Air Hammer

[Tom Servinsky]

Terry,
The big difference is if you install your string prior to driving the pins
or after.  The head that comes with the nailer is fine if you are driving
the pins first than installing the pins. Otherwise, according to Danair, the
head will break off the string at the coil.  I haven't used mine yet so I'm
not talking from experience...just the advise from Danair ( the horse's
mouth).  Apparently the adapted head has a much shallower recess. The
diameter of the head also fits the tuning pin head better, avoiding any side
movement.  Again, not talking from experience. Just passing along the word
from the top.
Tom Servinsky, RPT
