Hello Colin and others.You musy be quite an expert by now on lathes Colin, keeps the brain active. I rebuilt my super seven several years ago after have the bed reground. I took it to pieces and it was 6 weeks before I had the oppertunity to start reassembling it once again, that really did tax the grey matter. I made myself a test bar with a 2 morse taper and about a foot long to ensure that it cut parallel afterwards.Back to the repulsion motor they were always noisy and as some one else mentioned the com is shorted out by centrifugal action then runs as an induction motor. They must have been expensive to make and purchase, but would start under some load such as compressors.I remember a lot of butchers freezers had them,I don't think they are available new any more. A couple of years ago I wanted information about a Brook motor,I think it was a new centrifugal switch,I can't exactly remember, howerver I rang Brook/Crompton Parkinson who said ring this number which turned out ot be Doncaster. They said you need this Tico number and they said we don't make the spares any longer.Apparently Tico is an electronic firm who just bought out Brook and other motor manufacures here in UK. Incidently I gave away my copy of "Keep your Motors Running" a couple of years ago,but kept "The Induction Motor" book. As you will most certainly know Brooke made a single to 3 phase converter based on an induction motor and capacitors, we fitted a few on farms. We fitted some big ones made by Westing House, Two lines or phases in 440 volts and three phase out 440 volt, big and heavy. Sun is shinning here in sunny Scarborough.Bye now must get working.Ted
