Eric,
When I put together the prototype of the motor mount, I posted pictures to
both lists, I think. At the time of designing it, I did stress calculations
on different 'beams' to find a combination of dimensions and materials that
would put the bending stresses into an acceptable range. I settled on 0.065
wall rectangular tubing measuring 2" x 1". I wanted to mount the oil cooler
below the motor mount beam for easy access to air.
The further work that Jerry Hey has done, making it a 'hat section' allows
easier fabrication, and he is statically loading the beam to test it, which
I did not.
BTW, I did not name the mount.

I have examined the "Shertz Beam" Motor mount on "the other" Mail List.
Searched and did not find a comment on this list.
Other than it is recomended by "The Other" list, is there anything wrong
with it?
I am looking for solid/semi solid engineering critique. I really dont
want
to talk about "feelings" or "preferance".
Thans for your time.
