    Default CNC down need new stepper motor

    I am having an issue with a stepper motor on machine that I bought used 6 years ago. The company that makes it is out of business and I need to find a replacement. Most new NEMA 34 motors are using a 1/2" shaft and this one has a 3/8" shaft. I do not mind a bigger motor as I have plenty of space and have updated Gecko drivers but need to work with the pulleys and belt size I have. Here is the info I have.


    Current Motor
    MCG IH34110
    Does not need shaft on both sides as only one is used.


    Pully
    3/8" ID with 7/8" OD .080 pitch




    Any recommendations on motors and or pulley combinations would be great.

    Left-field idea:

    1. Bug cheap NEMA34
    2. Find someone with a cylindrical grinder (or a toolpost grinder on a lathe), and grind shaft down?

    Room for an adapter 1/2 bore one end, 3/8 shaft at the other?
    Much easier to go the other way...

    Bore out pulley. Not hard, and pulleys are cheap.
    Mounting the pulley so it is centred is key. Use existing hole as a guide.

    Cheers
