9 forum posts 8 photos	Thanks Martin, I'll have a look. I've got the manuals available on the group, although the drawings available are certainly helpful, even if not entirely clear! I bought the lathe with 2 booklets which I believe are the print from lathes.co.uk. Just thought I'd shoot an update with the switch plate roughly mounted, needs a lick of paint and the rev/off/fwd decal taken from the barrel switch adding but it works for now.

The new one, even though it is a higher power rating, is lighter than the old motor by a significant percentage. Since the tension on the belt is a result of it supporting the weight of the motor on its hinged support it is more prone to slipping with the new motor and I have to have a couple of heavy lumps of metal on top of the motor to give sufficient tension to the belt. Maybe if the Model A is similar you do not have the original heavy motor on your machine. Martin C I have a Model M too , and the same occasional slippage .. that never crossed my mind ! It does have a hefty old 2hp Single phase motor , but i'll try that extra weight trick ! Or a brake shoe spring perhaps. I've been putting violin bow resin on the belt ! I did see a Fordson Major PTO driving a sawbench with a flat belt and the farmer had a stick of resin ? he held to the belt .
