Hi Paul

Some little time ago there was a reference on the list to the Latham

axial supercharger.

I ran across this 1960's material in my old files ( I,m a pack rat ,

never throw anything away ).

I almost bought one of these for a 16&1/2 ft.ski boat I was building

with a 283 cube vette engine.

Although the prices listed on the enclosed old list sound very cheap

today in the 60's it was a

lot of money so I never did buy one.Now I wish I had.
Post this if you think anyone might be interested.
I will send the rest in another  e mail  .Hope I dont overload the

system.

All the best

Grant sent a lot of pages but unfortunately too much to publish.
Here is a good overview. Would make half of a great little jet engine.

Boy! I remember that ad from way back in time. I strongly suspect that it
did not last because it did not work that well. Not to say that a properly
designed axial flow supercharger won't work - you probably just
could not afford it. Vance

Their is a discussion about it on the RX8 forum.  It seems someone named
Richard Paul has the rights to it and will manufacturing it again.  Why in
the heck he would have to manufacture it out of a solid billet I can't
understand.  It looks the original was press punched rolled up and seam
welded.  Of course it only looks that way.

New axial claiming 85% efficiency.

If I were doing it I would invest in high pressure injection molds.
Carbon filled thermo plastic for the stators and aluminum
for the rotors. Also different blade lengths for different stages.
Normally something like this would be locked into the mold.
The trick is to unscrew them from the molds.

The stator parts would be progressively pressed into an aluminum tube while
the rotors would simultaneously be pressed on to the input shaft 
during final assemble.

Also the input end needs streamlining with a gradual 90 degree 
bend instead of the current right angle.

All patent rights expired 75 years ago :)
