[Land-speed] Multiple Engines

[Skip Higginbotham]

Thanks everybody for the info.
Gary, I have the actual drawings of the Vesco coupler courtesy of 
Rick and Don several years ago and it looks nice and strong and good 
compliance. John, I have discussed the coupler issue with Tom and 
Gene some time ago. Their coupler idea without the fluid damper is 
roughly where I have ended up using Mark Williams coupler materials 
and quite a bit of trial and error in design and build of the coupler 
. I don't think that I can eliminate torsional harmonics with a fluid 
damper so I don't use one.....Nolan and Rick White used a simple chain coupler.
I have found, so far, that compliance must be considered before there 
can be a harmonic issue related to breaking a crankshaft. In other 
words, without enough compliance the engines will kill each other 
before the harmonics get going.

I will see what happens.

Thanks again for all the help.
Skip
