Frank Boler 10cc 4-cylinder 2-stroke engine

[Shane B SulserParticipant @shanebsulser13156]

Hello:

I'm new top this forum. I am looking for any information about Frank Boler's 4- cylinder engine on the cover of The Model Engineer Vol 103 #2574 Sept 21 1950 issue. I have tried searching the internet, but with no luck. Any help would be greatly appreciated.

Thanks, Shane

Hi Shane, If you search for Model Engineer index you should find a site that has a searchable index at http://www.itech.net.au A search on that for Boler gave me about 10 hits, including the 1950 cover. There is also a 1948 cover of the "Ensign" 10cc engine by the same guy, and references to models of his at exhibitions. He went on to build a working 7 cylinder Gnome engine which won the Championship Cup at the ME exhibition, so was evidently a very skilled worker.

I would have most of the issues found in the search so could easily scan pages for you if you are interested.

If John doesn't have them I may be able to help ! Just give me issue numbers and or date ! Noel.

I've dug out the 1950 issue, this also refers to another issue#2572 with a report of the exhibition where the engine appeared. In that one there is another photo and a description of the engine. If you want to send me with a personal message with an email address I can scan those for you.

I don't know what your interest in this particular engine is, but Dean Clark who posts on here occasionally builds a lot of two stroke model aircraft style engines, including multicylinder, up to a supercharged V12, which you can find pictures of on this site. He would be a good contact if you are interested in this sort of thing.

The editorial comment on the front page photo mentions a promised article on the engine, unfortunately this does not seem to have ever been written. So probably there are no drawings available. The best way to proceed if you want to make something like this would be some study of the old Model Engine News site, no longer being updated but still online. Model Engine News

Otherwise you could see if you can contact Dean as mentioned above. If he doesn't respond to a message here I could give him a ring…(he is local to me.)

Thanks for your help, John.

I did checkout the Model Engine News site. I'll have to look around on there some more.

Finding anything on this engine might be a quest.

I will contact Dean Clark and see what he information he might have.

Regards, Shane

Yes, what I have in mind is that you might be able to find enough information to allow you to design an engine like the Frank Boler one, if not exactly the same.

regards

John
