No problem, looking into these things is all part of the fun. I hope they can find a convenient solution for you. The guys at the rewind place might be amused to read this thread too!

On the bench here in the workshop I'd have done the swap-around of the winding ends and run it up on a 3-phase variac with a lamp limiter, which would soon prove whether the mod was correct and prevent damage if one winding was out of phase etc. But I appreciate that from where you are, especially with no 3-phase to test with, it's a bit of a challenge and a leap of faith.

Earth it the same as you would any other metal cased appliance - just make sure the earth connection in the mains lead and plug is sound. At the equipment end, make sure each item with mains connection has it's case earthed.
thank you!

Thanks a million for your help here and on the other post, this project has opened my eyes and head up to what is doable and the need to ask questions, I really did want to learn a bit more about motors, this was great and amazing to see how complex it is and see whizz kids in action :) i studied some electronics theory years ago, it was never my strong point.

Hey, I costed all options to get the power feed working, it was not economical for me to proceed, I bought I knowing it was a risk but thanks to the forum I was able to see what was involved. I have to say I really enjoyed learning from you all. I am using the knowledge gained to make really smart El trical decisions going forward . For now I need to stick to 220 v and buy machinery at that. Thanks again!

Hi again, SUCCESS, I have purchased a (think 9hp) diesel generator for a good price, it is key start, it's a few years old and needs some tidying up and is a bit noisy but is for a rural workshop. It has two 110 and two 220 sockets and has another socket pictured below, is some one able to help identify what output the other socket it is and if I need to test it to check what's coming out. It may be an old connecting pin ( I'm not sure) in my workshop, I need to use some motors ( including a custom power feed, I want to know what size and phase will work with this. It would be great to hear some opinions. Thanks all! Hope everyone is keeping safe .
