Kirk,
The plans are very well done, but double check everything. Assemble it in your mind before making a part to ensure it will fit correctly.
I used one for the basis of my commercial units shown above, with loads of mods to it, and there were a few basic miskates that would have caused problems if I hadn't found them beforehand.

Bogs,
Thanks. I've been to the jpduval site and downloaded a few of his drawings. Think I may even have downloaded the one you suggested. I remember the 3D drawing of the valve portion. I think I can use parts of that design to build an engine. Have been going over it in my mind and was going to ask you how you would go about putting a piston valve chest on a round cylinder engine. Problem solved.
Hopefuly this weekend I can get started on the frame. Have some ideas I want to try out in making some parts to see if it'll work.
Bernd
P.S. I did download from your rapidshare. Thanks.

Bernd,
Making your own design of engine is rather easy.
Pinch the idea from someone else.
Just joking of course, but if you can understand how the valve system works, it is very difficult to design an engine that hasn't already been done before. So basically I look to see if there are any plans that suit the size I want, then use the port timing in my own engine. My piston valve engine did in fact come from my own dimensions and working out, and I have no reservations if someone was to use them.
Over the last 200 years or so, everthing has already been thought of, even a lot of new designs are only modified old ideas.
So don't think it is wrong to use other peoples dimensions and working out, all you are doing is saving yourself a lot of hard work getting to the same end result. Using that method, I could most probably get a working sketch to make a wobbler in about half an hour, and it would be guaranteed to run.

John,
Exactly what I was going to do. Find out how a piston valve works by using somebody elses design and then adapt it to how I want to use it. You were the first one that has written a complete write up on how it works and how to make it. So I was going to use that valve design only in a twin cylinder engine that will be sepaerated by about 3 to 4 inches but still have a common drive shaft.
That engine from jpduval, I had already found that site and had a copy of it downloaded and printed out. I like the crosshead design on that engine, so I'm going to attempt to use it.
Now I just need to study how it all operates when assembled.

Bernd,
The steam control valve off my piston engine will work perfectly if connected to that engine. Might just need to change the pipeworks route a little.
