The e-shaft in the picture is a modified 13b part. I am currently awaiting a
quote to have them manufactured from 4340 on a 4 axis CNC machine. Once that
is done, I still have the issue of providing the correct counterweights,
finish grinding and hardening the journals. It won't be a cheap part in
batches of 10, but it maybe doable. I'll keep the group posted. Making a one
rotor from a twin rotor shaft certainly isn't the way to go at it
efficiently.
