Am attempting to modify my bench grinder, replacing the thermal fuse with a
thermostat, but I can't get the damn thing open. Once I remove the four
screws that fix the "end-cap" (sorry, I don't know what the "caps" on the
sides of the grinder are called...) said end-cap spins freely, but refuses
to relinquish its hold on the armature (sp?) shaft. Any ideas as to how
this thing might be built, and how to gain access to its innerds? It's a
3/4 HP BG-6, put out by AJ Tools, if that helps any. Yer basic 6" (2-wheel)
bench grinder from 30 years ago. Draws 6 Amps and spins at approx 3400 RPM.
Any help is greatly appreciated.

Thanks,

Dave
