Depth Drill

 

In keeping with my tradition of spending more time making thing for making things than actually making things, today I made a hand-held depth drill, using a 12mm twist bit I had lying about, some oak, and a bit of copper tube for the ferrule.

These things are used to bore a hole to a given depth for lathe work. This both makes it easier to hollow out the form with gouges, and also gives a visual indication when you've reached the chosen depth for the bowl or whatever.

This particular one will go to a depth of about 105mm, which will probably be fine for most of the work I ever do on the lathe.
