Tel,
Very interesting engine.
Is this all "Scratch built" or are the plans and castings for the frames from a purchased casting kit?
Also what height is it?
Thanks
Dave

Totally built from the ground up mate. I actually made the pattern and cast the frames about 4 or 5 years ago, and the whole project then lay fallow until this year. Then, just after I started work in earnest, the half beam project came along and disrupted things for a while. There were no drawings made, other that a couple of rough sketches to figure out things like the valve dimensions and the eccentric set up. There are a bunch of progress pics, and a bit of video here |

Indeed they do market a double diagonal, but close inspection will reveal that it is quite different to mine. There is a fairly comprehensive set of pics of my build here  for anyone that's interested. |

Yes the trunks guides are different but full marks for a smart design mate
