It cost about $20 and came with a few different chisels. I then cut a tuning pin punch in half, did the same with one of the air chisel tools and had a welder join the front of the punch with the back of the chisel tool. I only had a chance to string a few pianos with this rig before the compressor and I parted company but I can attest to its speed (and noise). I prewound a whole section of tuning pins, giving each a quick tap to start each into respective holes, and after a suitable forest was built, I started driving in pins close to ultimate height with the modified air chisel. It took approximately 1 second per pin and, with adequate ear protection, was not at all fatiguing. Hope you're not doing this in a mobile home park. Thomas A. Cole RPT Santa Cruz, CA
