While clearing out the garage I came across one of these in a pretty disgusting state.. Motor, frame and 2 spindles, one for bores and another for external.

It states model M2 plus the voltage and little else.

Does anyone know anything about them ? I could ideally do with some idea of motor power and rpm

Doh – I thought I had clicked on workshop equipment. Maybe a mod could move it there ?? Pretty please.

Just in case anyone has one and the name is different or has worn off there is another one on ebay at the moment. Not mine and less rust

Looks like the rest of it will do nicely to Michael. I had completely forgotten that I had acquired it and was thinking about making another but light high speed motors with reasonable power levels are a bit of a stumbling block. Hard to find or rather expensive.

It should also do for titivating tools.

I suppose I was hoping some one had a manual for it. The motor looks to be a similar size to the Wolf one but without actually seeing one it's hard to be sure. That one does mention current draw 2.2 amps but no mention of power. 8000 rpm. These things come with all sorts though. I can measure the rpm but feel that I had better dismantle and clean it all before running it. Spindles too.

Other than that the bearings all need to be accurately aligned even in the motor there isn't really any difference. It all needs to be well balanced to avoid vibration. There seems to be 3 screws locating the front bearing on the motor positioned in a way that they could be used to centralise it to the rear. Or maybe they just clamp without distorting the bearing.

It looks like the spindle bearings run in oil going on the oil caps fitted to them. Some universal grinders use a labyrinth to keep the oil in – sort of "cooling fins" on the spindle and on the bore ahead of the bearings. In terms of making one I intended to bore and maybe ream all the way through, add 2 circlip grooves to position the bearings and then add preload with disk springs. That way all machining is in one setting so will be accurate and the disk springs will smooth out the slight run out in bearings and maintain a decent pre load with temperature changes.

Easy but as I mentioned a suitable motor has proved a stumbling block. Turns out I have one. I hope. The alternative was phone up Parvalux and order one but what power? I probably wouldn't like the price and there is also the point of just how smoothly the lathe needs to run to make these things useful.
