This is my Kinyon style home made air hammer. The plans can be bought on the ABANA web site
for about $15. I built this with the assistance of my sons Noah & Andy. It took about a week to build (after having collected all of the parts & pieces).
We have roughly $1,000 invested in the material including about $500 for the Parker brand air components and the
steel for the frame. This does not include numerous plumbing fittings, hose, or
piping for a large volume of air from the compressor to the hammer. The 1-1/2" base plate is mounted to a pad of 4" x 6" wooden beams that are bolted together. The pad is then bolted to the concrete floor. The hammer is supplied with air from a 1-1/2" PVC line @ 100 lb. of air pressure. We have 3 compressors totaling 40 cfm. that can all be put on line at one time should it become necessary when I build the BIG hammer. The system has 230 gallons of storage plus the volume of nearly 100 feet of 1-1/2" pipe.
This hammer uses a 4" x 4" x 10" square ram with a 4" x 4" flat die. I figure that the hammer head weighs about 65 lb. More
