Hi Guys,

I will follow your suggestions as best i can!

I need to get started by figuring out the connections. The panel is marked up as three phase with 6 brass bolts for connection, which i why i thought it was a three phase motor in the first place (i guess it's a standard fitting rather than one made for each type of mill). Once i have figured out the three connections I will start on the power supplies. Will start on about 60v up to about 110v (depends on what i can get to work from the pile i have stashed).

Next up will be getting or making a PWM drive. I have a dozen 47N65C3 MOSFETs (650v 47A continous, 141A spike) and will try to make up a simplified PWM for a bit of control. I am not sure i even have the skills to get this to work but at least I will be learning something new and therefore it is never a wasted effort. The interdrive ones are great i reckon, but again, budget doesn't strech that far right now....possibly something to aim for if I don't get this working as is, but that might be a while down the line.

I don't have a variac that would come even close to large enough for this application so i will have to figure out that as we go. Or maybe find one on the "bay" as it would be a great addition to the bench anyway.

For now, I have already learnt a lot, thanks very much for your help and advice. Any further thoughts or advice is gratefully recieved!

Cheers,

Craig
