Proxxon DB250 3 Jaw Chuck

Thanks for the replies… definitely do not speak Russian but do proudly speak some Ukrainian. The chuck in the video is completely different that the 3 jaw chuck of the DB250 but thanks for posting.

 

Certainly I meant to say that the towel over the chuck would need to be created in a tent in order to catch the oil on the first spin after applying penetrating oil.

Waaay back when I was much younger and in college one of our lecturers had a run in with a chuck breaking on a lathe - happened before I was there.

It hit him in the forehead but he was lucky, he was left with no brain injury and  piece of skull removed that left a large visible dent.

Fast rotating objects and flapping clothes or other things really don't mix!

I have a basic workshop safety-rule: I keep my face/head out of the line-of-flight of spinning objects as much as possible. When working with the lathe, I am always with my body slightly to the right from a spinning chuck.

 

They also sell round polycarbonate shields for lathes, but they are not very convenient for precision work on small parts.

I find it much easier to wear a face shield than trying to work around the mounted polycarbonate shield.

I use neither, only safety goggles (with or without built-in magnification), but then I rarely use the chucks for model work, only for my tool-making. For really fine work, where you have to look at the work from different angles, face shields are impractical.

I don't think it is necessary to soak everything in machine oil, so that when the chuck spins in the lathe, droplets of oil sprinkle everywhere!

Just light oiling will suffice.

Never had that problem.
