1930s German Spiral Jack Restoration - Bilstein 2500kg. In this video i'm restoring a very old, super rusty and dirty german spiral jack. It's a Bilstein from the 1930s, it can lift 2500kg. Like, comment, subscribe. I found this spiral jack which needed a restoration desperately. It was super rusty at the bottom and very dirty in general, the top part was bend, but it was still working. So i started with disassembling, what turned out to be very tricky. I was struggeling quiet a bit to get the gear wheel of the shaft because it was locked on it with two pin connections. They were both blind, so i couldn't just hammer the pin out, i had to drill them out. I didn't drill exactly in line with the pins, that's why i needed to drill several times and the holes were not round anymore. The top piece was forged on the shaft, so i first removed the holding material with my air die grinder. Then i was able to hammer it of the shaft. I removed the rivet heads on the bottom with my angle grinder. Once i had everything in pieces, i started to wash them. Some pieces i cleaned with sandblasting. I grinded two small pieces clean with the belt grinder, to remove rust and old paint. Same with the square head of the shaft, i welded the holes in it and made it all round and smooth again with the grinding wheel, file and scotch brite. I made the same with the gear wheel, but first i needed to remove the old pins and drill them out. After that i welded the holes, smoothed the welding with the file, cleaned the inside with reaming and cleaned it all with the steel brush. To restore the top end connection i first bend the big piece, made the back flat on the mill and then turned a new section which i will later press on the shaft. I also turned the the shaft on the lath, made the same section on it and cleaned the front side. I hammered the disc flat with the hammer and turned the same diameter on the inside. Once i had that, i was able to put them all together, line all 3 pieces up with the old hole and drill that one up again on the mill for a new pin connection. I forged that top end back, so that all pieces hold tight together without slack. I drilled out the old rivets from the bottom. Now it was time to paint. As the paint manual says, i cleaned the parts with water, but as soon as it was dry it started to rust again. That's why i covered the inside of it with grease. I painted all pieces twice with 5 hours in between. When thge paint was dry, i started to assemble. First i put the cover over the spiral, screwed the gear wheel on it and locked the thread again with a weld. Next up i pressed in the square shaft in the other gear wheel. I drilled one hole for the pin connection, hammered the pin in and then i repeat that for the second pin. After i placed the bearing i put the spiral back in the case and i mounted the cover with the restored 3 screws. I put the piece with the spring in the hole of the back, put the little painted cover piece in and fixed it with another pin. As the last step i mounted the bottom cover with two rivets, unfortunately i forgot the press record on my camera, so there's no footage of that. And last but not least i painted the text white, so it stand out very nice. It was a tricky restoration with a lot of machining. Sorry for my bad english, it's not my language.

Ac 260 : If I caught this man in bed with my wife I’d tuck him in.

Ace Strife : No wonder this guy restores things so well.. he has 4 arms! 12:41 ;p

Guy Grundy : Aside from the undoubted skill and craftsmanship on display,the thing that I find so impressive about these videos is his ability to deliver a clear visual narrative via his filming and editing.

Iron Dragon : Me: oh my god I love the sandblasting parts Video: *completely skips to them being clean*

Toothpaste Boiii : true asmr without annoying music. what a legend

lovegirls1970 : For a guy who restores rusty oily tools his hands appear to be callous free and nails perfectly manicured.

Sentinel Mallus : What i like is there is no "I'll add my touch mark" it is all "I am restoring this to the original makers former glory"

Gabriel Csaba : OK, I am now officially addicted to your channel. My dad used to have a shop with lots of ancient tools and machinery, typically kept in working(ish) condition but badly soiled and knocked around. I have never seen some of these tools in the pristine state you leave them, and I can't believe how beautiful they are.

Maor Mama : By far, the best restoration channel on youtube. No dumb music. No pointless talking. High mechanical skills. Great editing. 11/10.

Clark Khoury : i love these videos, but it would be so cool to see the thing function at the end also :)

Core : what is that cube with spring for? Some kind of safety?

Doug Rakocy : Ron Swanson approves this video. No nonsense + Excellent Craftsmanship

BookofIsaiah (Matt B) : Awesome restoration!! Thank you for sharing your talent with us all !!

Peter Nice : The Steam Locomotive preservers in the U.K. would love you to pieces....they take rusting hulks that are in many cases 60 to 70 years old and ‘make them new again’. Your restoration work is superb!

Gregory Luckert : Thank you for your excellent videos. Your filmmaking and mechanical skills combined make art. Thank you again for sharing.

relativeair : Another gorgeous piece!!! Do you sell them? And if so where can I find?

Kevin Ryan : Ridiculous... Anyone with decades of experience, talent in metalworking and $50,000 worth of equipment could do this!

skaiidawg : @my mechanics great work. Just a tip, when you hammer something straight or bending and you are using your vice, always bend it towards the fixed jaw. Its stronger and you will not damage your vice.

John Nordic : Watching this is kinda therapeutic

breezyjr : I had to finally subscribe... I simply cannot stop watching these videos... And, I know I'm going to reach the end and cry cause I watched them all... lol
