    Similar, in some ways, to the drone engine, above, this is CNCed with (not very efficient?) shaped inserts for the transfers.

    I was interested in that one when it was unveiled and couldn't find it again (couldn't remember the name!) but here is the link to a good animation which leads to other animations.

    Yes, I'm sure it would only be you - however I did of course notice a certain subtle resemblance to something else, but, (unlike you) I am quite a reserved, shy and discreet sort of person, so I decided not mention it!

    Actually i might have figured it out.

    Dick and Carroll stayed at my house when they came out to NZ. Husa, they would have been within a few meters of your house too as they did the Trans Alpine Express, you know the one that goes past your house Glen
    Dick has some more rotorcraft to his name now, one particularly fast vertical takeoff and lading gyro / helicopter hybrid. Not released to the public yet. Real nice guy.

    Any ideas? Suggest circa 1950. Plunger, girder & 4 stroke.

    It's a Motom. Italian most likely 48cc. Pressed steel frame, some had peddles as a moped. Lots of configurations on these, most made in the '50s but they did continue into the '60s.

    Here's a shot of my 1957 Motom 51

    Looks like they evolved from a moped to a motorcycle sometime between 1948 and 1957!

    This thread goes to sleep periodically and occasionally it needs a good swift kick up the arse, so to speak in order to "kickstart" it again!
    I found this gem (actually through one of the ESE posters and although the subject is HCCI this time, this guy is great value!).
    HCCI could still be classed as oddball as it as yet is not used in the present engine scene, (not in the two stroke scene either), but once it has been properly tamed, it could be good.
    Is it in time to save the IC engine from extinction (before electric wipes the slate clean?) - who knows!
