    I'll try to post a picture in the next day or so.

    I'm wondering if this motor would be reasonable if I choose the replace motor and use a jackshaft method?

    Unimat SL

    Hi
    My Unimat SL would pop the breaker and when I tested it with an ohmmeter
    it showed a ground. I inspected it and could see nothing. To make a long story short I cut about 3" off the cord and refastened it to the motor and its been fine ever since.

    J S , 48 volt D.C.. Maybe start looking at military surplus. Ships wiper motor? Had a 44’ foot coast guard but still 24v. Pretty sure Mil use higher DC. Any chance Mike you can send a picture?
    Cheers, Bob

    SJH, I’m thinking he’s used it for his bike with many mods. Not too often you need to see a lathe screaming down the road at a buck 50!!

    Another possibility would be to take the bad motor to a motor shop and see if they can rebuild it. It may be expensive compared to a new motor of similar size but this may be cheaper and easier than locating a replacement and possibly modifying it.

    This is what I know about the motor:
    Here's what I know about this motor:
    80 Watt/ Max Power at 50 W
    Reversible
    48 volt DC
    Power is supplied by a power control built into the body of the
    lathe
    Motor goes into the frame of the lathe.
    Lathe motor is weird shape. It is a plan cylinder with the
    following dimensions:
    5.374 inches ( 136.5 mm) From tip of shaft to endbell
    .639 inch ( 16.24 mm) shaft
    .198 inch (5mm) shaft with machined flat
    4.78 inch (120 mm) motor casing
    1.913 inch (48.6 mm) motor casing diameter
    Electricl connections are at the end of the bell casing
    Motor is marked VDO Made in W Germany. The numbers 210864 is
    marked
    on the side in blue ink as well as 4190 in a square.


    THANKS!

    Do a search, I thought I had read where Evan put a different motor on his unimat.

    Have you checked for any Yahoo user groups iBorg? Read somewhere that the motor on the earlier Unimat was a pain.

    i think a trip through the Grainger catalog might be a good place to start to get ideas on where one might find a motor that could be adapted and look original or close to it. They have an online catalog, however many of us prefer to turn the pages.

    What are the specs on the motor and it’s physical size? A picture would be great. Might give some us a few ideas to pass on. But you might be in the position were you need a lathe to fix your lathe, been there. Nothing weird about wanting something to look just so.
    Cheers, Bob

    Random idea: could you adapt a motor from a Sherline lathe?

    I tried Blue Ridge a while ago, they're about an hour drive. They basicly told me that they no longer carried parts for the lathe and could not direct me to a replacment. I guess I'm going to be building some form of adaptation. Now the challenge is to make it look neat enough that I'm not frustrated by a "cobbled" look.
    Weird, I'm as interested in looks as performance.

    Web search for "Unimat Parts" =

    http://www.unimatt.com/Resources.htm

    They list several sources. I would try Blue Ridge first as I have used them before and got satisfactory service.

    There were other hits if that one does not pan out.

    Unimat PC Motor

    I have a Unimat PC. Its a nice small lathe compared to other Unimats. It serves my purposes well. Unfortunately, I hurt the motor and need to get it replaced. It is a bit of an off design as the motor goes through the lathe casing. Anyone adapted a different motor to a Unimat PC and would be willing to share with me?
