Working on a green Bradford Pear blank. Sawed it round. Attached a
faceplate and turned the outside and dovetail socket. Then it
happened. The faceplate was attached with six #10 screws. Three came
out ok (I use an impact driver). The fourth one twisted off at the
neck. The fifth and sixth ones could not be backed out. Ruined an
impact Phillips bit. Finally drilled out the screw heads and cut them
off with a cold chisel. Threw that blank away. I think I will start
waxing the screws.


HI GW,

I use no. 14 spax screws from McFeely's. I don't pre-drill, and I use a
no.3 square drive bit.

AKA Robertson screws. A Canadian invention.

I've turned over 200 bowls from 6 - 17 inches,
and never had a problem. I use a 12 volt cordless drill to drive and
remove them. I reuse them until the square drive won't drive them
anymore.
