Black and Decker Valve Resurfacer Repair

That's a really nice machine, I have one.
Decades ago I had trouble getting stones or pilots for mine.
I ended up getting Sioux pilots and stones, and drilled the stone arbors out to press a suitable valve guide into, and use Sioux stones/pilots, with BD arbors/drill motor? and the rest.
Just if you get stuck, I didn't have ebay back then, lol
PS check your hi school auto shop for used stones .
