The lathe is a Grizzly GO800, which is a Harvey Tool lathe, basically the same as a Laguna.
User error - started up a 12" a 2" bowl blank while the spindle lock pin was still in. I have done this before while turning light objects and there was not a problem. This time the momentum ground the spindle lock pin into the spindle pulley and bent the spindle lock pin.
This is not carried by Grizzly. I welcome other suggestions to replace the part.
