch)
Even on bigger dimensions, they often use millimeters. For example, instead of 1.5 m, you would say 1500 mm.
Ya know, I'm impressed by matt's ability to fabricate on the fly, but as an engineer it's obvious to me that some preliminary drawings and CAD models would have simplified and shortened this whole build process.
Everyone probably answered to you, but usually when working with exact measurements, we just go with the total millimeters. For work done by hand tools (so no CNC), there's absolutely no need to go into decimals of millimeter (like 25,4mm, which would be one inch), you would just markup 25mm and cut it there or if multiple inches that are converted to millimeters you round to closest even number and it's going to be pretty much the same, as it's so fine measurement anyway.
Millimeter is essentially some what more accurate than one sixteenth of an inch (1.6mm) which is commonly used as the "most accurate hand tool measurement", so you would have to use 32nds fractions to be closer to millimeter (1/32" = 0.8mm), and that's pretty much the absolute limit with anything that's not done with fine cutting tools on CNC. Even going by the millimeter, your error most likely will be +/- 1mm just because it's getting so fine for any hand tool to do the cutting, so understandably 16th of a inch is enough for any shop work also.
And to be honest, I don't care what units anyone uses, the results are the same when you use fractions. For us who are used to metric, it's just easier to go with 1527mm, 372mm or 55mm or whatever measurement we need to get to, instead of mixing feets, inches and fractions of inch.
In Australia, as a home handyman and a ticketed Fitter and Turner, I use mm up to a Metre, 1,000 mm; for example, a timber platform is 800 x 600 mm. Over a Metre, I say 9M long or, say, 9.23M. For long lengths that need accuracy, you can ask for 9,235 mm.
With a fitter's ruler (showing seconds of a mm) or a lathe in tenths of a mm, you can mark, say 6.55mm, using a metal scribe or the measurements on the lathe. Millimetres (you'd be in 16ths or 32nds) allows for a closer more accurate swarfe cut in my case.
The "Deci" piece is not used widely - you find European bottles of alcohol labelled in Decilitres, but that a big bottle! Ten litres.
It's hard to subtract 13/16 from 23/32 in your head, subtracting 4.55mm from 16.2mm is easy.

@@gymshoe8862 wtf?
To be as accurate as possible we usually use millimeters as our preferred unit. Sometimes, if the scale is bigger, we’ll use centimetres. On the measuring tape it gives the length in centimetres and then all the lines are spaced 1 millimeter apart, so if we measure something that is 3 cm and 5 mm we’ll just call it 35 mm or 3,5 cm, but when measuring for accuracy we say 35 mm
And we never fraction. We always use the decimal point
Only dressmakers use centimeters. Any professional or engineering type will only use millimeters and microns.

You can see Toms eye twitching when Matt tells him the farmer fix. 😆
Over-torquing also puts unneeded stress on the threaded studs and if too tight can actually cause them to break, especially with extra large tires. I have a friend who had this happen to him and wheel came off on while traveling down the highway. He figures it was the shop he had it at overtightening overtightening his lugnuts, he had been working on one wheel and had a heck of a time removing it. After finding that, hindsight he should have gone around to every wheel and properly torqued everything.
As far as metric, Tom-Tom is right. At my work we sometimes put the total millimeters on our drawings when we want to dual dimension something, sometimes with a one or two place decimal if you need real specific. We don't fraction millimeters. To each their own, we are in the US and still use imperial as the driving dimensions for most everything we do because that's what we get in stock steel. I don't' think it's any easier to use one over the other. Know the conversion by heart and go with whatever is easiest for you.
On the metric question, in my line of work dealing with ships and ship construction/fabrication, Tom is correct. Just stays millimeters for most all cases, sometimes written after built up to meter, but more common to write 13,500mm over 13.5m. Entirely skip centimeter. Anything smaller then a millimeter just goes to decimals. 11.5mm, 11.2mm etc., not fractions.
Australian here. We changed to metric when I was still in primary school, (grade 4 or 5 I think). When I did Mechanical Engineering at college they taught us to use mm for small things and meters for large things. And metric is base 10 so you would never use 7/8 of a mm. The whole point was to eliminate the complex fractions used in the imperial, (English), system. So something 2 3/4 inches would be 69.85mm. Although, measuring with a ruler you would probably just round up to 70mm. For really small measurements, like 1 thousandth of an inch, it's 0.0254mm or 25.4μm, (micrometres). I am really glad I don't need to do all the complex fractions in my head. Having used both, I'll take metric any day.
P.S. Don't lose the 10mm socket... :P
Agree with Robert, but would add some bits from a New Zealand perspective. We use mm, and call it, say "50 mil". But if its longer than a meter, we would say "twelve hundred" and everyone just assumes you are talking millimeters, If its exactly aligned to a meter, then we would say "2 meters" rather than "two thousand mil".
Having said all of that, we still use feet and inches for someone's height - 6 foot 2.
Loving the extended videos! Love the 4 wheel steering. Can't wait for recovery's. It's gonna be a cake walk
Not without the key
You would call 1 inch 25.4 mm. The Fab shop I work at if the prints are in metric they'll go out one decimal in mm. So I might have tubes 345.8 mm long for example. Love your channel from Wisconsin!
Hello Lizzy from a welder to another welder you're doing an amazing job. I think it's cool you're learning how to Tig and you're right about trying to find a place for your elbows and arms to rest while you're welding that's one of the rules of thumb always try to be as comfortable as you can and steady rest your welding. From my experience with welding I have received flashburn a few times mostly the worst was TIG welding. I don't know if any of the old welders have told you at the best remedy for flash burn of the eyes is juice from a potato. the last time I got flash burn I woke up at 2 in the morning with the most pain ever felt in my eyes I was at a friend's house sleeping on the couch without knowing where the potatoes were and didn't want to wake anybody up I found my way to the kitchen the first cupboard I look down in I found potatoes actually found a cheese Shredder on the counter proceeded to Shred the potatoes and just put it on my eyeballs relief within 5 Seconds anyways be careful with that TIG welding always use good helmets but I think you know that.
Years ago I was working electrical in a service panel. I was told I had to leave it live because of what it was supplying power to. Something got too close, didn’t touch, but close enough to allow the electricity to jump and arc between the two points. I didn’t get shocked but several hours later experienced the worst physical pain of my life from the UV burns to my eyes. I quickly (about a week if I remember correctly)made a complete recovery but oh would I have loved to have known this tip. Thank you for sharing.
A welder is the machine. A Weldor is the technician. Like Sailor and Taylor.
I always wear plastic safety glasses even under my mask when welding. That way when I flip my mask up and forget to put it down again if making a quick tack at least all of the UV is blocked. Even cheap clear poly-carbonate safety glasses block almost all UV light.
I have gotten in the habit of just always wearing safety glasses in the garage so they are already on my face when I weld, but it's it's not just for welding its for general eye protection too. As I get older I become more aware of hazards like that.
@@gordbaker896 Never considered that - too busy wincing and swearing every-time they call a wheel a "Tire".

As for installing the U-joints with a hammer, anyone can use the right tools!
Using red loctite on the steering before you check to make sure it's right is like doing a crossword puzzle in sharpie. It's probably going to be ok if you are a pro, but not recommended for an amateur.
I'm loving this build! Thanks for all your hard work :)
Aussie here, we use millimetres for all building and fabrication. A 3.255 metre length of wood (10' 5/32") would be a 3255mm (we would probably pronounce it "thirty two fifty five", unless the boss is very specific haha). Typically we don't say "3 metres, 25 and a half centimetres". For smaller sizes, we might say "two point five four centimetres" OR "twenty-five point four millimetres" (thats one inch for you american folks). We use inches for tyres, waist bands, belts, and surfboards, don't ask me why!
Matt, dressmakers work with centimetres, fabricators work in millimeters only up to 1 metre. After that we work in metres and millimeters. Eg: 1 metre 562 millimeters until you get to 2 metres... and so on. Hope that helps.

Millimeters all the way up to a meter then it's meters up to kilometers. For really tiny things, 0.1mm, 0.01mm, 0.0001mm.
Loving Matt and Tom's chemistry. The way they clash is great.
22:05 it is always a Faktor of 10. 43mm Are 4,3cm Are 0,43dm Are 0,043m and so on
Not really mm all the way. building trade 5meter isn't 5m it 5000mm or 7.5m would be 7500mm
the Point ist you always can move your , left to Right because is always based on 10 all the way up to Kilometers down to Micro Meter, easy to Math
Who is going to measure micro to km? Matt certainly doesn't need to
@@Factsandlogicthinking des je doesnt Need to, the Point was for understanding of the System as a hole. I think je is Fine from Meter down to mm
On the metric system, it depends on where you work: If you work with metal, you usually talk in millimeters. So you can say 455 mm to a nearly half meter. Everything shorter will be spoken like a 1/10 of a millimeter. When you work with woods, its often easier to speak in centimeters :D
By the way: I love your leadingship! You are such a cool CEO and you have such a cool crew! Love your videos!
Yay! Great progress guys, thanks for taking us along! I love your work :D
You've probably had several thousand answers to your metric question but I'll add my 2 cents worth. In the construction industry here in Oz we use strictly mm, i.e. a house will be 8450x14960mm overall (and we would read that as, 'eighty four fifty by fourteen nine sixty,' because we're lazy and saying, 'hundred,' let alone, 'thousand,' is way too much effort and by only using millimetres we don't have to specify, again, saving words!).
In furniture making we'll work to a tolerance of 0.2mm, 'point two of a mil,' (gotta say it with an Australian accent!).
Verbally we may say, 'we're out by half a mil,' but otherwise don't generally use fractions and certainly not in written form.
Tyres (tires) yes, are weird... our rims are measured in inches and tyres come in either imperial (like a 31x10.5R15) or metric though metric sizes are retarded. A metric tyre might be a 265/65R17 which is 265mm wide with a side wall 65% of the tread width and a 17 inch rim (which amounts to basically a 31" tire!). Whoever invented that system was a creative individual but at least we can still run American made tires on our vehicles...
Anyway, back to the wrecker!
Looking like a fun build Matt and crew, on the grease question, I personally use mystik, or royal purple, with working in the oilfield, as well as farming at home these 2 greases put up with alot and are very good.
This is my favorite channel. The team work, the banter, the humor, the people; all just awesome!
regarding the metric system, it depends on what field you are working in. So for example if you are building a house you would most likely use cm (or even m depending on the size). For something like the wrecker you would most likely stay in mm, but it kind of does not matter since going to cm is just moving a decimal point (the greateness of the metric system).
But you allways say a measurment just in one unit so for example 2,5cm would be spoken two point five centimeter, or twentyfive millimeters. (but never two centimeters and five millimeters)
The conversion from metric is: 25.4mm to 1 inch. 2 and a half inches equals 57.15mm.
For most general metal fabrication workshops using a measuring tape, 57mm is close enough. For higher accuracy (bearing clearances, machining etc), the full 57.15mm would be required.
The extra 0.15mm is just 5.91 thousandths of an inch so in day to day fabrication for many jobs, you don't need to be that precise. Hope this helps, can't wait to see ya's at KOH 2023 🙂
To add to this, yep wheel rim diameter and width are still in inches (world standard) but tire width is quite often metric (passenger car) or imperial (4x4 Jeep etc) and mph is still popular in drag racing, especially with us older guys 😁
@@James.._ If you check national racing, in Sweden atleast, the speed is measured in kph.
Regarding measuring, I agree. When measuring longer distances, say the length of an axle, or width of the body, depending on how accurate you have to be, you'd either go cm,mm or if you measure for precision you measure mm all the way. So if something is a meter or more, mm go into the thousands. 3,5m = 3500 mm.
Here in Europe we use only millimeters when technical measurements are involved. 234 mm, 1230 mm, 23 mm and a half, and so on. Wheels, you are right, come in inches. For us, your measurements are like Chinese language. 😅
I love how Tom just goes along with it when he knows it isn't right, but it always works out. I love it. great one two combo on the channel. Tom Tom getting funnier. Pink Grease - Timken.
I think they are both learning from each other in this team. Matt is rough and ready but knows if something fails it will be out on a track somewhere with only basic tools. Tom is a workshop engineer who knows how to do the work properly but not always practically. They are both giving a little more to the other each project.
Lizzie, build or collect a few tools for building rests. Vice grips work well with extensions welded on for resting on. Just clamp them on to or near your weld and you have a rest. You can also use adjustable wrenches of various lengths/sizes for doing the same. In a pinch you can tack on a bit of material to act as your rest.
Better yet, apply for scholarship to a trade school that will teach you some more welding skills. 🤠
The TH-cam welding tutorials are great, but kinda like looking through a kaleidoscope.
@@-HighTide oh 100%. I don't know how much she earns with Matt and team but given she seems to be pretty natural at this it could be a big money job in no time without even having to work every week. A friend that does the glow industry does 6 months on 6 months off but has obvious risks.
Lizzy, specialized alloy pipe welders in industrial construction can make low 6 digits per year. In nuclear construction, even more. Quality high end welders are in very short supply.
The big money is in welding NDE inspection, especially for level 3 or 4 inspectors. You can pretty much write your own ticket.
gud idea
