    Default Lathe motor, took a ....

    so I'm working on my lathe this evening turning a brush out of American Chestnut. Flip the power switch off, to evaluate and went to turn the lathe back on to continue sanding. Nothing! Just a low hum.....
    Now my Lathe is a Craftsmen 1950's that I believe was fitted with bearing's vs. brass and oil cups originally. I have another one probably 5-10 yrs. older that's setup this way.
    The motor will spin with the belt removed and a little motivation. but no luck under a load.
    So I started pricing motors, need a 1/2 hp 1750 rpm with I believe a 5/8 shaft (didn't measure it). Prices are steep on these motors, I could buy a basic Jet lathe new for what they want for a motor. Any sources that someone can point me to, rebuilt maybe?
    I did find another lathe same model, with tooling that I don't have, a bench meant for the lathe and guess what it has a motor attached....all for an 1-1/2 hr drive and $95.......worth it? I don't know, that would put me up to 3 vintage lathes of the same make and model, spare parts? these thing's are built like tanks.....

    well worth it,my motor burned out 3 weeks ago,non stop service since 1935,they wanted 300 bux to rewind the armature.
    Went to the bay,found a brand new motor with the southbend reversing switch,all wired and the proper mounting bracket $150 shipped.

    As a side note,on the non arbor side of the motor,is a side plate,unplug the lathe,remove the side plate (two screws) is about 4 wires connected on a micarta mount,remove and wire brush them,re-connect, it may work,has in the past for me.

    ended up purchasing a Leeson 1/3 hp 1725 rpm motor - there went my razor fund.........been saving for a Hart
    thanks Bill didn't see this until after I made the purchase........I will try the wire brush. I think I will build a box, shroud or something for this one, I'm sure the dust created while turning doesn't help!

    wood dust is always an issue,shroud of sorts is a great idea,my grandfather bought the lathe new in 1935,160 bux.
    That old westinghouse motor lived along life.
    Nice to have a new cap start motor with sealed bearings (marathon 1/2 hp with sealed bearings, no more oil cups

    I downloaded a PDF file I found online for my Lathe - it ended up calling for a 1/3 or 1/2 hp 1750 rpm motor.
    Here's a pic of my setup with the new motor. Bill that thing is a beast! metal lathe?

    as a side note, the first lathe I had is exactly the same (kept for spare parts) and it had oil cups, the motor that came with the current lathe in use had oil cups but it never seen spin time since I've owned it. Oil cups are cool, just adds to the Nostalgia
