    I've wondered about the same thing and agree there is some point at which the flywheels will rotate out of alignment. A locking taper is used, and the nuts used on the early engines are tightened a couple hundred ft-lbs, but engine rebuilders invariably find them out of alignment. Later engines had the tapered pin pressed into the counterweights and some racers even welded the ends of the pins to the weights. - Terry

    That is an awesome build. Thanks for sharing this great adventure. Do you have any build videos? That would be awesome to see. Your next project is going to have to be awesome because you have set the bar extremely high. Thank you again.

    Hey Terry
    First thank you for the complements on my design, but hats off to you, for the transformation of my piece of coal into the diamond you have created. Not to mention the fantastic, how to build documentation you have created. You have created a piece that should only end up in a museum. I am proud to be a small part of it.
    Congratulations on a great build.

    Hi All
    A quick query
    The flywheel starter pulley 3/32 slot is shown on the L/H side on the detail drawing but on the R/H side on the assembly drawing.
    Which is correct?

    If you use the camshaft specified in the drawing package, the engine will run counterclockwise when viewed from the cam box side of the engine, and you would place your starter rope slot accordingly to start it. If you use the camshaft that I designed, the engine will run clockwise when viewed from the cambox side of the engine, (the same direction as the full-size engine), and your starter rope slot location would have to be reversed. Be aware that if you use my camshaft, the oil pump's inlet/outlet locations will also have to be swapped to accommodate the direction change from the original drawings. Best of luck... - Terry

    Thanks Terry
    I am making it to the downloaded drawings, so should the slot be on the right or left on that detailed drawing of the flywheel starter pulley?

    Graham,
    I don't have access to the drawings right now, but in that case, standing on the flywheel side of the engine, you'll then want your starter rope slot on the left hand side of the pulley so that when you pull the rope upward, the engine will be rotating clockwise as the rope leaves the pulley. - Terry
