Air Hammer

[Tom Servinsky]

Terry,
I found with my 3.5 hp 30 gal. compressor...not big by most standards, I was
able to  work between 50-60lbs with good control.  What I like the best was
I could back and touch up my depth with a quick "pop"  from the palm nailer
and would accurately move the pin 1 mm.
The think the relative question is how much torque are you shooting for in
your tuning pin fit.  Obviously higher torque will require high  pressure
from the compressor.  With the Florida pianos and the probability the pianos
are going to stay in Florida, we aim for 120lbs, which after  several
tunings provides for a nice tuning feel. Not too much work and yet ample
enough torque to keep the pins stable. In those situations I found 50-60lbs
was ample pressure.
My next string job  will be for an out of state  client with extremely dry
winters.  We will be aiming for a much higher torque and thus the pressure
will increase as well.
The Palm Nailer, in  my opinion, is impacting the rebuilding industry as the
the Accutuner did for tuners when it first came out.  An incredible tool.
As for my earlier comments about the need for the special tip...hog wash!
This tool N16-16 works incredibly well right out of the box and personally,
at this point, won't change a thing.
