Hopefully this isn't reviving a dead thread, but you should be able to fit two wrenches on the drawbar. I believe I see it in the photo your posted. There should be two flats on the spindle shaft near the square head of the drawbar. It will be pretty obvious once you see it Are you able to just give the wrench a few good taps with your wrist while holding the spindle?

Is there any more information about the Weiss issue? I have a PM30MV-L that is a Weiss machine. It's been fine so far - just a few cosmetic concerns since it's a "hobby" machine.

How is the new brushless motor?
