    Rotating Power Cylinder Ringbom

    Should have also said. An increased crankcase pressure will increase engine power as would using a better heat conducting gas. Then it would have to be sealed and again frictional forces would increase. On a small coffee table toy like this it would all become pie in the sky its just a toy too...

    Rotating Power Cylinder Ringbom

    Hi K2, hmm how to answer Agreed a lip seal may be a better alternative but does the friction not increase as the pressure increases. Also Im a tight wads and like to make everything I can The air passage way is lined to reduce heat loss . I had some machinable ceramic in my swag stash from the...

    Rotating Power Cylinder Ringbom

    Hi Jim, its all magic n mirrors :} The engine uses the Ringbom principal but due to the rotating cylinder becomes a marginal thing at best. The passage way for the hot air is a bit long and convoluted and the pivot is an air leak point. It was nearly a runner for ages just no cigar until I...

    V4 Oscillator Motor

    Noggin end sell graphite in the UK P.O.M is also hydroscopic and if you should happen to get it too hot it gives of formaldehyde gas. Delrin is a brand name as is Hostaform and a few others I forget. One of the benefits using graphite for hot air engines is its low rate of expansion and self...

    Parting tool chatter

    When making small gas jets. I drill 0.3mm then swage down to the size needed. It saves snapping those drill bits It is just a simple jig , punch and guide to keep the hole middle for diddle. The wire is easily found I also tend to make batches of 10 and need to make some more shortly cheers
