    There are several 1N4001 (1000 volt) blocking diodes on this board. Rod, 1N4001's are only
    rated at 50 volts. 1N4007's are the 1000 volt ones.Ian.

    Andrew, I was only guessing about your diagram. The point was that the cams are at "about" 90
    degrees not 180.Ian.

    With your settings Brian, shouldn't the cams be at exactly 90 degrees, ie 180 crankshaft
    degrees. Even in Ghosty's picture they "eyeball" at 90 degrees.Ian.

    Looks like a fun ride whatever it is! No apparent brakes always makes it more interesting.

    Always a pleasure to watch a real craftsman at work, no matter what he is producing.Of course,
    that applies to Terry as well!Ian.

    I have always wondered at U.S. tv shows like CSI and Bones which routinely quote metric units
    for distance and weight. I thought they were just trying to be "scientific".Ian.

    By the look of your diagram, none of them are important for the running of the motor. They are
    all only noise suppression caps to try and cover some of the natural arcing at the commutator.

    Well done, I hadn't thought of the protective sleeve idea, but I guess it may be how the very
    high temperature probes are made anyway.Ian.

    I would be very surprised if the supplied probes are capable of surviving 1300 degrees. That
    figure is just the maximum value that the meter can indicate, think full-scale on an analog

No matter how much you push the envelope, it'll still be stationery.
