Broken Screw Extraction

[Joe And Penny Goss]

Hi Terry,
I found some hex drive bits that have a u for a tip I grind them to a sharp
point and can back out a screw ( real hard ) with them even with the
pressure bar on. I think part of the process is the pounding on the screw
that loosens it in the wood, I have never had to try removing a screw that I
have put in. When replacing the screw ( if you get it out easy ) consider CA
to make the screw hold without plugging and drilling. Some thin will stiffen
up the fibers quite nicely.

> Anyone have any good suggestions on how to remove a broken screw from a
pinblock? One of the pressure bar screws on the upright I am restringing
twisted off. The break is slightly above the pinblock surface, but well
below the plate (about a half-inch hole in the plate). I think it is about a
#10 screw.
