Ken K from calvert sent me a Waterman cylinder to sleeve. Shaking the cylinder it was obvious there was a lot of rust scale inside the jacket. Ken wanted the jacket removed and cleaned. Tapping on the retaining ring didn't start to move it, heating made no difference. I used my Dremel with a cutoff wheel to slice into it, a little over 3/4 of the way through it popped. The jacket was still stuck tight, heating again made no difference. I didn't want to damage it by tapping on it. I decided to try water pressure. I threaded a 1" shaft to fit in the top of the cylinder in place of the sparkplug bushing, screwed it in and slipped a piece of 1" hose over and clamped it. This provide a seal and room for the cylinder to rise. A plate over the water pump mount was tapped for a hose barb. I connected it to the water hose and opened it. A few little leaks but the hose had good pressure. It took a few taps in the ring area with a bar ground to fit the contour of the cylinder, it popped off. The retainer ring was placed in a vice with the break area matched and acetylene welded. I then put the ring in the lathe with the weld over one of the jaws, turned it close and filed to finish. The machined area was obvious so I heated ituntil blue and dipped it in used motor oil, had to tell where it was repaired. If it didn't move my next try would have been the grease gun.

I swear JB, you are a GENIUS. Is there anything you can't do?
