    This does look like a nice engine.

    Thanks for posting the plans for this engine.

    I just finished building this engine it was fun and it runs great. I am new to the hobby with this being the first engine I have built. I sure have learned a lot during it's fabrication. I'm sure the machining on this engine is not the greatest . However I'm learning and the engine does run great.
    My next project is the Webster Engine Works 4 cycle Gas Engine.

    Great site
    Thanks Bob Parker

    Hello Bob, and welcome:

    If I may ask a question. Did you use the 2-56 thread size that is shown in the drawing?

    Thanks,
    Kenny

    Hi Kenny
    Yes I did use 2/56 in areas that the plans called for. It seems to work.

    Wonderful work Kenny, they are really coming on nicely.
    I see you used the split web design then, did they work out ok for you?, or did you run into any problems, just to let the other builders know if it is a viable proposition on these types of engine.

    I still haven't found a thin saw blade to slit them. They are a press fit on the pins but I feel they do need a bolt with a slit. The other thing is I added a support between the cylinders and another one on the outside of the flywheel. I used a #2 center bit for the main shafts and 1/4" music wire for the shafts. That gave me the press fit. The shaft is extended past the flywheel so a drive pulley can go on it to run something. It took me a while to find the little bolts like Bob used. The steel bar in the pictures is my failed attempt at a one piece crank as I took too deep of a cut and bent it in the middle. As you can see, there is 5 crankshafts. One of them will be split in half so I can have two one cylinder engines. I have a crankshaft truing stand and they rotate true. I still need to make some fluted columns for the rest of them and couldn't bring myself to possible causing damage the ones that are made.

    Hi Crankshafter and Kenny,
    Nice photos and very nice work.

    Kenny, I checked out your photobucket album. Are you building two of these engines?

    Thanks for posting the plans Rake.

    Hi Phil,

    I am making four engines.

    Two of them will be will be close to the drawings with outside cosmetic changes. I don't have the tooling to make them as per print.

    I want to make the spacing wider between the cylinders on the second two so each cylinder will be separate from each other. That is why I chose that type of crankshaft as it is just a matter of making the center shaft on the crankshaft longer to push the cylinders futher apart.

    Thanks for the compliments guys,

    Kenny
