I am a silly billy. I accidentally left the traverse drive engaged and forgot about it. the table came up against the stop and the drive started to slip, I dont know for what period of time. It was longenough for the slip to become a permanat feature even when the bed is not up against a stop. The drive and gear box is one of the early with the change speed lever sliding up a slot and swinging into engagement at trhe appropriate slot. What I used to think of as a Norton type gearbox(not the motor bike type!) Sadly the photo copy of the hand book that I got from lathes.co.uk does not have an exploded diagram of the drive arrangement. I have removed the top plate whith the change speed lever on it - cant see the point of slippage there. I have removed the motor and the worm wheel appears well connected. I have removed the side plate with the hig/low knob on it and cant see where to go from there.
Can any body out there offer advice as to what to do next.
It was late and I was dropping tools when I gave up for the night! Andy Cawley
