Palm Nailer

[Bill Costanzo]

OK, that makes sense. I imagine each tool will have it’s own unique psi
sweet spot.

BTW, sorry for the multiple posts, the originals were sent first thing
yesterday, and hadn’t shown up til this morning.

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.

 

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.

Thanks, Dave,  good tip,  I think the recommended pressure is 90 psi which
probably would have blown those pins right through the block.

Bill, I am certainly not an authority on this or any subject, but here is my
experience.

 

I also use the Harbour Freight 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.  

 

I am sure you will get better info from others who are more than occasional
restringers, but this has worked well for me.
