My home built power hammer, constructed from Ron Maurin's toggle arm assembly main post is a 4x4x1.25 inch post, the pulley wheel I found a 24 inch squirrel cage blower had a 15 inch pulley on one end and a 1 inch solid shaft, I got
the saddle bearings from a local hardware store I used a 1 inch thick plate metal for counter
balance for more precise measurement contact Ron's site. This hammer serves it purpose for me enjoy the pictures.
