The way you keep coming up with visual jokes is absolutely amazing.
Did anyone find the 'subscribe' ?
Cool test signal pattern pp
I stopped turning something at work to watch this in the bathrooms
But was it titanium?

I guess no one said anything about a near 20 minute bathroom break.
If you get any complaints, just tell HR that you have put yourself through some extra training, and that you needed to go and refer to 'STFUs Tele-correspondence remote training's tape 21 before completing the job. You've just gone from slacking off to being a go-getter. Now just sit back and wait for the promotion 😉👍
@@aviationic8145 it's a big place thankfully!
That's one of the best tutorials on vernier scales I've ever seen - and I've seen a lot of them (I teach that stuff).
LateralThinkerer weird to think people dont know that, i had them growing up and learned that at home
Agreed, this video is the reason I know how to read vernier scales.
Add this to the curriculum
I love Verniers. The concept is just so cool. I generally won't have a dial or electronic one because of this, though there's a cool tear-down vid showing why the electronic calipers are _in fact_ actually Vernier (internally).
I've used a vernier caliper for years....its flown around the workshop a few times (butter fingers) and I don't trust its accuracy. Cue Mitutoyo 12" unused gift. Back in action....I just wish my sight was better!
As a non-precision 3d-printing sort of guy with a lazy set of digital calipers, verniers had always been a mystery to me - but now I have been educated. Thanks, STFU!
I have some here that I have no idea how to use. It's in 1/1000" and 1/20mm and not marked in inches, either. It's odd, to say the least.
Edit: OK maybe it is in inches lol. I just didn't know how to read them. Thanks, Tony!
There is digital and analog calipers?
learned that at the age of eight, its great to help your dad building stuff as a kid ;P
@@n1663rdigital, vernier, and dial calipers exist. I prefer digital for speed, vernier for accuracy and dial for mix between them.
Get a CAD package that supports background imaging for a quick dimensional ipiphany.
Holy cow, I just learned how to use calipers. (not sarcastic)
@Shambles1980TRealOne I've been a pro this whole time!??! :)
@@jasonstahl73 lol! Well done!
Or do as I do and use digital ones when no one is looking then get out a tape measure and say that’s *** and surprise every one with how accurate I am with a crappy 20year old Stanley 30meter tape.
Jason Stahl yeah, and next level pros even use them to scratch mark the workpieces and save lots of time 😉👍
Me too, but I just forgot.
In all seriousness you should make videos for trade schools.
The work you put into these videos to be informative in the clearest possible way and their comedic timing comes across as effortless.
That is a testament to how good you are at it.
C'MON MAN!! Why would he want to do that?? He has it nice and easy, making flower stands, out of precious metal, and big piles of chips out of small piles of whole metal!!
Also, you could make videos about how to make videos.
He does kinda. Awhile back I asked a buddy currently in machining school how many ToT videos he'd watched. He said his first one was the day before, shown to him in class by his instructor.
@@tylerh7647 Commercial Use!
Tell 'em to Pay Up!
:-)
With the good jokes in editing, i would be glued to them in school
The sheer amount of jokes and education packed into your movies is astounding! Thanks for all the hard work you do!
This Old Tony I've been sanding on my high speed steel since you released this video and I'm happy to report the cutting tool is finally done.
I love machining titanium! And please stop overwriting those rental VHS.
I was impressed by your video showing you machining various small screws from titanium.
I miss VHS. ah the 90"s.
What is this VHS that you speak of?
Beta was the way to go...
@@TrailRat2000 VHS = Very High Speed.... Loads better than HSS :)
I watched old cartoons so i know that ICBM nose cones use ACME threads
My mother-in-law has titanium knee joint replacements. But she didn’t make them herself, despite all the potential cost savings.
I had a comp sci teacher in high school whose former occupation was designing ICBM nose cones. They actually do use ACME threads.
Earth shattering KABOOM surely ;)
Of course Acme threads, was not the manufacturer the ACME rocket company?
"12 of those thready things"
I sure wish you would cut down on the technical terms, my edumacation didn't cover this
..He did not include the required DEPTH of the threads. Is there a standard depth for 12 TPI ? it would of been nice if he had mentioned it.
@@DNulrammah while my comment was a joke about tots joke, the answer to your question is yes.
No, I am not trying to be a jerk. Please read...
I have not watched the video in a year and only vaguely remember the subject matter of said video, but I can give you some answers on this.
The depth of the cut is wholly dependent on....
1. the diameter of the part
2. the type/profile of the thread pattern
3. the material being used
This is not the exact answer you were looking for, but there is an engineering specification manual that's constantly referred to by tot that can provide you the information needed.
Also, quite often tot flashes the page of specifications he is using from that manual. It's quick and easily missed but often it is there.
Hope this helps somewhat.
There is also a separate video(s) on cutting threads.
Upon closer _closer_ inspection...
Upon closer _closer_ *_closer_* inspection...
_continues on until vernier scale is in planck lengths_
Just call it a 'very near scale' like in the 70's or let it slide and jump to digital physics...
I honestly much appreciate the vernier calipers reading guide, thanks TOT!
As someone who had to figure out how to read Vernier calipers on his own, this video showcases it in such a straightforward and easy way it seems like nothing, if all you have is a set of calipers and a part, it takes some time to figure out why all those lines don't match up.
He did do a great job explaining how to read them. Kept it as simple as they really are.
I forwarded this to my college teacher. This may get shown to several years worth of students, in one of the top schools for machining, in the state.
I have to admit, I've owned and used one of those for a long time, never paid attention to the second measurement. This just blew my mind, this changes everything.... or rather this changes nothing because I've never needed this much precision but this is still awesome to know just in case.
I accidentally mailed back the WRONG TAPE!! DO NOT OPEN IT!! I know it will say Lord of the Rings but it's not what you think!!!

Great episode
@@gamemeister27 I heard it makes Crotch Capers 3 look like Naughty Nurses 2
If I ever get stranded in the wilderness, I am going to use T O T instead of S O S.
Tot in German means dead , hehe
I assume it is because you ran out of gas, and he will rescue you just as soon as he gets done fabricating a Jerry can.
T-Riffic TOTi. Outstanding graphics on the Vernier class and the Retro was spot on with the all the aliasing and color work. Brilliant and no fires! Better and better Mr. T! Thanks for all that work and fun....only one abnormal espresso aspiration from the tool room guy, but a good cough with it. ;-P
"The shop foreman will already have reamed your bung."
Don't threaten me with a good time.
@ mereth: lol, he said as safe spaces filled up everywhere!
Totally lost my shit, brill
@@pauldunkley494 Of course you did. Your bung was reamed.
Had to rewind twice to be sure I heard what I thought I heard lol (imma on phone don't have computer cuz I was homeless 3 years in my car and now Im not)
@अल्ली X well a bung hole is slang for a bum so yeah he kinda did
I’m going to be very upset if we don’t get a “building your own surface gauge” video...
Surface gauge or RIOT!
"Meatball and her Kittens Build A Surface Gauge!"
yeah those are the kinds of declarations that need to happen
Yes that video has been a long time coming.
We are still waiting on that Eminem song "My Salsa"
The drill bit in the tailstock to catch the parted pieces is genius.
Your comedy always makes me forget about my long day. Thanks Tony.
Hi Tony, hint from across the pond (UK) ..if you get a hard spot in a drill hole in any material and just want to remove it without having to buy a carbide drill or chance ruining one, then use a cheap masonary bit. Just grind the edge as a normal drill on a green wheel BUT also grind the flute face flat (so it presents an almost square edge to the work) this makes the cutting edge incredibly strong and robust. Once youve cleared the hard spot you can return to normal drills again. I always keep a good selection of masonary drills in the workshop for this purpose as its quick and saves a fortune :)
I watched these videos religiously even have a ritual for it even though I never thought I'd ever touch a lathe...until I did. I now work at a powdered metal place and I owe that decision a lot to ThisOldTony channel for making those machines now look less scary and less intimidating.
Thats how a youtube education is supposed to work. Congratulations man. I'm a qualified machinist who watches these videos to remember all the little tips and tricks on jobs that only pop up once a year or so. When I say remember, it's quite often learning for the first time.
Way to go Dave. There is sooo much to learn and the joy of it is you will never stop finding new things to do, see, learn.
Welcome to the fraternity.
Now THAT is one for Tony to hang on the wall!
I’ve always found titanium pretty nice to machine. It’s also a volatile metal. If you have very thin, stringy chips you can light it on fire with a lighter. Has a very bright white flame.
Me thinks you're referring to another 'ium' metal, Magnesium...
@@GFTP100 Titanium is combustible and has a silver-white flame color.
I always bring enthusiasm to my projects! working on bringing skills next
It is actually VERY easy to anodize TiAl6V4 properly. All you need is a bench power supply going up to approximately 60V DC and you can just use Coke as an Electrolyte because it contains phosphoric acid. Hang a strip of stainless steel or even titanium into a container filled with Coke and your titanium workpiece too. Connect the strip of metal to the negative terminal of your power supply and the workpiece to the positive. Apply around 30V for a nice blue finish, a little less will result in a nice golden finish. (Don't drink the Coke afterwards because it now contains dangerous stuff!). Also, if you need bigger titanium cutoffs, just send me an address where to ship them😉. Greetings from Germany
If you're just sending out titanium cutoffs...... :)
One part "H" Two parts"S"..........That was brilliant! Now to find something to clean tea of my monitor!
Keep up the good work!
Man, that shit gave me life.
I know why I usually don't eat and/or drink while watching TOT videos...^^
Yeah I lost it too 😂
What does tea of monitor taste like? ;) jk
That part had me laughing as well!
I once gave my cat a juice shower while he was chilling right besides me. He stays away from me when he hears TOT's voice ever since.
"That one's pretty"
That was hilarious
OK, so the combination of the actual usefulness of the content (100 out of 100) and the quality of the stand-up (or sit-down) comedy that content comes packaged in is out of this world. Huge respect!
I thought I was the only one who had that picture of Abom... :-D :-D
Some of us paid plenty for that photo. I got mine signed!
He's really slimming down these days. :-)
It was in his calendar for the month of June to coincide with some kind of pride month.
Hahaha
He better be a good friend. I've seen that big wrench on his warning sign.
Step one. Swap out the titanium for aluminum when nobody is looking.
Or he could have just sent Ti-3Al-2.5V
hahahaha
This comment coming to you on 1/17/2020. I came back to re-learn how to read a caliper. I've looked everywhere, but this video set the standard for how I can learn it.
And I completely am writing this comment in the tone of voice used in the video. Amazing.
I love this guy's modesty and sense of humour..... it tells me the frustrating limits I've come up against in the workshop are happening to other guys, too.
During my apprenticeship, we used to call the vernier calipers „Schätzeisen“ which roughly translates to „Guessing Iron“... it drove our foreman/instructor (?!) insane :D
lol awesome.
I tell my machining students their vernier calipers is the equivalent of a fabricators tape measure. Good for rough measuring.
Real measurements are done with Micrometers.
We called them shifting spanners 😂
Our nickname was 'very near gauge' . Schätzeisen kommt da im Sinne sehr nah...
@@notcrediblesolipsism3851 lol
Damn man! I spit my coffee across the room with that Abom job shop cutoffs picture. No thanks for that memory😏
Yeah... and i can't UNsee that either!
The editing makes is great! I know what kind of effort went into this - thank you very much. You've done the extra mile for us.
This is by far one of the most entertaining videos on the whole of TH-cam. Seriously, I've watched it 3 times now and it cracks me up every time.
Before I started watching your videos I knew next to nada about the basic principles of machining. I've learned so much about a subject that I never knew I was interested in. So, thank you?
Loved the 70's graphics with the tracking issues.
'70's? I took a video based chemistry class in 2000...that looked exactly like this. Yes, it was on VHS tapes.
VHS wasn't popular til the 80s
This episode was so good that I got my calipers to understand them and got a feeling of immersion, suddenly I was measuring the same cap that ToT was holding in his hands!
I loved the shorts on going into more detail about the parts and the how to's. I've never needed the accuracy need with the vernier calipers and never bothered to learn how to read the Vernier scale part of the calipers. That was awesomely helpful! thank you!
Your content is so freakin great Tony... glad I found your channel. My dad has run his small machine shop since long before I showed up, I am by no means a machinist, but can weld and run a lathe/mill enough to build stuff for my plane... but because I grew up in this environment it will always mean something extra to me. I have worked with some Ti and drilled it etc... it was nearly a nightmare! Really enjoyed this! You sir know your stuff, thanks for the great content and not just the learning aspect, but the humor.... it absolutely takes it to the next level.
Adam spitting out coffee though a barely stifled shout laugh in 3...2..1...
'If you've watched enough looney tunes, you'll know that ICBM nosecones are screwed on too' 🤣🤣
The "job shop cutoffs" joke was amazing 🤣🤣🤣 I think Abom should do a fundraiser video with those exact shorts.
Always fun to watch,thanks Tony
I'm glad to hear you machined your own titanium hip replacements. I bought mine "off the shelf" and they are just awful.
I'm a wood worker in shipbuilding, so all I get is a peg.
I just put a nice weld in there for mine, you wouldn´t believe all the money i´ve saved on chairs since then.
You think off the shelf are awful? Try eBay hip replacements! :-0
At work i see tons of them, but they are all used and slightly burned
I can no longer get replacement parts for mine... What a cash cow!
"In the interest of saving time, the shop foreman has already reamed your bung."
OMG, I'm dying laughing...
There is nothing funny about saving time!
I always absolutely loved those super duper clear training videos that explain every bit of what you are doing and i know you did it as a joke but that was incredibly helpful. Thank you.
I managed an implantable pump project some years ago. It included a Ti bulkhead with complex machined spaces that provided mounting surfaces for electronics, a peristaltic pump head, a stepper motor, and valves. It was CMC machined on a large block with 32 blanks on each of its 4 sides in a lights out facility. The tool speeds and pressures we so high that the metal was almost liquified ahead of the tool The CNC machine was a large as a single car garage and the process was amazing to watch. The tool magazine contained various configurations of formed tools and relatively standard cutters. The machine knew the longevity of each tools and replaced them in the library with new ones when necessary. This started my interest in machining.
I’ve actually never used a vernier caliper, I’ve always been a dial caliper kind of guy. But I gotta say, that quick primer on vernier caliper use was darn insightful. Thank you for that!
Ugh. The only times I touched a vernier was for re-qual. Not a fan...
DesmoFan I’m not a machinist myself so a dial caliper has served all my purposes in the past. But I still consider it fairly useful info if I’m ever forced to use them.
@@chris15252 oh, totally. dial calipers are great :)
My 6”,8"’, and 12” calipers are dial. But I have a 12” and 24" vernier. They are accurate if you know how to use them.
@@whiskeytangofoxtrot4363 6" dial, and my scale, everything else was micrometer. Calipers are certainly handy! I often wish I had one at home. I've just never bothered to pick one up xD
Like many others, I appreciate you showing us how to read Vernier calipers. Thanks!
As someone who _has_ read verniers before, I'm glad he showed us how! Half the time I've had to use a _ruler_ to get the course measurement!
Maaaan those vintage videos were pure gold....
Awesome video! Fantastic throwback inserts! The vernier caliper lesson was spot on!
I actually didn't know how to read a set of calipers before today.
Loved the 60s vintage army training film look. It was like being transported to 1971, living in fear that Drill Sergeant Smith would play a "joke" on us again by lobbing a tear gas grenade at us as we stood in formation. Good times!
Those retro bits reminded me of a couple shop films(it was on Betamax I think)...
One was how doctors will use a magnet to remove metal bits from your eyeball.
The other was table saw safety showing what happens when a 2x2 is being ripped and is launched into and through your torso.
Ahhh, Shop Class
Man. I love this channel. I’m here because you left a comment on AvE’s channel! Currently watching you’re entire back catalogue. Great content Sir.
Your videos are great.... both informative and fun. Great work! I do no milling or machining myself but watching you turn metal chunks into finished products is oddly satisfying.... That's it... I am buying a lathe!
On today's show, This Old Tony makes titanium tinsel for Christmas.
Tune in next month, when he teaches us all how to destroy brand new drills, quick and easy!!
@@roadkill5333 I don't know. You need a real pro for that kinda work. That's something you go to your local high school shop for. Those guys and gals know nothing more than destroying hundreds of dollars worth of tooling by looking at it wrong!
I'm not a machinist, but I love the editing style, the wit of your narration and the precision that goes into these things. Nice work.
I was just reminded by Aaron of the flask occurrence! Not only are these Tony videos fantastic learning tools, but it reinforces Tony's ranking of "Master of Ink cap" within the writer's guild. Really great video!
That primer on the calipers was awesome. Insightful and hilarious as always Tony. Thanks for the video.
Absolutely brilliant! One part H and two parts S!! Technically fascinating and comedically amazing!
Man, I really enjoy your videos. You earned the "Bell Icon" (and I don't give that thing lightly).
Thank you.
I just set up follow on Patreon, works fine
Same here - in fact only AVE and TOT does have this privilege :D
I’m only 16 years old I’ve been watching your videos non stop man I could watch this stuff for days you just have this way of explaining this so much better than other videos and other creators
Simply amazing video man. And honestly these videos you make are top notch
The worlds productivity must take a nosedive when TOT posts a new vid.
Followed only by increased laughter and greater productivity, that is after everyone returns from thier 20 minute bathroom break.
Tell my wife that...dinner still ain't ready and she'll be home in five minutes!
@@davidsmart8594 How is your wife going to make dinner if she isn't home yet? I don't get it.
@@thatguythatdoesstuff7448 ^Applause!
OMG...this is the best yet video from TOT....I laughed till I cried..your editing skills are just as amazing as your millwork/lathework is!!!!! 10/10!!!!!
Impressive knowledge, and some serious comedic chops. For a while I had no idea what I was watching exactly but I was loving every second.
Turning Titanium; this will be fun! Rule one on Titanium is get in and then out quickly. I use coolant hole drills for long holes in Titanium.
BRILLIANT OPENING! Your, dare i say cinematography, is on point!
you mean it´s dead nutz?
Love the futuristic look in the intro 🤪
Amazing editing, Tony! Love how it looks like an 80s vcr tape ❤️❤️❤️
I always learn a lot from your videos but this one has been by far the one that made the most sense.
I still have my shop class surface gauge! found it in the attic with all my baroque oil paintings from kindergarten.
Why arent they on display at the modern art museum?
@@eoinkenny3188 Because he made them in kindergarden.
@@moth.monster So they don't qualify as modern?
8:36 for Titanium I always use HSS-E drills, after I burnt a normal HSS drill much like you did up. With the Cobalt you can easily use it up to 450°C without a lot of damage.
Even though they cost about twice as much, they are certainly worth it. Especially when you want to drill everything with a single set of drills.
Seriously? Twice the cost is still saving me money, since I go through 2 drill bits on each friggin hole. I'm going to find some good HSS-E bits and try them. Thank you sir.
I didn't realise that anyone was insane enough to try using HSS on titanium in the first place.
I have a few HSS-E drills that I use with stainless steel, they're great. However I'm unable to get odd sizes locally, I currently need one for pre-drilling holes for cutting M5 threads.
@@Shaun.Stephens Try McMaster Carr. You can order almost anything from them
@@etheroar6312 Thanks, I would but I'm not in North America and even if they deliver here the postage would likely be crazy. I dare say I can get one locally but haven't got around to it yet as the job's for me so isn't urgent.
"It's a gas cap, for crying out loud, not an ICBM nosecone." *snort*
“In the comfort of your own bathroom”, literally gold.
Holy cow. I now know how to use calipers properly. Our teacher tried to show us how to use them with an ancient video from what looked like the 1990s that didnt have audio. That was the reason I bought an electronic calipers. Now I can finally use analogs too! Awesome.
Ancient video from the 90's..LOL! I find that hilarious because when I was in school in the 90's, we watched telecine VHS tapes. Videos that were made from a camera pointed at a screen showing a film. The old army films were the best. Had that great narrator voice. Search YT for "how differential steering works". You'll see a similar film conversion with an excellent explanation of how something works.
I didn't see Abomb in cut offs!! No I didn't LMAO. Thanks for the giggles and the great "Tape #21".
I hope adam seen this. Lol
I watched this video around the time it came out a few years ago and the “job shop cutoffs” joke has stuck with me ever since. Absolute gold. 👏
We have to be able to read vernier scaled instruments for our A-level physics exams in the UK, some of my class mates don't understand them and your explanation is the best I've heard. I will be showing them this video.
12:07 That sand paper made my girlfriend ask why I was rolling on the floor
That noodled-out-videotape look was amazing, and the style and tone were spot-on for ye olde educational videos. It also reminds me that I have several large boxes full of VHS tapes which I have not used since I last moved house. More than 20 years ago, come to think of it. That actually makes me feel quite old, and a bit sad.
Loved this! One of my favorite This Old Tony videos ever
Vermeer was a Dutch Baroque Period artist. Vernier is a method of subdividing linear increments invented by French mathematician Pierre Vernier. And the next thing we hear will be the sounds of TOT being fitted into Abom's Monarch 6-jaw and having his bung threaded.
i believe the 6 jaw is on the victor lathe rather than the monarch
And these days Vermeer is a company that makes tree chippers and hay balers. :-)
I think I know who will be the Victor!
I learned ALOT from this! Now! The Future!! Abom does modeling on the side.
TOT. Thank You! Made a simple (very) titanium wedding band for my wife for 18 year anniversary. She's an active woman and keeps losing stones from the engagement and wedding band. She wanted something tough and streamlined. Watched this vid maybe 4-5-6 times before i chuckled the rod in the lathe. Kept having to rewind, i was laughing so hard. "Reamed your Bung". Classic. Thanks again for sharing your talent, humor, and expertise. Btw, she loved it. Bonus points for Hubby
Jeeeeez! I actually felt my head hurting!! That calliper explanation was incredibly well explained. Good work Tony ol’ chap, good work!!!!!
Hey Professor This Old Tony from STF University your lessons on internal thread, vernier calipers and high speed steel were amazing.
And really liked that other type of job shop cutoff.
OMG.... Love from TOT!!!!!!!
Mate, it’s 5:00am in Australia and I’ve got work in 4 hours....what are you doing to me? I’ll only have time to watch this video a couple of times before I have to head off.
Rapidpanda1st legit 😂👌
Same. But I can share with everyone on the bus. Ill be sure to turn up my volume, and laugh out loud at the appropriate times.
Everyone deserves to listen to TOT.
I’ll do you one better: Western Australia :’)
Based on my limited inactions with other Australians, being that you are awake at 5:00am and have work in 4 hours you’re most likely drunk. Please understand my assumption is based on my high regard for Aussies. Cheers!
Lol who tf goes to work at 9 am?
Love the closer.
Especially the "colorful" ending.
absolutely loved the theme of this video, keep up the good work tony
There needs to be some type of an award for the best videos on TH-cam. TOT would definitely win in all categories.
Not if TH-cam has any say in the matter. That award is reserved for someone like Taylor Swift.
Today I finally learned how to measure on calipers I already own 2 pairs of.
John Possum: Good! Now start marking out stuff with the tips of the calipers, so that you no longer need to pay attention to the vernier's markings.
I see a lot of people posting this suggestion.. surely thats a terrible idea as its a precision instrument? or has the joke gone over my head lol
@@CactusforceX I believe it's considered caliper abuse. Wouldn't work with mine anyway as they are plastic. Turns out the joke is on them.
Literally the best videos on the internets. Tanks Tony!
Dude, your videos are hilarious and very educational. Keep up the good work. Love learning in this fashion.
Well Tony, it was nice knowing you. Once Adam sees this vid, I have the feeling a very large wrench is going to interface rather suddenly with your cranium.
ABOM torque on its' way!
I'm putting my odds on a really large tap handle...
I appreciated the style. Reminiscent of science instructional films from Welcome Back Kotter. Tell your buddy to weld his ti parts together, clean and anodize at 25-30 volts for a nice blue /purple ( blurple- for those in the anodizing biz) Nice work as usual TOT!😃👍
Having edited at least -two- videos in my life I appreciate all the effort you put into adding the little extra gags into your videos.
Great video! Loved the Abom plug!
I just want to say that your VHS tape makes for some seriously awesome shim material. And that's more than I got out of my master of engineering. :D
