Knuckle preserver

[Skierdude]

I got tired of mashing my knuckles on the lathe when using the chuck key. The one that came with my lathe is too short to use unless the socket in the chuck is near the 12 o‘clock position.
So today’s project was a new longer chuck key turned and milled from a piece of 20mm 4140 HT.
After browsing the web I don’t think I need to heat treat this any further, it should be fine as is.

Very nice. Have been saying I was going to build one like it for a long time.

Knuckles? Preserved? Is that what you use to make a knuckle sandwich?

I read the title and seriously thought it was an allusion to brass knuckles lol. I really need to do something like this for myself. Is the handle glued in or is there a set screw in the end?

Have you given thought for next wet Sunday when you can make two for your 4-jaw?

Haha. I think I’m a bit past the need for brass knuckles.
I used a 6mm setscrew to secure the handle.

It does look like a bit of a wet Sunday, I think I’ll start on a slitting saw arbor. I might even have a go at turning a 3MT taper !
