    I started looking at these prints and wondering if someone could help me out. The inner piston has the steam ports around the radius and they are not centered?? Why would that be?
    one side is .046 and the other is .097

    Stew I studied your prints and you put the slots on a radius and they are centered.
    Does anyone have Ernie's contact? Maybe he could explain...there must be a reason.
    thanks

    Hi

    Its quite some time since I built the Dake engine so the details are a little hazey I can remember finding an animation of the engine and I used that to work out the details of the valve ports just kept stopping and starting things and drawing it out and doing a paper cut out and trying it till I had something that I thought would work. If you search enough on the net you will see that the ports don't always look similar on every engine I think the Dake company must have tried different thing to try and get the best performance from there engines.

    Not quite sure what you mean but the ports were bean shaped and distributed around the centre and they do work.

    Hope this helps
    Stew

    A little late, but I thought I would answer this question.

    This project was started 6 to 7 years ago and was going to be presented in a magazine. I do not remember why, but the drawings did not make it to publication.

    I worked with the gentleman who had the original engine/model engine to draw up the plans. Although I worked with him for maybe 6 to 8 months, I can not remember his name, but he was very detailed oriented in translating his engine to my drawings.

    Concerning the ports all I remember is the following:

    1. He took the dimensions from the original

    2. I remember asking a question concerning this, and he stated a reason for the “unusual” configuration, but I do not remember exactly what he stated.


    So basically, I am no help at all. Lol
