Hi Noel, Thanks for the wiring instructions. I feel a bit uncomfortable about the asbestos in the switch as it looks very tatty so I have contacted Santon switchgear Ltd and they have an identical modern equivalant switch with the same code number accept with an added P ie SRP 137KA instead of the old SR 137KA. They have advised me that the switch is the equivalent so I'm wondering about getting it. I am already getting the clutch thrust brake pad replaced at the moment at a surprisingly resonable cost so will feel more comfortable using the lathe again. From your very knowlegable advice you've given me would I be correct to go down this route. Many thanks Martin
