Palm Nailer

[Farrell]

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.
