>Nope, no reason at all.
yeah, 1/2" is harder!

Odds are if you start at 1/2", you'll finish at 1" or greater until you've mastered the tool. One catch redesign.

>Ken, the only important thing is that you drill a hole. The hole is an aid in hollowing and serves as a depth gauge. When you get to the bottom of the hole when turning....stop! I use a hand held 3/8-inch drill myself.

>Thanks. What does the (sp)stand for?
A friend suggested an electricians self feeding bit with the screw ground away. Any thoughts?

>Thanks Much:
I think I'll give that a try. I started a hollowform this morning and about ready to drill the hole.
