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&just hammer the pin out, i had to drill them out. I didn&drill exactly in line with the pins, that&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...
