I picked up a used square barrel cylinder the is 77.45 bore. Would a 77.25 piston work? I tried a77.35 and it fit but seemed way too tight. Thanks Steve...
If you are to obtain a reasonable service life and reliable operation I've found that an accurate measurement of any used cylinder for taper/wear in the port...

Rick - Just a point of interest - are the shoes grooved? Who did you get them from? Are they riveted? Are the rivets solid or hollow? Could the rivet heads...

where can the walnut shell media be found ? any changes need to be made to the blast gun ( nozzle ). i have heard of walnut shell being used before but i have...
