Like a gas strut but can't leak and always adjustable both ways if you cock up. Compact as well.

I think I need more force than 9.55kg which looks like the biggest one they do, not weighed it but took some lifting when fitting back on the machine and I nearly broke into a sweat so it must be at least 20-25kg.

Thats why I thought gas spring, the ones I am thinking of usually go up to 40kg with a little valve in the end to release the pressure. If you are dead against this idea then fair enough I will come up with something else, got any more idea's?? !
