Brian........that "Hubcap/Fancap" really adds a lot to the look of the engine! Nicely done.

Thank you Jim. The fan needed something to dress it up a little, and that worked just fine. That's why I keep all the "short ends" of stock that I have used for something else. I use it up right to the point where there is nothing left to hold onto.---Brian

The whole job worked out very nicely, Brian!   :ThumbsUp: :praise2:

I've enjoyed, again, your engine build and you can bet I will follow along on the next build. Whatever it is!

Brilliant Brian, you have this down to a fine art now. It is so stable yet responsive.

Thanks guys. I don't think there's anywhere left to go with this engine now. If the weather ever warms up I want to take it out into my main garage for a good long endurance run. I don't have any ideas for further improvement/changes to this engine, so now I'll just have to wait and see what inspiration hits me next.---Brian

I have recently had a request for a set of the plans for this engine from a gentleman in USA, so have been busy as a Boxing day Beaver this morning converting all of my Solidworks files to .pdf files. In my opinion this is one of my more interesting engines, and as you have seen by the posted video, it is a great performer. If you wish to buy a set of the plans to build this engine, I charge $25.00 Canadian funds for the plans, all saved as pdf files.---Brian

A gentleman  in SOUTH DAKOTA just finished this engine, based on the plans I sent to him. He discovered a few tweaks that were required to the drawings, but he has a runner, and it looks really good. I have updated the drawings to reflect any changes that were required. So--now there are two of these engines in the world. Mine and Jacks. I think this is one of the prettier engines I have designed.---Brian
