The crank shaft is almost finished, its been hard work as only small cuts at a time can be taken so as not to strain the setting. Its only held between centres in the lathe and if a tool were to pick up it would be disaster. As it is I'm very pleased with it. I need to reduce the weight a little and I've been studying some pictures of the Saito twin cylinder crank shafts and the balance weights have been shaped as a semi diamond on both sides ie where the counter balance weight would be. So I'm going to do the same.
