Failed Bushing Hackery

Danielle’s desk chair began wobbling, and disassembly of the base showed that a nylon bushing had come apart allowing the chair to wobble side to side. The image above shows my attempt to rebuild something like this bushing out of nylon cable ties, but this somewhat failed. The chair no longer wobbles when in the lowest possible position, but it has enough friction that turning is difficult and the hydraulic height adjustment doesn’t work. I suspect the friction of these little cable tie heads is too much for the lift assist.

It’s too bad the low position is a bit too low for Danielle to be comfortable sitting at her desk. Maybe if I’m lucky I can find a replacement bushing, although I don’t see a way to get it installed as the top of the tube for it is crimped to hold it in place. Maybe an entire chair base assembly would be needed.

Oh well, at least it doesn’t wobble any more is usable as a low chair.
