If you think there is 10 lbs to save in Tracy's PSRU, that's huge
considering CG and all...If someone is willing to get the necessary
components that can be whittled and you direct in the ares to be machined, I
would be willing to do this for a very small sum to cover the tooling and
possibly the fixture material, about $200.  NO other machine shop would
touch something like this for under $1000 .................

thanks

I'm interested! My psru still in the crate.

Here is another way Jeff. We rejected this idea a few years ago because of
excessive cost. The cost on NC milling has come way down recently.

The big weight savings is it combines the schertz beam with the adapter
plate. A schertz beam alone weighs up to 9 pounds depending on the length.
Bob White tested it for us in a crash.

The right side can be much shorter to accommodate a rad on the cool side of
the engine. I'll do a suggested dwg for you. It is a half inch thick. Jerry
Hey tested it for deflection and Jarrett did an FEA.

I will have bottom Radiator, and what looks like 25.98 between barry centers
if I read the drawing Paul made of the mount for me correctly.
So combo plate, then some shaving on the housing, what, 19 lbs saved???? 8-D

Not quite that much as some goes and some stays. I would say 15 pounds is possible.
We should standardize on the asymmetric mount as it can be used with a bottom rad
or a right side side rad.

It will look something like this. I'll have to redo that zenair dwg if we use this
plate.
