but it is hard to find reasonable priced wooden office chairs. I live in an old ranch house and use an old wooden kitchen table as a desk. a modern office chair looks so out of place. It is a cheap POS but I would like it to last for at least a year! I have already had to repair the shock absorber (with a PVC shim and baling wire, had to get a new right hand arm (under warranty) because it split out right away.
as to this current repair I like your advice and got some gorilla glue but here is the thing. those little inserts didn't pull out - they somehow come unscrewed out of their holes. when I dismantle the piece I have to physically screw them back into their holes, they don't just push in and out. the damage to the openings of the holes isn't from the inserts pulling out, it is from my using a pair of needle nose pliers to screw them back in. There must be some kind of official tool with reverse threads or something but I don't have one so I was just grabbing the insert by the very edge and trying not to ruin the internal threads for the bolts.
I don't quite understand the actual physics of them coming unscrewed ( ) because I can tighten the bolts down pretty good at first, then they loosen with use and trying to retighten them is when the inserts really seem to back out of the holes.
so I figured some kind of glue would be my next attack before maybe trying the next size up inserts and bolts as suggested above.
I have never used gorilla glue so this will be a first. the fact that it expands sound like it should get it to help hold better, especially if it sticks well to the metal.
thanks for the tip on using a bit of tape (duh, I would know that for plumbing why not here?)
