Sphinx gas engine.

[Alyn Foundry]

Hello all.

I have attached a video of my Sphinx engine that I designed and built 31 years ago.

<a href="https://www.youtube.com/watch?v=0pxNlFMT24I" target="_blank">http://www.youtube.com/watch?v=0pxNlFMT24I</a>

There were many small changes made to her over the years like Hot tube ignition from HT spark and the final exhaust valve extension to prevent bending.

It has a bore of 39 mm and a stroke of 2 inches. Metric bore to suit Honda piston and rings that were first fitted.    We have all been novices........ 

The " Star " wheel is borrowed from Horace Robinsons 1890 patent for his " Oblique " engine. I half scaled his 1894 patent epicyclic gear that followed from it.

I hope you enjoy the video? Feel free to ask.

Kind regards, Graham.

Quick Jason another horizontal Hit and Miss engine you need to put on you build list. I am sure Graham won't mind if you paint it red

Hi Jo.

I think Jason would make a better job of a build too. I like Red.....

Most of that engine was machined on a little Tyzack lathe that Vincent loaned to me. The bed was machined for me by AWR engineering services. Alex W Rouse became my engineering mentor for quite a few years.....

That engine was the steepest learning curve ever.

Kind regards, Graham.

Well I have not done one with the star wheel arrangement and don't have a blue engine in my collection so.....

Nice engine Graham and the fact it stopped part way through was good as the star wheel can be seen in its simple elegance

Another beautiful engine Graham.

Can't say I gave ever seen one either Pete. It is an interesting mechanism though. Seems to work very well too. Very nice engine Graham.

Hi Graham, a very nice engine. I do like the valve mechanism, good to see the operation so clearly.

Hello All.

Many thanks for your kind remarks.

Just to remind folks that the USA had some pioneers.....
