There's no substitute for cubic inches (or dollars). Getting the crankshaft ground to the right stroke and rod journal diameter is the biggest challenge- - - -that's why I bought two crankshaft grinders a couple of years ago. Maybe someday before I get too old and feeble to work in the shop, I'll get everything up and running and start turning some of these Rube Goldberg pipe dreams into reality. I don't have any "trade secrets"- - - -I'll gladly share ideas and dimensions with anyone who will take the time to communicate with me!
