A guy I know that is cleaning out his storage areas spent like $40 getting this 8" Vintage Black an Decker grider back to health and it still hums but won't start on its oown. It may just need a capacitor, but I still marvel at how bullet proof these old grinders were. The tool rests are every bit as thick as the old C-man Block Grinders and the Baldors. I can't glean much info off that ID plate just yet, but will try as time allows. Also pcked up an old 1/4" Zephyr drill that has what appears to be a keyless chuck, but it's frozen up and likely not going to be salvagable.
