Re: What Were They Thinking to Remove Cylinder
If I thought I could present a thesis on the subject, it
would be my defence of the Cox cylinder wrench.
I've removed several(tons)of cylinders with the wrench
in the ports, using enough properly applied heat. Currently
I'm using a brulee torch. Stole it from my wife. She never
makes creme brulee for me. I don't even know what it is.
If you apply enough heat to the crankcase and don't get the
cylinder too hot, the force on the wrench will be minimal.
Keep the heat away from the base of the cylinder, and don't go
crazy. You should have a vague idea of how much torque it'll
take to damage the cylinder. Don't be tempted to muscle it. If
it doesn't come free, more heat! If that doesn't work, walk away.
Over night is best to mull it over, then re-visit.
If you have any, practice on some beater engines that are totally
clapped out. Proper heat and a deft hand will do it.

Re: What Were They Thinking to Remove Cylinder
Correct-amundo Bob! Heat is the key. I use the heated ultrasonic bath though. Proper temperature is ”ow-ow-OW”, but no cusswords, nor blisters.
I like the style of both of the cylinder wrenches, but I would like them to be thicker and tougher material. Like twice as thick as the originals.
For the glowhead it would be nice to have a tool like the old style, with the ”closed loop” instead of the open style that always seems to flex and/or slip, or get in between the fins
Free tip to Bernie and Matt: How about making some quality tools to replace our old Cox wrenches? Twice as thick, proper steel instead of the bubblegum stuff used in later wrenches. Also make them separate, instead of the all-in-one style so that they don’t dig their sharp edges into my palms in the rare occasion I have to use force.

Now that is funny right there. Glad to see that I am not the only one. I was wondering if for some strange reason I was using them improperly!
