I read Fred Moreno's analysis of his door frame, and I concur in many 
respects.

The whole door needs to be stiffened by adding Carbon Fiber on the entire 
inner side, as my last posting mentioned.

We were building kit No. 53, and removed the locking mechanism in favor of 
our own design of sliding pins.  This was prior to the Lancair version of 
sliding pins.

When we filled the interior of the door stiffener with epoxy micro, we 
removed the co inspection plates of the stiffener, Carbon Fibered over them, 
and filled them with epoxy micro.

In the area where our pins went through the stiffener ring, we used epoxy 
flox to fill the ring interior, and then we bored the horizontal holes thru 
the ring to accept our sliding pin mechanism.  We also built up a block of 
epoxy flox behind the door frame to accept the pin in the locked mode. This 
block was also surfaced with carbon fiber extending to the fuselage to give 
it more strength.

>From my personal observation, in actual practice, 20 lbs of door seal 
pressure is too much.  Inflate the seal until it just barely seats and blocks 
out the noise of the engine.  If you get in the air, you can always tweak the 
pressure a bit.

I thought Fred's experiment was very good, and will help future builders 
solve this problem.
