Okay... so I think I have a small solution... don't know if it'll work, but it's worth a try.

So, the wheels my mother got me might not be as bad as I thought it would be, considering the M10 nylock nuts I have, I can try and get them into the wheel. My only question is... would Epoxy resin be a good kind of sealant to keep the bolt in place and have a decent wheel, or would it be way too brittle for the task at hand?
