Third pic: The bottom of the crankcase is pulled, revealing the crankshaft and rods. The crankshaft was lathe turned using a bar of normalized, hot roll, medium-carbon steel. Not heat treated and somewhat soft, but this engine is designed for casual use, not hundreds of high-speed hours!
Final pic: One of the trickier parts, the tiny camshaft. As published in SIC, the prints produced a cam which would have run the engine in reverse! This first cam drove me nuts while I was trying to time the engine. Ultimately I was convinced that the magazine was in error, and sure enough, they were. I wrote a letter to Bob Washburn, the publisher, who forwarded it to P.E.L. (Eric) Whittle, the builder, a remarkable IC enthusiast living in the U.K., who verified the error. Of course I needed to produce another cam. So now I have a pair of camshafts, one for forward, and the other for reverse operation!
The engine is completely cleaned, lubed, and back together. It looks nice once again. I hope you guys enjoyed the pictures.
