Wayne,
Thanks for the idea. I already have a 2-9/16 self-feeding bit such
as plumbers use to cut holes in framing for gas and water lines.
Already have the Hole-Hawg drill to power it too. Just need an
extension since these bits don't have a very long shank to them.
Now if that big drill doesn't slap me silly the first time the bit
hangs up, have that hole drilled in no time at all.
