Murray's Hypocycloidal Engine - Antony Mount

Whoopee doo!

It wasn't that the little inflator didn't have the puff!

It was that I should've retarded the timing by about 10 degrees instead of cracking the inlet ports at the deadcentres. Thunk that thought drifting off to sleep last night after another pointless, meandering episode of Dicte on the telly.

Carol's delighted that I don't now have to buy an expensive compressor... (we'll see later)

Anyway, here's a video of it running:-

That runs nice and slowly, smooth as well even with what is quite a small flywheel.

You have done a neat job with the metalwork so leaving bare would certainly be an option, If you decide to paint than I think these early engines look good in a satin black which is not unlike the finish already on the flywheel, gears and base plate.

Thank you for that. I think I got a bit lucky - there's still a minor tight spot at about 5 o'clock that I think can *just* be noticed in the video, once you know it's there. I'm reluctant to try to fix it in case of creating other issues.

When I get to it, I think I might get smoother running from my other engines if I re-examine the timing to see if it's too close to the deadcentres.

Nice work Mick, been a good thread this some interesting input

Geoff

Nice work indeed.

Thanks for the kind words.

What a lovely piece of work, well done.
