Air Hammer

I hate to see you folks getting tips machined for possibly no good reason. I
wind my coil on the pin before driving it into the block. I had no problem
whatsoever. Let me go out in my shop tomorrow and measure exactly how the
stock Danair Palm Nailer tip fits atop a tuning pin. I will report back to
the list. I guess I don't remember the exact relationship between the tip
and the coil, but I think you are OK, with room to spare! I'll let you'all
know!

In all honesty, I would hate to trim my tip any shallower, because then
there would be a greater tendency for the hammer to hop off the tuning pin
top when hammering those last few whacks real slow. When you do those last
few whacks, you will want to do them slowly, and the hammer really bounces
up because you are just pressing down enough to get one or two whacks out of
it - a shallower tip would increase the likelihood of the nailer jumping off
the pin. (Let me tell you - you definitely do not want the nailer jumping
off the pin top in a wild uncontrolled manner - I speak from experience -
now where is that touch-up brush!)
