    An unfortunate design, that integrates the cent switch with one of the line-in terminals. We'd have to completely rewire the terminal board to make T4 the star point and T3 the line-in. If it were...

    The brown wire goes to the thermal limiter, and I'd guess that terminal 5 is an integral part of the cent switch. I'll go back to the drawing board :)

    Hmm, RRR's technique might work, if you have neutral in your cable, but it does not disconnect the second leg. You'd have to have another disconnect method, like a plug to be safe.

    many times, the wear on the right bearing is worse than on the left, so the spindle points down. The fix might be to pull the lower bearing shell from the headstock, and apply a tapered shim under...

    You got a lathe so you could turn and bore parts. That can/should include your spindle mount tooling. It only takes a few minutes to open a 1.5x8 backplate up to 1.625x8.

    Instead of measuring the pitch, flip the work piece around and press it against the side of the spindle threads. It should nest perfectly.
