Most hydraulic jacks are big tools that can lift upwards of 1000 kg but [Maker B]’s is quite a bit smaller than average.
The world’s smallest hydraulic jack is a tiny hand-machined model made out of tiny pieces of iron, brass and copper. But here’s the kicker: It’s a real hydraulic jack with real hydraulic fluid! At 1/5th scale, it obviously isn’t as strong as a full-size jack, but it can still easily lift an impressive 24 soda cans! Switching between the lathe and mill, [Maker B] shows how all the parts of the jack are made from stock metal in detail, and even explains in simple terms how a hydraulic jack works in this masterpiece of a video.
Over the years, we’ve seen plenty of tiny objects cranked out from stock pieces of metal — often bolts. But the fact that the end result here is a working tool, puts it into a decidedly less common niche. Of course, given what we’ve seen from [Maker B] in the past, it’s hardly a surprise.
