    Hi all,

    The feed motor on my newly acquired Bridgeport is poorly, it lets the magic smoke out when I run it. It's had new brushes, cleaned up inside, commutator skimmed, resistance checked and commutator leads restaked to decrease areas with high resistance.

    So I reckon it needs a rewind. I've contacted a couple of firms with no response...I take it for a little 90v DC motor it's not worth their hassle, a new motor is hilariously expensive at £577 ex vat, be cheaper getting a pair of new power feed units and adding one to the saddle. Also considering getting a 48v DC electric bike motor and running it from the internal transformer.

    Anything else I can check or possibly rectify at home?...turning into a bit of a money pit this bridgie.

    My cousin has a motor rewind business, typically charges between 20 to 50 quid to rewind motors.

    ............. he's based in India

    With shipping it would probably still be cheaper. :D

    Probably, but with our courier service it might come back more broken

    yep, ive said before, my mate runs a DPD franchise. They have quite a few "lost" parcels. Sit in a corner of the unit for a year. If they are not claimed by anyone they are auctioned off to the staff (all blind with boxes unopened). Some right good bargains have been had

    The feed units come up on Ebay from time to time.
    Or replace it with a new Chinese one.
    Just do a search on Ebay for Bridgeport power feed or similar.

    The drive boards are prone to going pop so there must be used spares about, wasn't there someone here struggling with a dead one last year?

    The drive boards are cheap to replace/repair though,about £100 on a return basis

    It will likely come to that...alongside a Chinese DRO. :laughing:
