Barry,
Thanks again. You were so right on the cutter. It was way too big. I look back on the crank machining and even with all my mistakes on the first 3 and botching them up, I consider it a learning experience. I learned how NOT to machine a crankshaft. The lessons I learned on the 4th crank I think will stay with me a long time. I've built plastic and balsa models for over 65 years and thought I had the patience part down. NO, the crank taught me MORE patience. Now I'll be working on the cylinders. I still have to bore out the 3/4 inch hole for the pistons. I know there will be some adjustments needed to get everything into alignment. I think I'm going to take some time from the V-8 and mess around with the 1/4 Scale Myers/Rider-Ericsson that's almost completed. When I was at the NAMES show last April, I was told that making the displacer piston out of BBQ grate cleaner (a stone like material that's a lot lighter) would be a better approach. Will keep you updated.
