Back to removing the cylinder. The story of my St. Louis Pump. I laid it down, the cylinder on a couple of thick blankets. Took a tool that looks like a dentist pick and started picking away at the caulk. Remembering what someone had told me, never check the cylinder to see if it loose, let the cylinder tell you it is loose. Picked at it all day, could see the cylinder was getting loose, then all of a sudden a loud crack and it was in pieces. So, what does this mean? Even if you are very careful it may still crack, keep in mind it has been under a lot of stress for almost 100 years.
