Does anybody want to comment?
Are there any questions?

Paul,

 This will be very helpful.  Just one nit:  "Dremal" should be  "Dremel"

Thanks Mark.

I also forgot to mention about assembling the engine with
out e-shaft and rotors and pressure testing the coolant
system to 30 psi to check for leaks. However if this is done
right the large area of JB Weld bonded to the vertical walls
of the water jacket make coolant leaks unlikely.

Anybody else have any comments?

I think it is dead on Paul.  It is without variation the approach I
have come up with,  BTW, an easy way to trim the insert to fit the
housing is with a small angle grinder and grinding wheels made for
aluminum.  This is very fast and easy to control.   Note that the
full diameter  bore goes all the way through the housing.  There is
no step.  So I would start with a larger O.D. tube turned down to 2"
in the portion that is in the housing.  A flange can be left that so
that there is a positive stop when the insert is inserted.        Jerry

I want to avoid machine work where ever possible.
The straight 2 inch tube has worked out well.
Makes this as cheap and simple as possible.

BTW it is rather amazing when you think about this.
We have been thinking about reducing the weight on
the engine by using aluminum end housings. That
would screw up the weight and balance of most airplanes
making them tail heavy. We were thinking down the wrong path :)

The right path is 50 more HP for the same weight engine.
Think of all those RV's an Long EZ out there that could
have 50 more horses with no increase in weight or change
in weight and balance!
