I think this falls under the DIY category, as I’m essentially trying to find a way to renew the bond between a set of urethane fingerboard wheels and their single-bearings.
Backstory: I purchased a set of wheels online and the single-bearings were not performing well right out of the bag. Further inspection showed that the bearings weren’t spinning at all, where I think the bond used to keep the bearings in place may have leaked into the casings and caused them to freeze up. The company did replace them and the new ones are so much better. They wouldn’t accept the old wheels back and my brain won’t let me throw them away (yet). I doubt I could sell them as they are (unless anyone wants them ), so I figured I’d try to fix them up and maybe use them on an outdoor setup.
Preparation: I first popped the bearings out of each wheel, which unfortunately ruined the cores’ original integrity because I watched the adhesive strip out as the bearings came loose. Then I heated each of the bearings with a lighter until the adhesive ignited. This combustion cleared the bearings of any foreign material and now they all spin freely! However, the issue that remains is fixing them back into the wheels. There are no internal grooves and the cores are not funneled, so the bearings slip in/out without any friction.
TLDR: With all of that said, here’s where I need the DIY advice - does anyone know a safe, reliable way to keep slipped single-bearings in place? Otherwise, I’m just going to toss a line out on eBay to see if anyone wants my old wheels for a few bucks. If not, I’ll probably have to throw them in the trash. If anyone has any good answers, maybe this will help others who have similar issues with slippery-bearing wheels in their arsenal.
