While I cannot see that it would do anything but lock itself and burn up the spindle drive belts on my Sheldon if it was turned on in that locked condition. With the OEM 3/4 horse, or this VFD driven 1 horse. But, it does seem to have a reputation for broken backgears. I would much rather believe the chuck got stuck, and the desperate operator engaged both pin and backgear to lock it, then put a 2 foot crescent wrench on a jaw to unscrew it. That I can believe would overstress the teeth, if not outright break them. But who can say for sure when that may have occurred in the history of a 50+ year old machine that just followed you home? > While it is no longer produced, Grizzly still has the manual available > for the model G9249 lathe.
