I echo some of the comments about its action. Fascinating.

Great job!  :ThumbsUp:

Hi Craig.

I was recently poking through the photo archive from the Anson Engine museum, I spotted something you might be interested to see.

I recall you mentioned about the piston being " blown " out of the bore under certain overcharged circumstances.

The photo is of a 1 horsepower engine, note the plate that is bolted across the mouth of the cylinder. On others there are Rubber arrestors bolted to the sides.

Cheers Graham.

Thanks Achim, Dave, Graham, Zee, Jo, Rudy, Kim, and Chris for your comments.  Thanks also for everyone else silently stopping by to see the progress.

Itís been an interesting two weeks.  As of the last posting I had two objectives to complete.  Firstly, I needed to clean up some of the parts that were roughly modified in order to get the engine to run fairly well.  There is no use in making and remaking parts as a ďfinalĒ part when you just donít know if the part youíre making will help (or hinder) the progress.   Secondly I wanted to get the engine running well enough and get the governor modified so that the engine would be controlled by the governor.  I succeeded in both these endeavors.

Iíve posted a rather lengthy video that describes the engine I am modeling and then the model itself.  The model is started and run in the back half of the video.  I start the engine with the starting lever and after a while, if you watch closely, you can see where it gets peppy enough a few times for the governor to lock out the firing cycle and allow the engine to coat a while before permitting it to again take power strokes.

Iím very pleased with regard to how this engine turned out.  When you design an engine you expect it to run but you just donít know how well.  In that regard, this model has met all my expectations.

You can see the video here.

My current plan is to go through the drawings one more time, checking for last minute changes and then package them up and make them available here on MEM to anyone who might want to try building one.

Thanks for the complement Roger.

Iíll give you one more video before I close the book on this model.  Itís been getting some more running over the past few days and the cylinder/piston ring seal is improving so apparently the piston ring is seating.  I also found that spraying some WD-40 in the air intake seems to lubricate, break up the crud,  and help seal the cylinder really well.

The engine now runs, I would expect, much like the full size would without load. You can see in this video that the engine fires once and with that one power stroke gets the speed up where the governor locks the engineís firing mechanism out from taking additional power strokes.  The engine coasts down until the governor unlatches, then the engine fires only once to get up to speed where the governor again takes control.

Iíd think the model, at this point, is emulating the full size pretty well both aesthetically and in operation.
