[SEL] Blackstone progress

[Jim and Diane]

The dual diagonal keys have a much higher shear strength and were many times 
used in situations that were bidirectional.  Probably an overkill for a 
small engine but nevertheless a first class, and quite expensive, way of 
doing the job.

Hi Jerry.
I don't know much about Blackstone engines, maybe someone can tell us why
they cut the key ways the way they did.
