Didn't know you could resurface a grinding wheel. How long does this fix last for? How does it compare to a new wheel?

I keep threatening to turn a 3x8 SC expando belt inside out and coat it with epoxy and dismonds. Anybody try this?

orrum, I've never turned one inside out, but I've re-coated worn 600 grit SiC belts with diamond. I figured the worn 600 was about as effective as a 1200, so I've put 300, 600, & 1200 diamond on them. Lynn

I don't know exactly how long my personal re-coat will last but I have used it on several stones and it is holding up nicely. I don't think anyone else here has re coated this low of a grit before, so the whole process is under development, so to speak. Compared to the new wheel, it kicks **s. The original new wheel was defective and came with probably only the tiniest bit of somewhere over 10,000 grit diamond powder. This was purchased as and was supposed to be a 60 grit wheel. Surprise, surprise!! It came from China Now the wheel actually does something.

Just an update on the longevity of the re grit. The pic below shows the condition after over a hundred cabs of varying hardness from lightning stone to agate. It's still cutting good and most of the diamonds are still embedded in the epoxy.
