@rattler I did ask about the cranks this morning, basically he was ever so slightly shimming the bottom of the counter weight between it and the blocks of steel used in the press. Also said it would go in and out of the lathe up to 50 times, he would hold it in his hand and give it a whack with a soft hammer, then back in the lathe. He also said a jig is the way to go if only working with on style of crank, that's why he does it the way he does, always something different coming along.
He said he has a 2 stroke motorcycle crank to do as some point in the future so I asked if I could get in on his process. So I will try to attend and take some pictures of the process he uses. Sounded to me like a rob Peter to pay Paul kind of a thing as like I wondered, where are you going to find connecting rod bearings? SS
