    So i put the 9v battery on to Pin 2 and Pin 7(earth) as suggested, then pressed the one of the buttons on the switcher, then spindle starteded but got faster and faster until i took my finger off, didnt want it going mega fast so wimped out lol

    Z and X are nice and warm, not hot now, so might stick with 18k resistors for now

    Thanks for the help guys, much appreciated.

    Tried two AA batteries giving 3v and again worked, not as fast so i will try just one like John S Suggests.

    Just need to work out how i can get this button to be pressed Via the PC.

    Thanks again

    Use a breakout board with a relay on it, or if you already have a BoB then an add on relay card

    the contactor on my boxford 240tcl has a 240v coil, so be carefull around it.

    Looking at the 125 schematic, it's 240v as well.

    Yeah I'm not happy about pressing the contactor myself.

    So wanting to keep with the "not overly exspensive" side of things,

    ive seen this

    Think it should be fine for the 125

    She has already stated the lathe is far too noisy hahaha, unlucky!

  9. whats wrong with a Uniport or an optoport ? cheaper and UK based...
