Hinge pin removal ?

[B. Dudley]

do not heat the action. There should be no need to do this.

With all the actions I have stripped for parts and roll joints removed, I have never had to use heat and usually never even oil.

The screw is just in there tight. Nearly every one I remove has the threads librally coated with machine oil left from the day it was new.

The action in a drill press might be needed, but usually the bit in a socket handle for leverage will release the really tight ones.
