Hi folks,
I acquired this old beast a week ago -

.
As you can see from the photo, it's an inverted horizontally oriented wall mounted Eagle surface grinder, a little known model. Either that or I held my camera sideways, I don't remember

Can't wait to get it operational, alas, it has a three phase motor on it. Motor weighs a ton and is mounted on a steel plate that's probably 3/4inch thick.
I have a VFD to run the motor, but the problem is it's undoubtedly wired for "high voltage" or in star configuration.
I gather from reading around that I should be able to rewire the inside of the motor into delta so that I can run it at 240v 3ph. I've done this on modern motors where you just move some jumpers, but I gather that on old ones you have to work a bit more.
I don't really know where to start here - do I need to start snipping some of the tie material that's holding all the wires together, to try to find the ending of each circuit? Should I just dive in with some careful snipping action? Am I even looking at the right end?!
Would appreciate any advice.
Cheers,
Rich
