Bet you haven't seen this thread in a while haha
So I'm setting up a tech deck handboard, and 3 of the wheels went on fine, but there is one axle that the bolt can't go on. Maybe it's stripped. I tried super glue, but I can't move the bolt onto the axle at all, except right on top. And since the force is so great when I land, the bolt only stays on for a little.
Any advice? Maybe the answer is just more superglue, but I don't want to destroy the axle or anything.

it's definitely stripped, happened to me many many times, your best bet is gorilla glue or some really strong thick adhesive

If you go to your local hard ware store you should be able to find a "Tackle and Die" set. They have tools to rethread stuff. I'm not sure if they have one small enough for a handboard, so you'll have to ask.
