Hi Chris, I’m sorry to hear about your accident. I wish you a speedy recovery.
About 5 years ago, I broke my ankle. I wasn’t able to go to the workshop for 3 months. It was a difficult time.
The two iron blocks were originally joined together; they were separated using an angle grinder and then machined to the same height on my old Loewe lathe.
A little bit of progress on the engine.
I found two crankshaft bearings in my collection that might be a better fit for the engine. They bring me almost exactly to the cylinder's centerline. However, the split bearing shells are made entirely of "WM 10"—that is, white metal—and the bore is too small. Using white metal without separate steel or brass bearing shells is perhaps not ideal, as the walls would become too thin once the bore is enlarged. In this case, bronze bearing shells would need to be fabricated.
The iron blocks have been glued in place for now, and tomorrow I will secure them further with screws inserted from underneath the base.
