    An old exercycle fly wheel, will become the A section drive pully sandwiched into the drive shaft assembly for starter purposes. Three phase motor as the starter on a hinge arrangement.

    Hey Neil , been there done that with the " flip off the belt once its started thing ". A real PITA.
    Use a small auto trans flex plate and a starter motor , way way better.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    Ahr, you havent seen the finished product yet.
    I dont want a 12V system, I want 480V 😆. I want the ability to motor this engine for a time, might be a bit hard on a starter motor.

    Yeah, they are not very strong, its barely strong enough to just hold this end of the drive shaft. All my wooden boxes are in use, ' storing stuff ' 😆.

    Ahh, the good old bottle ones were great. I managed to acquire one before they fell out of fashion. Well before. Every engine I have split and reassembled has been done on that and a million other uses. Super strong, lots of holes for shafts and won't scratch anything. Heck now I'm concerned that I should take better care of it.
    Don't you look at my accountant.
    He's the only one I've got.

    Dirty old exercycle flywheel is now a 400mm pully.

    You're right about the longevity or lack thereof of a starter motor.
    Of course Wobbly is right too: belts are a pain. But we don't need them. And since you are already planning a hinged start motor, take a look here:

    The kart tyre was hydraulically driven and pressed against the flywheel, because hydraulic pressure happened to be available on that dyno, but of course you can use your 480V instead. Come to think of it: where do you get 480V? In the old world we are happy with 380V...

    The problem is, only being able to use whats available within my two scrap heaps.

    Dyno

    Frits,
    What is under the red half-round guard shown in Koene-3 and Koene-4? Break away torque limiter or a clutch of some sort?

    You gotta have a one way clutch somewhere in a direct driven engine dyno setup.
    Just imagine the chaos caused by the huge drum inertia , continuing to spin everything , if for some reason the engine siezed or the gearbox drive failed.
    I have discovered that a cheap , small one way clutch used on tractor PTO shaft outputs works perfectly , and is easy to adapt.

    One of the benefits of using a suitably sized 3 phase synchronous motor, is that in addition to providing motoring ability, can also be used as a steady speed state load absorber. Obviously up to the rating of the motor and the available electrical power supply. As an absorber it can turn the meter backwards. Imagine that, a 2 stroke engine powering NZ’s energy grid.

    Yeah, a sprag somewhere might be useful, certainly with an inertia flywheel, but how could you start or motor the engine as Fletto is suggesting? Maybe just rely on the belt shitting itself? Or keeping his hand on the clutch lever or motor pivoting position, relying on Neil’s ultra-sharp race tuned reflexes.

    Possibly one sprag clutch to keep the flywheel from over-running the engine and another sprag clutch (before the one for the flywheel) in the driven sprocket of the starter drive?
