When using the lathe today, to make a little adaptor for SWMBO, The lathe started to make the darndest noise. It sounded as if it were coming from the gear head. My first reaction was that I wasn't putting any load on it how did I strip a gear??

Finally traced the noise to the motor drive pulley, the pulley is keyed to the shaft and the key had run out and was striking the fiberglass cover. The key just sliped right back in but there is no set screw to hold the key in place. There is a set screw on the pulley but 180* from the key. Kinda a poor design but an easy fix after I recover from the heart attack that it caused.
