Palm Nailer

To keep from driving them too deep, I always just stop driving 
just short of going too deep. Always.


When I don't, I get out my modified screw jack (sort of an 
un-screw jack). To use it, I block up as necessary underneath 
with wood scrap, and turn the top end up into the pin hole 
until it contacts the bottom of the pin, then another 1/4 turn 
to add pressure. On top, turn the pin slightly CCW, then back 
CW to where it was with your tuning lever, and it will ooze up 
out of the block a bit like magic. Repeat the jacking and 
oozing until satisfied with the pin height, then stop. Put the 
jack away where you can find it the next time this never 
happens, pretend it never happened this time, and get back to 
work. This can be done either with or without string tension.

Enjoy,
Ron N
