The penultimate pieces - then just the shim steel ratchet springs to make, and assembly can begin.
Well it's all done - the small spring ratchets proving easier to make than anticipated. A good clean down of the bench are and it's time for the best bit of the build - assembly.
A close up of all the parts for one engine.
Finally, an assembled engine. Very pleased with the make up - just the merest fettling on the big end that was just scraping the case wall.
The ratchets were 'blackadised' using Jenolite 'Cold Black' .
Together with it's smaller brother - a Russian made version of the original 2.5cc.
All three.
