Anyone on here any good with industrial/3phase/machine electrics? Bought a new to me Smart and Brown 1024, which is in very nice condition. It has arrived and yesterday went through the ordeal of taking workshop roof off to take old lathe out and put new in. When disconnected it had been hard wired and it was just cut off wired on a plug and hooked up to phase converter. It also has a lead that needs to be plugged into a 110v transformer, which I have done. this iS obviously not original and on further inspection it seems that there used to be a small 415v to 110v 100va transformer in the lathes electrical box. It’s no longer there so I’m guessing it shat the bed, hence the need for an external transformer. I’ll sort a proper replacement at some point. AnyWay, when I tried and fire up the lathe there is a hideous buzzing noise and vibration that literally shakes my meagre workshop. I have not a clue what the issue is! It does this in forward or reverse. The spindle turns slowly, not as it should. Ive tried all the possible wire configurations in the plug, I tested the 110 transformer to make sure it works which it does. Anyone have any ideas? Or anyone localish to the Tonbridge/Tunbridge Wells are that knows about these things that would look at it? Paid for of course. I don’t want to mess up the lathe and playing around with 415v scares the Sh!t out of me! many thanks, Joe.
