Jerry,

The bridge PP is to stop the very thin and flexible seals from being spit
out the hole - but your also spot on with other stuff like overlap.

I claim rights to the first RX8 PP design, but of course everyone can use
it.

I thought you were going with the beam mount as it's your design?

The biggest cost by far is the machining cost, I wouldn't lumber the builder
to do the machining because it must be precise, but for someone with the
skills, they would save themselves money. I'm working on the machining costs
to get them down

For instance Butch will be doing his own and will be testing the design -
for those that don't knew he's an Aviation engineer and my project partner.
He is currently looking at costings as well and will be handling the US
market, so everyone in the US will be dealing with someone they know and
trust. I'm hoping he will get to all the air shows with what ever other
products we develop as well!
We will get there!
George
