Are there any bench grinder wheel balancing experts here ? I bought a bench grinder but had to return it as it was impossible to balance the wheels. Thought I would spend a bit more and bought a better one, same problem. It was replaced and I spent a few hours trying to balance the wheels but still no success. I have tried two methods of balancing and scoured YouTube for tips but still no luck. I consider myself to be very practical and have built and fixed all sorts of things over the years but this has got me stumped. If anyone can suggest any tips or methods to stop me from scratching my head it would be greatly appreciated.
