Ok...I got some time in the shop finally More crank disk "B"s and I cut the crank pins. The pins need to be drilled and finished to length
When I inspected my first crank disk, I found it was out of spec, so I'll need to crank out 1 more tomorrow.
progress!!

More nice bits :ThumbsUp: :ThumbsUp:
Even with the best CNC machines, there can be slight tolerance differences between otherwise identical components. For critical components, like this built-up crankshaft, it can pay to make an additional one or two. You can then chose the very best, the cream of the cream, for the final assembly.
