    I have an old B&D bench grinder that my dad gave me. It doesn't work right and after taking it all apart, I have found that the start winding of the stator has burned up. Does anyone on here rewind motors for a living, and could give me some guidance on either doing it myself or having it done. If I could get it repaired for $75 or so, I'd do it as I like old tools. I cannot find any info on it from B&D and my emails have gone unanswered. Its a Black & Decker No. 787 7" H.D. Deluxe Bench Grinder, Type A. Any specs parts lists or diagrams would be appreciated.

    You might want to give that press motor some loving also.

    The winding is toast, there is a sopot that shorted out that burned through three or four adjacent coils, and I dont see any way of repairing it without wrecking the undamaged windings.

    As far as the press motor, if it's toast, I'm hoping it comes off as a unit, I have a few one and two horse motors laying around with different frame sizes, maybe one will fit, if not, I'll get one that will. As long as the drive train is in somewhat decent shape, I shouldn't have any major problems.
