I’ve had a four jaw chuck for my lathe since I’ve had the lathe, but have never used it. I kept it in a protective plastic bag, but still wood shavings found their way in, and the protective oil polymerized, making the surface of the chuck a sticky mess. So it was time to disassemble and clean it! (And see how it works.)

I removed the jaws and gave everything a good rub down with liquid wrench and a rag. I needed to let some of the jaws soak, then give them a right whack to loosen the bolt so they could rotate. Once all the old lubricant was removed, I reassembled it.

The chuck itself does not have a maker’s mark and the instruction manual is not with my other manuals. So I had to look up some videos on how to use it (and found some really poorly translated instructions). I tried setting it up as pictured, but wasn’t comfortable with the security of the grip, so flipped all the jaws around to hold smaller stock, which does work well.
