Sideshaft i.c. Horizontal engine

[Brian Rupnow]

Flywheels are broached and all is well. Nothing broke, flywheels and keys are assembled on crankshaft. Now I can go to bed.

cant wait to see it run

 

[Brian Rupnow]

So here we go guys and girls. We have a runner. I still have a few adjustments to make, but overall I'm very happy. It took very little to get it running. I am confident enough at this point to sell a complete set of plans for this engine for $25 Canadian funds. On a scale of 1 to 10, with the Webster being a 1 and Malcolm Strides Lynx being a 10, I would classify this engine at about a 5 in terms of difficulty to build. Contact me if you wish to buy a complete set of engineering drawings as .pdf files. I will be doing more adjusting and tweaking, and will be back with a better video, but there will be no more changes to the engine itself. I have a Traxxas Pro 15 carburetor on right now, but will include a complete set of carburetor drawings with the engine in case you wish to build your own carburetor.---Brian

Con grats Brian on another running engine sounds very smooth

And here we have the engine running after a bit of "tuning up".

I will take a set of the drawings please Brian. No rush, but how would you prefer I did the tx from the UK?

Earl--I messaged you with details--it will be in your message box on this forum.---Brian Rupnow

Congratulations on another great runner, Brian!

Can I ask what's the bore and stroke of this engine? I think I recall you saying it was a 1" piston, but not the stroke. I need to think it over.

 

[jacobball2000]

Where did you get the broaching tool?

 

[Brian Rupnow]

Bob--1" bore, 1 3/8" stroke. If you go back to post #10 of this thread, you will see the most complex part of this engine. If you are confident that you could machine this part, then the rest of the parts are fairly simple.

 

[Brian Rupnow]

Jacobball2000 I got the broach thru Fastenal. You can also buy them from KBC tooling.

I really like this one too, Brian. Great sound and runs and responds so well to the throttle.

Lots of interesting things to watch while it is running.

Congratulations and Thank You for posting,

Thank you guys. I am very pleased with this engine.---Brian

When I built the gas tank for this engine, I incorporated my anti backflow valve into it. Since this is a throttled engine and not a hit and miss, the only advantage that I could see is that on cold starts the fuel would be "right there" at the carburetor, so I wouldn't have to go thru prolonged choking of the engine to get the gas all the way from the tank up to the carburetor. I am very pleasantly surprised---The engine starts immediately on a cold start with no manual choking being necessary at all. Just thought I would pass that bit of information on to other home model engine builders.---Brian

One thing I have learned over the years is to replace tool when the unfortunate things happen. I might not ever use it but it is in my tool box because I know bought it and expect it to be there when I want to use it. Another thing it will cost less today than what it will six months from now.
Enjoyed all you projects and don't stop anytime soon.
Cheers

Good idea Nelson. After I finished this engine, I toyed with the idea of putting a governor on it. However, the engine runs so well that I have decided not to mess with it. I may build a governor as a "stand alone" unit which gets driven by this engine, but is not an actual part of it.
