Dear Rotary People
        I have welded titanium  when I worked for Pan American  world  
airways in N.Y.  it takes alot of preperation to do it right. After welding 
it if the weld has a blue color like chromed exhaust pipes get after running 
it is no good. While at Pan Am we perfected ways of doing it out side of a gas 
filled argon bubble. A lot of your 747 eng hot section have titanium parts that 
 we repaired so i  think a muffler for the rotary eng is possible. Other 
ideas to consider: some of your other alloys in the stainless steel family 
inconel, hasaloy x and w, monel,etc I think every possiblity should be looked
at and considered before using titanium also it is VERY,VERY expensive. But 
if some one wants one after everthing is said and done i would  be interested 
in building it.
