Paul I sent this photo yesterday but it never showed up on the
newsletter.  Today we are making the Barry Mount holders.  The stand
offs hopefully will done in time  to post some photos of the entire
package  before the newsletter shuts down.     Jerry

That is beautiful Jerry. Do the same thing for me.

Weld a thick 6.25 inch diameter flange to a piece of four inch dia.
steel
pipe three feet long. Bolt the steel flange to the center of the plate
with 12... 1/4 inch screws on a 5.875 inch bolt circle. Clamp the
plate
all around to something strong with a vertical orientation. Hang 200
pounds off the other end of the steel pipe and measure the angle of
the
steel pipe before and after with a bubble protractor.

It is too hard to calculate this sort of thing short of a finite
analysis program.

BTW Mr. Any Mouse a machinist bubble protractor will measure down to
about one degree
resolution. Anything less than that is not worth worrying about.

Geeze!!!!Your projects are getting tougher and tougher.    This one
is a
day's labor, cnc machine time plus the materials.  However I am
mounting
a center bolt circle plate on a two inch diameter  post as part of the
engine mount fixture.   Would that be of use?   Jerry

We need the four inch pipe with flange. But no NC tool is required to
drill a bolt
circle. You can flame cut the flange and sand it smooth. No real
precision
is needed with that.

We need to make Tracy less nervous. In the mean time folks, no
Lomchovacs,
flat spins or 180 pitch downs from a vertical penetration until we
measure
the stiffness of the pocketed motor plates. Non pocketed motor plates
are OK
for severe aerobatics.

OK,  I will have it tested by the time you get back from OZ, unless
Blake is going to do it.    PLEASE Blake, make my day.   Jerry
