And, yes, your earlier comments on the forces generated from a heavy metal
prop were constantly in my mind. I plan to go to something lighter soon.
Hopefully a new design variable pitch I've heard is under development
somewhere in internet land!

Butch is still working on it despite personal adversity.
The hub is real heavy but it is very conservatively designed. The blades
are carbon fiber so it might work well on your gearbox. I think it would
be overkill for a slow airplane. Sorry Butch to lose the sale for you :-)

Hey Paul,

Is there anything that I can do to help you in the Prop Project?

I have a 3-axis NC mill (42" Bridgeport with Analam controller) that doesn't have
to much on it now (amazingly, I have finished up most of the current projects that
I started! very rare! ;-) A simple surface grinder and lathe round out the stable.

Later,
Blake

I don't know. Butch, do you need some parts made?

Can you make some of these plates for us Blake?
It would be really really cool if you could pocket these patterns
out of the motor plate. I got the dimensions.
Cosmetically it would look very professional and would add a tremendous 
amount of credibility to rotary engines in airplanes. What we have 
now looks a bit crude and home made. Not to mention the two or three 
pounds of weight savings. I think you could get as much as $300 for 
these things. I'll send you mine so you can use that as a prototype.

Also a two piece end housing like this might be a good project.
