I noticed in one of the videos, Andre recommends lock-tight to fix a loose axle, and that it was glue-like. I was wondering, will lock-tight glue the axle in place so that you can’t screw/unscrew it, or will it be loose enough that you CAN screw/unscrew it?
Thanks.
It depend on the type of loctite you buy. The red is the one you CANNOT unscrew once you put it on. And the Blue is the one that you can unscrew if you need to.
oh, okay. That clears up a lot of stuff. Thank you!
and also thank you for excusing my many mispellings 
Well, Loctite is the most common brand of what you are looking for which is thread locker. But people usually call it Loctite.
