Air Hammer

[Greg Newell]

Tom,
    Check online. I'm sure you'll find a decent price if you search a bit. I
think Del recommended the Danair but it's not the only brand around. I'm sure
you'll love using it for this. Stringing beats the body up enough all by itself.
This will take away some of the discomfort.
