Sideshaft i.c. Horizontal engine

[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

Terrific!

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

A very fine runner Brian and I must say that it does slow very well

Hi Brian, congratulations on another great runner.

You never cease to amaze me.  It was already 20 March this year when you posted that you were playing around with an idea to use some helical gear that you had.  Now, only 27 April, you have designed and built an excellent runner.  You must be quietly sharing that alternative universe with Chris.

But now, what would it be appropriate for that engine to drive?  Such a nice engine needs to earn its keep.

Thank you, fellows. I am very happy that this motor came together so quickly and started so easily. The amazing part about this is that the one week delay in getting my 3/32" broach didn't hold me up at all. I just kept forging ahead doing all of the things I wouldn't ordinarily do until after the flywheels were broached. Once the broach arrived here, it was only a couple of hours until I had the engine running.---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

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.

I looked around my shop for flat belts, but I only found this short little guy to run my over-center clutch.

I try to post a video of my engines working once they have been set up and tuned. All of my engines have to be capable of earning their keep around here by working at something. They work on a number of nifty things, but this is one of my favorites, the sawmill. The sideshaft engine seems quite capable of running the sawmill with no hesitation, so here we are, sawing some lumber today.---Brian

 What a sweet display Brian! Clutch, sawmill, & sideshaft engine with the governor!

 Just fantastic!

[Brian Rupnow]

I had hoped that this would show the governor working, and it does, but you have to be quick to see it. At 0.26 seconds into the video, just as I engage the clutch, you will see the governor move the throttle linkage to give the engine a little more throttle to prevent the engine rpm from dropping when the load of the clutch is introduced.

[Johnmcc69]

Yep, you can hear the engine load & recover.

 Mission accomplished!

 Great stuff Brian!

Thanks John. There are a lot of hours represented on that table top.
