I got the book last fall for a present from the miss's and built one last fall and finished it last winter.
It was the first time I built this style engine and have to say it has turned out to be a pretty cool engine..I recently received the Atkinson differential engine which I think will be my next engine.
I would recommend the book it was very informative and well worth the price IMHO.
I just recieved a complete set of plans for the Atkinson engine plus plans for a carburetor from Jan Ridder. The plans and technical write up seem to be very complete. Jan is asking for a "donation" of 5 to 10 Euros for the plans , which according to my converter is $6 to $12 Canadian, a very reasonable price. These plans seem to be excellently done, and very complete. They are in Metric, but that shouldn't be a horrible stumbling block, as I will model it all in Solidworks and use the built in Solidworks converter to generate British Imperial (inch) drawings. I have no idea when I will build this engine---Its a matter of how much real work I have, How much fun I'm having with my wife and grand daughters touring around this summer, and how bored I get. This will be one of the builds I do where I won't be able to provide drawings, (I don't want to step on Jan's toes) but it should be a fun build with lots of pictures and commentary as it develops.----Brian
I thought I had better explain that Jan's donation isn't compulsory, but I always give some, purely because his plans, time involved and engines must cost him a fair bit to develop, I actually consider him as a modern day Elmer.
For anyone stepping up a gear from Elmer's offerings should really consider some of Jan's easier engines, then progress onto something a little more challenging later.
John---It would be very crass of ANYONE to use Jans plans and not compensate him for them. I know how much time and effort go into modeling, machining, and creating a set of comprehensive engineering drawings. That is why, as I said in my earlier post that I will not be posting plans of this engine as it develops, because I don't want to step on Jan's toes.
