    The advantages of the improved resin for centerless wheels are several. The wheels generally are found to be smoother acting. They remove heavy stock or light stock with a quiet non-chattering non-glazing efficiency. This is due to the ability of the bond to elongate or give a little under pressure. Some resilience is a characteristic of
