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?? !

Just ran the spindle again and still not happy with it.....

The problem bearings at the moment are 2 x 16004's - dimensions OD 42mm x ID 30mm x width 8mm

Decided to change them for some 6004's - dimensions OD 42mm x ID 20mm x width 12mm

Will need to do a bit of a mod to the housing and make up a new spacer for the spindle but think its worth it as they have a higher load rating than the originals.

Just rang my bearing man up and he has them in stock, apparantly they are used quite a lot for motorbike wheel bearings and he has plenty on the shelf. Price - £3.50 each for NSK's!

Where's me van keys.........
