I have a 'Pistonola' of my own design. When I bought my piano it was not a player, so to do something different (I had heard of the Pistonola) I made my own, using two racks, each one offset . The pistons are 1-1/2" diameter brass and have "O" rings for the seals. The pistons are Delrin. 20" water gage suction gives approximately 3.2 pounds force. I am thinking of featuring this in the AMICA magazine if they so desire, plus my perforator. Steve Bentley
