Project Lantern Chuck
#1
I got the parts printed for the prototype and mocked it up. It appears it should work fine.  Thumbsup

I didn't print threads on the screw end or on the nut. For test purposes I just made them a press fit since I had no plans on actually chucking it in the lathe and trying to cut a screw to length with it.

Pretend that the #8 screw is actually a piece of 3/16" drill rod. It's the depth stop for the bit holder. I thought I had a piece but no 3/16". The range of screws that I want this to be able to modify is #4 - 1/4" so I made collets for the smallest and largest sizes to test out.
Sorry for the blurry picture holding the #4 Phillips head screw in the chuck.
That set screw shown on the collar of the last picture will be a dog point set screw that will fit into a slot milled into the bit holder to keep the holder from rotating.

Pretty slick. This 3D printing is almost like cheating!  6799
