I can't remeber the name of the person who does the translations, but you are by far my favorite translator. You don't just translate, but you are able to translate tone of voice and sarcasm and such in a way that is easy to understand.
@@SwapBlogRU dude I would've never watched these without your voiceovers, I'm far too dumb to learn another language but I love the content. keep up the amazing work, you literally bring my daily bad ideas to me in watchable form haha
Idea: Find an engine that has been sitting out in the weather forever (like only a block with a rusty crank in it) and put it together and see if it will start, no cleaning or anything, only free it up so it can spin.
When I was 16, I rebuilt the engine in my first pick up. Had it all apart, had to lap the valves, the head was OK, bearings, rings, seals...yada, pretty well a complete overhaul. I grew up really poor, not much help many times, before googling something was an option. Actually going to the hardware store and asking was the way to get a fix-it guide. Some of the stuff you guys do on this channel for fun really remind me of things I had to do for necessity. I think if more young people tried to tinker and fab like this and found joy from making/rigging/tinkering, and less from zombie screens, we'd have a better world.
My local machine shop had a giant belt sander just for surfacing heads. Not milling them, just removing a couple tenths to get em flat. The machine was stationary, like a table, and the belt went round and round like a conveyor belt. You'd just hold the head down against the belt, and check it every few seconds.
I planed and level this set of Harley-Davidson jugs by scraping them on the concrete floor. The guy looked at me like I was absolutely nuts. He was so worried about it, he took it to the machine shop and had it mic'd. The guy told him, whatever this guy is doing let him do it, cuz this thing is pin straight. The main thing is to keep it flat at the beginning and end of the stroke.
Had they rubbed some sandpaper on the cylinder walls for a quick homemade hone those rings would have worked much better. Funny seeing them talk about twisted heads when the one on my Volga was like twice as twisted as theirs.
The only problem here is that it cost more money to set this up in time and sand paper then paying a machine shop 30$ usd... ive spent 50$ in sand paper doing this waiting hours, when I coulda just payed 30$ and been done.. I've learned my lesson on this. It is possible if u have a glass or metal flat table already and free sand paper.
teaching manual labour in american school ? oh no biden and his voting minion lefties wont like that, theyd want the illegal aliens todo the rough mans job
@@girlsdrinkfeck I'm in the middle, a little lefty on some things, and righty on others. I hate how art, music, auto shop, wood shop, welding, etc, are disappearing from high schools, yet they always have money for sports. And they drive me nuts with all that PC "woke" shit. You can't even tell a joke or compliment the opposite sex anymore, or say "Merry Christmas". Sheesh.
These days you go to community college for that. I'm learning welding RN and I'm gonna make some stacks. Next door is Autoshop and down the hall is horiculture.
@@donellmuniz590 In reality, i feel that the russians have been dealing with some heavy changes since the soviet union fell apart, and when times get tough families stick together, where as here i think the homeless problem is because we have had it too easy in amerika, and have forgotten how to rely on our families, and most people in the country are being raised by single mothers.
ring gap isn't that important for compression alone the reason the compression is shit is because piston rings usually have spring properties which these homemade pistonrings do not have
Actually, you are quite mistaken there. When sub-thou's tolerances are required, no machining can deliver that. They will need to hand scrape those parts. Tracks on precision lathes being a prime example.
There only one thing I would of done differently is turned the head 180 degrees half way though coz the motor might have put more or less pressure on the head
@@Iaintwoke I think cast iron would be to fragile for the rings. Pistonrings need to be flexible, they expand in the compression/work stroke due to the pressure in the in the cylinder.
Cheaping out on rings is a bad idea. They cost peanuts for that engine, much cheaper than machining them. Sand paper deal is an old old school trick and it's proven to work, you just need to check the gap with a straight edge
Bear in mind that in Siberia you have to make it through brutal cold weather to get to the parts store to buy those peanut-cosing rings. Why subject yourself to such torture when you have lathe and raw metal in your warm and cozy garage (54)?
@@AnalogDude_ my first one was on my totally souped up Kawasaki ar 50 and it made a huge difference to the power. It used to go 55mph on the flat really quickly.👍👊
You crazy Russian love your videos but I don't think it is your rings or the problem on this engine the resurfacing looked good but what about the valve job that head look pretty burnt up inside
Do you think you could get a engine to run without intake rockers like how some old engines did with really light valve springs? Atmospheric intake valve..
I have seen this done in the Czech republic using two twenty four volt windscreen wiper motor from a TATA truck one each end with storage heater blocks to level it and one on top for extra weight to ensure even movement.
Cool concept. Back in 1950, this was quite common to do. Interesting to see if one still can do so, or whether this art has been lost for ever. Actually, you don't even need the sand paper, you can use a scraper and achieve even better flatness. CNC machining ain't better, but much cheaper. I guess to fabricate a set of useful rings, though, more than one video would be needed😉 Looking forward to watching this video ! Edit : Having watched the video, I'll say you're nearly there. However, those rings are undersized, and you did not face them correctly. They need a slightly tapered facing. I guess the big issue may be the good, old problem of fitting new rings and not having the barrels done. Idea for next video ?
I love it, never say it can't be done, I think if had proper set of rings fitted it would run as normal 😀, I love the way you guys think outside the box, great video as always 😀.
Probably didn't need to go to the finer grit of sandpaper. As I understand it, you actually want a little "tooth" on the surface so it grips the gasket. Too smooth and it's easier to blow a gasket.
My father was an apprentice mechanic at the end of WW2 and he had some interesting stories about the techniques he learnt for repairing engines. Evidently he used to make piston rings using cast iron sewer pipes and he used to stretch pistons by bead blasting them on the inside. For the main and big end bearings he would cast them in place by pouring molten white metal into the caps and after roughly machining them to size then use a scraper to get the correct finished size.
Fixed many engines with a resurface like that including mine, i just put a thick glass sheet under and glue different sandpapers on it and move it back and forth, if you pull a string side to side and it doesn't have any gap and can see no to slight light when rests on a true surface it's alright as the gasket compresses for quite a few nm's, no need for a machine shop.
I think I would have gotten some Cast iron for the ring to be made out of other than that it golden the compression is a touch higher than stock great job Garage 54
Yes. Cast iron is the correct material, must not be so hard it scuffs the cylinders. Would also wear down and seal faster. Guessing they didn't care that much for the purposes of the video.
I like the glass and sandpaper method for achieving a nice flat surface! But you'd want to be _really_ careful trying this on a OHC engine. If the cylinder head has warped, the camshaft journals in it might be misaligned, resulting in a camshaft that won't turn after the head is removed from the block. In some cases, it's actually better *not* to resurface the head, as the head bolts can flex the aluminum head into shape when clamping it against the block, allowing the cam to spin freely again. But resurfacing the head while it's in a relaxed, bent state with a seized cam could ruin it...
So I've done the cylinder head thing..but man I was totally doing it wrong by hand..although it wasn't particularly warped more just needed some clean up..
For real we used to resurface our cylinderheads on our motorcycles when I was younger using a sheet of glass and wet&dry emery paper, also finishing it using grinding paste and the same meathod.
@@2lotusman851 Kinda worked, just needed to raise idle to 2000RPM once you get it started and manage the ridiculous amount of blow-by. Wonder if they remembered to set the ring gaps as far away from each other when they put the pistons in. Even brand-new factory rings will cause issues when the gaps are too close to each other.
I'm at the start and I will say I've done this with wet n dry sandpaper + WD40 for years works a treat just be careful. A full re-face? this should be fun 🍻
This was great. The windshield washer motor was just pure ingenuity. The piston rings probably didn't seal, because they machined them wrong. At 11:40 you can see the ring has a visible gap against the cylinder wall (not the end gap). This is caused because when the oversize ring was compressed during installation, it didn't retain a circular shape and bent unevenly. They should have machined the rings first to cylinder diameter, then cut the gap(with a thin dremel cutting disc) and then expand them. I think this would ensure that the ring is fully the round shape of the cylinder when installed. But also might be that mild steel will not work, because it does not have enough "springiness".
You should make a wood carving drive shaft for a car that would be a good 👍 idea 💡 I love ❤️ your video 📷 the are best ones and I can't wait for the next video 📷 #WoodCarvingDriveShaftForACar
ive got an idea only you guys could pull off, why don't u make steering wheel work the other way? it would be fun, and make a short circuit then let your boys compete in timed laps :P
This method definitely works! I have done it several times with a 100% success rate. Just use your hands, a flat sheet of glass and 120 grit sand paper ( it turns out that the slightly rough surface actually helps the head gasket seal better ). Use a sharpie to paint the entire surface ( that so that you know what has been scrubbed away ). When you slide the head back and forth do NOT hold it on the top. Hold it as close to the very bottom as you can. This will MOSTLY prevent uneven surfacing. Done correctly the set up takes about 30 minutes and the resurfacing takes about an hour.
The other way is to just make the paper spin under it rather than the block on the top. Can do this with a roller and motor on a wheel turning paper. Join the paper in a loop around the motorroller :P. Its also a super lazy way to polish and flatten other stuff. Can do it in a punch with a drill on slow with a band on the trigger pressing it down. Basically a DIY belt sander with whatever you want sanding sitting on the top.
If you just cut the gap the rings won't be round when they're compressed into the bore. A good 'garage' way is to make them close to the bore size (maybe 0.03-0.06 mm oversize), snap them to form the opening with no gap, then 'spring' them open on a mandrel and carefully (and evenly) heat the ring till it's faintly glowing red with a propane torch. This stress relieves the iron so they stay in the open state. Once compressed the ring will be much closer to round (though still not perfect). The ring can then be polished with sandpaper on glass and then gapped in the usual fashion.
I have actually seen a shop in the Appalachian Mountains where a guy had a grinding set very much like that. He said that he had worked heads, flywheels, & pumps on anything from a Massey Ferguson to a Big Block Mopar.
