    coupling a worm to the stepper motor

    The problem is that the worm and the stepper motor have different radius, is there any hack/simple solution?

    Thanks in advance, I'm totally blocked because of this issue, the rest is all easy :-)

    bore one side of the coupler larger or use jaw type couplers which can mix and match the proper diameters.

    I googled it and it sounds like the perfect solution, there are not many on ebay unfortunately..

    What is your preferred shop for buying them?
    Thanks!
