Turning Stainless Steel Bolt into Useful Pneumatic Tool - Air Graver without Lathe Version - 2

In this video, I turned the stainless steel bolt into a pneumatic air graver. This tool is often used in jewelry work for doing engraving stuff. This is an absolute hell of a build. In past, I made the first version of air graver but for that, you need to modify the car air compressor to use the graver. I would say, that type of graver is far easier than this one because there weren’t too much-complicated parts in that one but this version consists of so many different small parts. Making this tool without a lathe is definitely a challenging task and if you go a tiny bit off then the tool is not going to work at all due to this, I failed two times in making the piston absolutely right.

I almost ended up giving this build but a little boost helped to give it one more try and it worked as e
