Just messing around...
I have two different size pen mill heads..
one takes 3/16" shank, the other 1/4" shank.
So, the idea (read boredom) was to make a pilot with one head,
and two shanks. They are interchangeable. The brass bushing mates the smaller shank into a counterbore in the end of the pilot. The threads are
tapped way deep into the pilot, below the counterbore.
Pretty sure I have not seen this crazy idea before.:biggrin:
Thanks for checking it out!
