<BODY lang=EN-US vLink=purple link=blue bgColor=white>
<DIV><FONT face=Arial size=2>I recommend that you experiment with your palm
nailer on a practice piece of pinblock using various air pressures. I have
found that with mine (a Danair) it seems as though the air pressure affects the
rate of strikes the hammer makes more than the force of each strike. And for
whatever reason, it seems that at maximum air pressure I have good control, but
it does hammer away faster than I like. As the air pressure decreases, I gain
control, yet the strikes are rapid enough the operation is still smooth. For my
setup, when the air pressure drops lower than 40 or 50 psi, the strike rate
slows so much that it feels erratic and that I don't have the control that I had
at higher pressures. At the lower pressures I can make the nailer give me
individual strikes, but each strike blows that pin in a lot - like maybe
1/4-inch. At the faster strike rates associated with higher air pressures, I can
make a burst of strikes that maybe only drive the pin 1/8-inch.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The bottom line here is simply that I recommend
experimenting with various air pressures to see where you get an acceptable feed
rate and maximum control.</FONT></DIV>

good tip, I think the recommended pressure is 90 psi which probably

palm nailer on my occasional restringing job. Tip is unmodified, and the
key is to set the compressor pressure fairly low, say 30-50 psi, and STOP
before driving the pins too far. DAMHIK. Also,
important to lever the pins back against the string tension when starting the
nailer, and align the pin with the hole axis, so as to not dig out the top of
the hole in the pinblock. </SPAN></FONT><o:p></o:p></P></DIV>
