Thank you so much, those shaft collars look to be a much better design than the thing I drew (not much of a surprise to be honest!), I can stack a series of these instead of looking for one big solid one.
I didn't know that the cylinders were so dangerous 😬 I must have lucked out; I've had to use extreme brute-force methods to dislodge the old ones when it was time to replace them, pointing the thing directly at my guts and face while I work it loose with a hammer and spanner. Sounds like I was unwittingly playing Russian roulette with my chair. The difficulty I have in pulling out the cylinder is why I wanna just go with a "static" setup, it's way too much work and effort for something so simple. Now I can also add "don't want my cheekbones to get lodged in the ceiling" to the list of reasons to go static.
Thanks for the info and the warning!
No problem, I'm just glad all that time I spent memorizing the McMaster-Carr catalog finally came in handy!
The cylinders are sealed units, so they're safe to handle even after beating the crap out of them. The danger happens when people decide to repair a failing seal or leak and try to open the cylinder itself to get at the piston head - usually with a hacksaw....
