I need ideas to repair my office chair while keeping the cost as chose to $0 as possible.
Here's what happened. I'm a heavy guy (~230) and use a fairly standard office chair.
The one point where the airshock inserts into the base of the chair is subjected to quite a large amount of stress, and for some reason chair manufacturers like to form this part out of simple pressed steel. It's somewhat inevitable that it will give under stress. Now the chair still holds up because there is an additional brace inside but it wobbles quite freely from side to side. Here's a paint diagram:
The little red wedge is a crack which has allowed the cylinder to become loose.
The mechanism is very similar to this one:
Replacing the parts will presumably provide a temporary solution, although if I can order a mechanism with a superior (much stronger) design it would definitely be a consideration.
I need your help to conceive a way to repair this chair at minimal cost, if repairs exceed $50 I may as well start saving up to buy a new chair.
So far I've tried a generous layer of JB weld, I thought I had it but it broke after about 4 hours of use.
I'm thinking maybe some kind of industrial / plumbing clamp.
Solutions do not need to retain the chair's ability to swivel or adjust in height.
The shaft is 32mm in diameter at the point it inserts into the base.
