Been working on Sheet 5 of the Webster. Got the flywheel, crank (still needs some sanding), crankshaft, crankpin (not finalized yet), and bronze main bearings, pretty much done. Photos below of current state of build. Now on to Sheet 6, the piston and oil tube. In my other threads on this first I.C. engine build, I asked questions on different aspects, and I will continue to do so rather than one build thread that would go on forever with all the questions I have had. I do very much appreciate all the help I have received.

Edit: Decided to go with my original plan of a cast iron piston fit to size in the steel cylinder. Before the edit, I was asking about alternative to a direct fitting piston. Actually, what kind of fit would be best for a cast iron piston to a steel cylinder?
