Building My Own Two Stroke Engine
by Paul Ellis
I am building a Ricardo-type sleeve-valve two-stroke engine with BMEP of around 460psia, 50cc's per cylinder and 15,000rpm. Can't disclose too much info, but I do use rapid prototyping. UK for Thermojet waxes and castings, China for prototype machining, Korea for specialist components, Canada for other bits, Germany for specialist alloys (made to order).
We use Solidworks for our 3D modelling. We have UK and International patents pending. I also build custom cycle frames as a hobby.
