Hi... I'm building the 'Hercules' which is basically the same thing (also by Bob), but smaller.
So far, I'm doing it all 'by hand' (No CNC), but I am playing with the head design in INventor 8. As is my nature, I'm redesigning the whole thing as I go, so its slow going. Currently I'm taking a diversion to build a crank grinder.
The plans and castings are worth the money he asks, though the dimensions tend to be scattered and not all drawings agree with each other. I tend to redraw them in cad so I can 'test fit' the parts.
There are several good shows around the country, and some folks have made some truly amazing engines... |
