hi paul    by way of intro i am an old dog learning new tricks. been
building aircraft and engines since a kid.  am a&p and pilot since 44.
working on the problem of building a single rotor of 100#.  what do you
think of titanium rotors, should save about 10#with the counterweights.
could the titanium be bonded to aluminum side housings?  how do they bond
the aluminum rotor housings to the steel liner?  i have been told that a
formula 1 race team in europe is building a titanium rotor engine now.  they
would not say who.  read where paul yaw used a 7.5 to 1 rotor in the single
rotor he built, is that oem ? if not how was it modified.? i sure am
enjoying the newsletter and web site.  thanks a bunch   walt williams

I have always wanted to try sheet steel with an aluminum water jacket
for end housings. You could make the aluminum part in an end mill or
CNC mill since it is open on one side. 

The end housings are around 35 pounds each so that could save
40 pounds or so.
