Russ;
I thought about that possibility but it seems like it (the Rodek block)
would have more vibration-induced stresses when it was a running engine than
they could ever generate with a shake table. I wonder if they have any data
showing its benefit?

Rodek may be getting better blocks from the shake table, but (like you) I
doubt that this is due to "stress relieving". What they may be doing is a
little overall STRENGTHENING (improvemnt to tensile, compressive, and/or
shear strength-- depending on the direction of the displacements), due to
some strain-hardening of the blocks.

Doug;
I suspect they were only shaking any remaining casting sand out of the
block. Rodek should know what they're doing... but I'm still skeptical.

The Rodeck factory is just north of big ditch. We have had our gold
coast
racers club meetings there on several occasions. They give us the grand tour
after our meeting. They have two large tables that they put all their blocks
on
and vibrate for about 30 minutes each if I remember right. They can bolt
about 4
blocks at a time to the table. They said it was well worth the expense and
time
to relieve the blocks. So I have to believe there is something to it. I
don't
think John would have spent the money for the machines if it was not proven.
Ask
me some day how John came up with the name TFX for his new motor.
