Default Re: Metamec A909 clock- broken coil

I made a coil winder using a lathe on very slow speed, I fitted an inverter several years ago. I made a ring using Tufnell which fits around the partially open chuck jaws, in the Tufnell I inserted/fitted a small magnet. In between the ways of the lathe bed sits a small block of wood, which has a reed relay attached to it. I did a surgery job on a £1 calculator so that as the lathe rotates, the turns are shown on the calculator display. It works both ways, I've wound coils for motor starters using used wire and removed windings so that 415 volt starters will operate on 240. Ted
