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.

Yup, interesting how they are getting harder to find. Lately my local
outlets have gone to Torex

I have some SS Robertson screws that I use on green wood. As they are
harder than regular screws, they last as the holes don't distort so easily.

I gave some to a carpenter in the UK who used them for "security" jobs
as it was highly unlikely that anyone would have the right driver to tamper.
There is also a house in the UK that was owned by my brother in law that
will be difficult to renovate:-)
