- The mission to run the engine for longer continues... this time I fit a rad and associated pipework...
Warning - this video contains Maths! (Math if you are in the US of A...)
WAIVING A HAND FROM WEST VIRGINIA US. LOOKING forward to seeing 👀 it Run again. You have pretty nice welds there brother. God BLESS EVERYONE AND TRUST IN OUR LORD AND SAVIOR CHRIST JESUS 🙏.
Fascinating, and great to watch, study and learn from. I just about hung in there with the maths😂. Brilliant work!
Thanks for hanging in Tim! Next episode will definitely have less maths and more noise.... (I hope)
Great work, top marks for doing the maths on the cone, 90% of us would have winged it 😂
Thanks! But that's probably enough maths for a while now!
Great stuff Chris. Watching on a Saturday morning drinking my coffee is a great way to start the weekend - now I just need a bit of motivation to get into the garage or maybe I’ll watch Shed Racing for an hour 🤔👍🏻
Off into the garage you must go!! (and make a video while you're at it...) :-)
It’s all in the plan 😉
Loved the arithmetic Chris, I do enjoy putting the calculator away and engaging the brain to keep it ticking over. Nice work too, looking forward to the flush and next engine start up 👍
@@leighharron cheers Leigh, I too am a sucker for a good puzzle.. which is what the whole project is!!
That is going to be so cool! Oh me, the maths! 😱 Oddly enough. I just made an insulating sleeve to fit a McD's small coffee cup. I turned to an on-line calculator for truncated cones. The calculator did all the head scratching for me. 🙂 Now turn your talent to calculating the flow produced by the pump and the flow capability of the radiator. 😵💫 Twas a fortunate stroke of serendipity that the rad frame aligned with the wagon's.
Hi Chas, I’ve just done the flow calcs and the result = ‘plenty’ 😉.
@@thebracketfactory You are way ahead of the curve. Obviously invoked Euler's Identity. 🥰
I laughed out loud about Anette! Shame she's not been used this time. Outstanding work as always, love a bit of maths, but then I would being an engineer 😉
@@The_Cotswold_Engineer glad it made you chuckle! Watching the clip made me chuckle!!
Your work is wonderful! I love your attention to detail.
Looking forward to the rest of your build.
Thank you!
@@BGreat2 thanks for tuning in 👍
You would have better better off parking the maths (sums😂) and learning a bit of pattern development. Truncated cones pretty easy to do, and you could have had your angle change and reduction in one go. The elbow is an even easier development since with a cylinder all the heights in 2d are true lengths unlike the cone where only the outer lines of a 2d elevation are true lengths. (Yes I am a sheet metal worker by trade). When making these sort of bits with the gear you've got I suggest making in two halves, an extra run of weld granted but much easier to form. If you had pattern developed them the diminishing lines would have given you a nice guide to incrementally tweak them round. Anyhow, good job, on the top hose at least😂😂! Looking forward to seeing the longer runs and getting the settings dialled in though I suggest you make some exhhaust gaskets before you do. If it survives a few heat cycles without blowing will you leave the heads on?
@@blackhouseengineering5386 there is more than one way to skin a cat, but I bet your way is better ! 😂. I’ll have to do a bit more research on pattern development… thanks for the tip 👍
@thebracketfactory Very true and you got the job done which is what counts! When I were a lad the bible was A. Dickason's book Sheetmetal Drawing and Pattern Development. Probably long out of print but there is plenty of resource on the Interweb. The real old hands when I was an apprentice would make simple "sculpture" by tacking welding rods together then roll that out on the sheet marking where it touched to produce a surprisingly accurate pattern. They called it a RolypolyOgram and could do it faster than I could draw it🤣🤣
Excited to see the next start and all the bells and whistles you are attaching for monitoring purposes. Nice work :)
Cheers, I'm itching to start her up again!
Thanks for the Maths lesson...brought back good memories. It is Math in Canada but I'm okay with using Maths as well ;-)
Thanks! But that's probably an enough Maths for a little while now!! (Hope to have a lot more NOISE in the next episode....)
Great skills. Love the Maths ❤️
Real progress thanks Chris.
Thanks David!
I enjoyed this episode and the math lesson. I also enjoyed math in school, and those were some nice pieces you made. That engine is large and so is the water pump. Keep an eye on the flow thru the rad as it may stress it out. Otherwise, I liked the way you cobbled it up. Good Show and looking forward to seeing it run. Cheers!
Thanks Jorge.. yes, that is a hefty old pump isn’t it… will be interesting to see if anything wants to go ‘pop’ (or squirt) when it is revved higher…! 💦
Excellent welding 😊
@@martinhacche1329 thanks Martin 👍
I think I might have gone for modifying the radiator but that would be the more risky route, in the unlikely event that you find the flow is restricted you still have that option.
As always you have done a great job and the maths was interesting as it showed how to create a cone that was a perfect fit.
@@grantbaker3336 thanks Grant! I might invest in a cone roller now…. Maybe! 😂
What would I have done; asked you to do it most likely! Another great watch ...
Thanks for tuning in again !!
Great vid as usual. I can't do the maths, I'd have just ditched the 60mm outlet and made a new base plate with a 32mm pipe all the way to the hose at the radiator. Keep up the good work.
I didn't actually think of that! But I'm afraid it wouldn't work as the thermostat is housed between those two flanges, and like everything else, it's a whopper!
Australian here, we speak the Queens English
Not the Kings? 😂😂😂
Proper engineering. Nice job!
Cheers!!
Sunday TH-cam catch up.
Just watched your mate 'Oak Swamp', now 'The Bracket Factory'.
What a contrast, but both building cool cars. i think I favour your approach but glad you could help Bryan.
Any news on a Chassis?
Cheers Chris! Yes, we are very similar but very different at the same time! I do have a potential chassis but the chap 'letting it go' is going to let me know... keep everything crossed!!
Fantastic work. Love the maths.
@@nigeltoon1848 cheers Nigel, though I think I’ve split the audience with the maths… it’s a bit ‘marmite’ !
@ Disappointing that people tell themselves they don’t like/can’t do/don’t see the point of maths. It’s fundamental stuff.
Chris, the tee-shirt arrived this afternoon. Thank you. I’ll look forward to some tee-shirt weather so I can flaunt myself round the neighbourhood!
I’m not sure of the sizes, but you might like to see if you can source some radiator top-hoses from a Bedford CA van, they start large (thermostat-sized) at one end and ‘radiator-sized’ at the other.
Your maths example lost me at the first line, but never mind… both my bikes are air-cooled so I don’t need to make radiator hoses!
Regards, Les
@@leslieaustin151 please email a selfie Les!!
@@thebracketfactory whaaaat? You sure? !!
OMG Trig and Algebra gave me nightmares at school (65 odd years ago ) or as dear Physics beak used to say '' lets do the sums'' but as I have a huge box of old copper Yorkshire fittings I would have made a new flange for the engine output and used copper pipe and fittings to suit whatever the rad stubs were diameter wise. .. If you ever get to see my old Dodge truck you may notice said bits of copper, cool content as usual and look forward to seeing some steam and water everywhere next time.
@@bryansaull7554 got a feeling there will be a lot of steam and water..! Thanks for tuning in 👍
Loved this video -Thank you
Cheers Ian!
Great work Professor Peach :)
@@ashleybragetti2199 😂. Thanks Ashley!
Great stuff...
@@peterbonnez thanks Peter 👍
Yes Australia = maths.....WOW those equations spinning my head out....hahaha GO LA FRANCE...GO MR BRACKET
Cheers Rob! 👍
Great maths and working with what you have, I’d have just bought a bunch of elbows and a reducing hose from eBay.
@@H1WEX got to admit I was tempted to… !
glad you chose the linda radiator as its a pressurized radiator the other with the larger header tank looks very much like a non pressurized non water pump or thermostat thermo syphon cooled system same as my austin ten. Thanks for the update this is going to be a great project bulid .
Cheers Paul, thanks for tuning in!
Thanks Chris, happy to see you used some "brackets" in your math(s) equations, oops double plural.
haha, I see what you did here Lance!
The section with the maths is what tortured me for four years at school.
Sorry! 😂
Agreed, horrible memories of blank incomprehension whilst being left behind by everyone else.
Thanks for sharing. You need a tee shirt with all of your cereal box scribblings. I bet you'd maybe b sell one or two. 🤣
@@argee55 actually new T-shirt design is in the wings! But not those scribbles… 😂
Impressive 👍
@@paulhewitt1488 cheers Paul. 👍
All that faffin with the maths and 50.5 degrees just pulled out the air with no explanation 🤪🤪
sorry about that! I thought I was probably starting to get a bit boring... but here goes. Theta = C1/R1. We have already calculated R1 (114.3mm) and we can calculate C1 to be 100.5 mm because we know the diameter is 32mm (so it's just 32 x Pi). So theta is 0.88, but that is in radians, not degrees. So given that there are 2 x Pi radians in 360 degrees, we can convert 0.88 to degrees by multiplying 0.88 by 360 and dividing by (2 x PI) to give us 50.5. Probably should have just rolled up some card in hindsight !!
@ aha, okay, got it now, thanks for the reply 👍👍😊
Hey up mate you asked the questions so, waste of time on your passion for the water pipes as you won't use them in the car, rad is fine for now but still won't be used in car, can't remember your other question's but was a good video and i enjoyed it
You are right John... complete waste of time really but I *sort of* enjoyed making them! Glad you enjoyed it anyway :-)
@thebracketfactory nice one could tell you were enjoying it I've been known to do similar things and yes is does feel good, like I said was top video mate
Ah, transposing equations. Takes me back to electrical principles at college. Shame I didn't retain any of that information 😂
I confess it did take me a while to drag that maths from the depths of my brain!
In Australia we also say maths, but to be accepted as reliable the drawings would need to be done on the back of a beer carton !
@@johnrebus1641 😂
Proper job (The Maths made my head hurt) I was good at Art at school, but maths can do one!
😂. Glad you liked (most of) it!
@@thebracketfactory I liked it all Chris!
I’m like the equations 👍 I’ll use that👍
In NZ we say maths but Americanisms are creeping in. I think most people would miss the Annette reference. Even more obscure, the actress who mentioned it was Granny in Metal Mickey. I think Fusion 360 has a feature where you can make a shape in 3d as sheet metal then unfold it to get a flat pattern. As someone else mentioned I would probably just have rolled up the cereal box by hand to get the right shape then used it as a pattern to cut sheet metal!
I'd completely forgotten about Metal Mickey!! Yes... maybe next time I will just roll up that cereal box!!
I’d like to see your explanation of this type of development in practice 👍👍
Not sure what you mean Martin?
@ Hi, there was a comment made by an earlier person (panel basher who stated a different method of construction of the conic section. You showed a mathematical method to achieve your conic section and then constructed it on video (brave) our panel basher only made a comment and I’d like to see the way he would actually achieve the finished article 😊
I usually roll a piece of paper like a ice cream cone, adjust one end of paper to diameter of large pipe tape it then roll other end in or out to fit other pipe tape then cut. Maths is not my subject.
I might do that next time Michael!!
Numbers, symbols, equations, a diagram… all I saw was a happy mouse 😉
We Aussies do more than one math, like our Brit cousins. We also solder not sodder and refer to RPM not RPMS, as well as have mudguards not fenders. We use serviettes and leave napkins for babies.
Haha, I’d forgotten about ‘sodder’!! 😂
I reckon disproportionately difficult solutions are the making of a good project, it's the polar opposite to a bodge. Not sure about the math(s), I didn't understand it at school but was sure I would never need it in life after school. Seems I was wrong!
Cheers Graham! (Though I might just roll a tube of cardboard next time ....)
I use frozen pizza boxes for my patterns! There’s a way easier way to layout cones right onto sheet metal that doesn’t involve all that math. I haven’t done it in decades but years ago I used to do it. I honestly don’t really remember it anyway right now!
Let me know when you remember Chris !! (I'm all for easier ways of doing stuff....)
Unlike you, Maths was my worst subject at school (more than 60 years ago) and you lost me before you started, but I enjoyed the fabrication. Funny, but when I use rollers I can produce cones when I'm trying to make parallel tubes. Best wishes.
haha - I know what you mean... I try and roll a tube and I get a cone!!
I should of paid more attention at SCHOOL😱THE MAD SCIENTIST IN YOU HAS MADE MYSELF AND OTHERS FEEL LIKE WE SHOULD OF PAID MORE ATTENTION😂well explained and totally baffling 🤪but perfectly MADE👍🍺
Haha… promise not to do that again (well not too soon, anyway..)!
You really have the engine sorted now Chris where to find a chassis with wheels ?,would you build one from scratch could be more cost affective or a donor XK 120 / 140 chassis
To be honest, I’d rather sweat a new fitting onto the radiator, bit of copper or brass rolled to a pipe, dress the end to a flange and solder it in.
When I swopped the 440 V8 in the Winnebago for a Ford Devon diesel I fitted the ford radiator pipe stubs to the Chrysler radiator, no problems despite the diesel vibration etc
yeah.... When I make the 'real thing' I think I'll do that! Cheers Paul !
@@thebracketfactory sorry for being offhand, and getting awkward. You’re a much better engineer than I, and more balanced.
Thanks for the build so far, I look forward to seeing more, and I’ll calm myself down from my day before commenting.
Regards Paul.👍👍
Just brought back memories of being back at technical college 😁
Nice work but I think I'd have soldered in a bigger spigot as it would have been simpler.
I wonder how Brian from Oak Swamp would have done it? For sure it would have involved big hammers🤣
As it's often said, many ways to kill a cat.
Thanks for the update, have you found a chassis yet?
Cheers Colin.. I hope it brought back good memories! Not sure what Bryan would have done, but I can guarantee it would involve an angle grinder and it would be ingenious!!
Very good but the MATH bit was a bit heavy and there was a distinct lack of banjo playing. Perhaps next time we can have a strum.
@@joan4906 i did warn you!! (But I promise no more maths…)
Sorry… Math… 😉
Who is theta.? Whats the ratio? Other than that a good watch :-) i ended up pretty much binge watching all the previous episodes to catch up after YT said you might like this....cheers
@@excossack Theta is Anette’s sister 😉. Thanks for tuning in 👍👍
Nice work Mr. Factory. Would putting 60mm pipes on the rad be an easier solution? Since flow is proportional to the square of the pipe size and the engine's inlet is twice the size of the rad's it's going to want to flow about 4 times (Math as we say in Canada) as the rad.
@@jonnyb2532 that would be waaaaaay too easy 😂.
@@thebracketfactoryI have a feeling this video was produced in the lull just after new years celebrations and is recovery medication
@@johngibson3837 😂
First time I've been first like and comment 😊
Is the outlet so big because the engine pumped water for the fire engine ?
I'm going to guess that "Annette" is a The Italian Job reference
@@crispindry2815 bingo ! 👍
Sence this is not going into a fire pumper, the cooling system and water pump can be down grated to the original car system ?
Yes, I don’t think it’ll need to be quite as heavy duty as a the one in the fire truck. 👍
Well I never thought of that so we're evens then. Any luck finding a chassis yet?
I had a lead, it went cold, and now it has warmed up again! I hope to report good news soon.... keep 'em crossed....
You lost me when you got the cornflakes box out and wrote on it, why not just roll card up and cut to size. Or instead of a cone reduce the inlet on the engine therefore having a top dog at a better angle…. There again great job. And very nice work
Good suggestion in the engine outlet Brian, but it is also the thermostat housing so I couldn't do that. When I come to build the 'real thing' I think I'll just up the size on the rad... (whatever that Rad ends up being !)
We call it maths in Australia, fyi.
Good answer Andrew!!
Maths we say in Australia
Good answer!!!
I would have ditched the maths and made a cone etc out of cardboard !
haha - i might do that next time!! (If there is ever a 'next time'....)
You know stainless steel elbows and reducers are cheap and plentiful on Ebay?
Given you have a million other tasks to perform it may be a better alternative than messing about making cones and mitre boxes.
You have a tig, welding stainless should be no problem. Just make sure you purge the tubes with argon.
Thanks for the tips 👍
@@thebracketfactory if you have not purged tubes before, just tack the tubes, bends and reducers together lightly, then tape up both ends of your construction with masking tape. Punch a small hole in the tape on one end ( 1/16") to allow the gases to escape and on the other end make a hole in the tape to fit your argon hose. Argon flow should be about 2 to 4 litres a minute. Use 316 stainless wire. You can weld quite well. You will find this as easy as pie.
@ ok, so i’d need to another regulator/feed from my welder? Not sure if I have a provision for that..?
@@thebracketfactory put a "Y" fitting on the outlet side of your regulator. Add a flow control valve to the leg of the Y going to your purge hose. That will control the flow into the tube you are welding. Once you have purged all the air out you won't need a lot of flow, like I say 2 to 4 liters a minute depending on how long and how big the tubes are. Get the flow valves that have a glass or plastic tube on them with a small ball inside. As the flow increases the ball rises in the plastic sight tube. Welding suppliers have them.
@@Hydrogenblonde ah yes, of course, thanks. I"ll get myself another regulator and set that all up! Thanks again!
All that math, could have used bends instead of right angles, enjoy the vids, crack on 👍
cheers Joe!!
Can't it go anywhere you want?
You mean the rad?
Sorry, you lost me at R2D2. [there, ended the lesson!]
Haha, I think I split the audience with the math!!
Never put on a electric fan with cable ties. It might be easy but it will destroy your radiator.
Good job I couldn’t then!!
Is the outlet so big because the engine pumped water for the fire engine ?
Yes and no...! The engine did pump water, but only by driving a separate water pump...so the engine would need to run continuously at decent revs while not moving... so had an ENORMOUS radiator and BIG pipes connecting it all up!
