That looks nice. I'd like to see more info on how you made it. I'd also Like to know more about the engine because it sounds like a neat project

Yikes, makes my palms sweaty just contemplating such a task. However, you seem to have done a lovely job. Nice work!

I start the building of this crankshaft in april, and I hope it will be finished around the end of september.
A have allready 100 hours of direct work and 80 hours of "side" jobs like building of a grinding head, special tools, etc...
I aso have more than 100 pictures.
When this piece clear, I will post pictures and comments of mashining process.

Looking very well, have been in a similar situation, the feeling when the crankshaft run well in the bearings after many hours of work, is very satisfying.

That crank shaft is a thing of beauty! I look forward to you sharing your methods here. That is one complex piece of work.
