thumb protection when re-pinning

[Piannaman@aol.com]

Dave,

I find a flat, smooth hard surface, such as the side of my pinning tool.  I 
lay it on the keybed(or something else flat and close by) and gently push the 
pin up into the birdseye.  Feeling the amount of pressure you have to apply to 
the piece to get the pin through(or not) can tell you how good the fit is.   I 
always push directly over the pin to avoid any kind of unsupported stress on 
the part.  I occasionally get a pin jabbing in the end of my thumb, but not 
often.

I also use the Mannino broaches.  They are one of the best tools I've 
purchased based on money spent vs. money earned.  The ends are REALLY sharp.  DAMHIK.
