I have not tryet hack saw blade before. Done the pick tools before but thought there was something faster and safer? Again thanks for the help.
When you are dealing with 100 year old glass....slow is the only way. Extreem care must be used otherwise the end result is always bad....bad....bad. Always remove the cylinder while the pump is standing upright. The stress level is [down] on the glass as it has been from the first time of assembly. NEVER try to remove the glass while the pump is on it's side.....the glass is weakest and more apt to break in that position. paul
