That's a mouthful!

I have a collet-holding Levin tailstock lathe, but was curious if I could make a device that allows me to mount a drill bit on a conventional tailstock runner.

Took me a long time to get the taper right.  Turns out that the taper angle is 2 degrees.  I was able to do this accurately with my cross slide.  The drill bit post is pretty common.  You can buy assortments of all different drill sizes with the same post (base).

The bit shown was broken, so it was used to test the setup.

I used brass because it was easier to turn...and quicker.
