Paul,

I'll need some drawings to get a handle on this problem.
What is the stack made up of?  I assume ~2" cast iron
rotor housings X 2 + ~2 1/2" alum end housings X 3.
Need actual thickness dimensions and bolt dwgs or
actual bolts.   We should start out just doing the basic
calculation work and see what that tells us, then consider
whether to do the actual tests with chunks of actual
housings.

Hard dirty work traveling to Frankfurt, but I guess
somebody has to do it.  Take some pix.

You will have to wait until I get back for all the actual
dimensions Bill as the parts are up at the hangar. The al
13B rotor housings are 80 mm wide however and the bolts are 
roughly 12 mm with the necked down diameter to be I would 
guess about 9 to 10 mm. Front fe housing is roughly 2.4 inches. 
Center fe housing is roughly two inchs and back fe housing is 
roughly 1.6 inches. The grip length of the tension bolts 
is about 10 inches long. The bolt spacing averages
2 to 1.75 inch center to center in the combustion
and expansion areas of the housings. There are 16 
bolt holes total in the 13B rotor housing I have 
here.
