Transforming A Stainless Steel Bolt Into A Fully Functioning Miniature Lathe Chuck

Small projects aren't often the easiest. I had the idea of making a fully functioning miniature lathe chuck from a single stainless steel bolt in mind for quite some time. I already started with machining the first parts quite some time ago. But other projects had to done first. So a few weeks ago I remembered this project and continued on it.

Except from the brass inserts which held the screws in place, everything on this chuck is made from the one M18 bolt you see in the beginning of the video.
It was quite thrilling to machine this piece with tiny and sometimes special tools. The pars are tiny too and a lot of options to fail.
After recording over 160GB of raw data on this project I finally got a fully functional miniature lathe chuck inspired by Röhms 260mm faceplates/four jaw chuck. Scale is 1:10 with a diameter of 26mm in relation to 260mm from the original chuck.

I hope you enjoy this episode. Let me know what you think in the comments.
