So it's your fault it has that horrible name? :)
The idea seems a little different, so I wanted a bunch of eyes to take a
look. My buddy tells me the same idea is used on his contentinal.
I have posted pictures of the mount at www.canardaviation.com/forum
A direct link to the post tinyurl.com/2ms2d
Some folks there had some questions, and some seemed a little critical.
They are a frendly sort, but I think they need an explination. Feel free to
respond to their questions, if you wish.
I only have pictures of the beam itself, although Paul posted a pic with a
rear mount show.
Do you have any pictures of the "third mount".
Do you see any weekness in the mount, compared to a bed mount?
Can you explain how it will handel gyroscopic loads?
Do you see any reasong not to put it in a canard pusher?
Do you have your origional pictures I could post there?
I have talked to Jerry and I am looking forward to getting his production
mount.
Driving ahis truck onto his mount does it for me.

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.
