Dual pilot

[johnnycnc]

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!

You're always coming up with something new(that"s a good thing). Would that be an "A" and a "B" mandrel ?

Hi Tom, long time since we talked. I sure enjoyed that visit we had!
A and B sounds about right.
I do like to try new things, keeps me out of trouble (usually).

Great idea! Nice! Can we look for this to appear on your web site?

Thanks everyone for the comments!

Hank, I wouldn't count on it, it was a fair bit of time.. probably not
cost effective.
But it was a challenge to figure out, which was what I was really after!

John, my alzheimers must have kicked in because I read pen mill but thought mandrel. I think I'm back in my right mind now(I don't know if that's a good thing or not).
Any time you're down this way, stop by, you're always welcome here.
