Perhaps if they didnt cast them but made them out of a decent material they might have been in business today.....But then perhaps "pig will fly"......and if twins are a problem "Stay single"

In an article in JAMPOT magazine some time ago the factory metalugist stated that the foundry did supply a batch of defective crankshafts but they were recalled & few, if any, got out. I don't recall if he said what size engine they were for. Cheers, Don.

Dear Roger Jenninger, Stuart Smith and Markus Graf,

What is the current status of the club's venture to manufacture G12 crankshafts? This has been an extremely long lasting project.
I received my alternator crankshaft a few months ago (6 years after ordering, I think) but still have a dynamo crank on order, and would like to know what's stopping the completion of the run? Where are the semi-finished cranks residing now?
