Paul,
 I believe that Mr. Geshwinder's company is/was located in Riviera Beach,
Florida. As the treasurer of EAA Chapter 133, I had earlier hoped that I
could entice Mr. G to be a speaker at one of our chapter meetings. I later
heard of his passing. Do you know if his PSRU company is still in business?
If so,
Where?
Who is running it?
How might I contact them?

I belive Mr. Aucklund of Legend was running it for awhile before he
switched over to
a PT6 clone. Bill do you know anything about this?

I think somebody took the project over but I can't recall who it was.

I do know that Jeff (Legend) originally had a Geschwender unit on his
"Chevy" V8 (I'll bet not one single part came from GM).  Other than some
stories about repeated failures by ag users, and the obvious insufficiency
when applied as per the mfgrs design charts, I don't know.

There was some discussion of a "new type" of 'HYVO' type chain a few
months back on this newsletter.  Some correspondents claimed HP/inch
of chain width values which were 5-6 times the values in my (recent)
Engineers Handbook of Machine Design (Shigley) which is reprinting
mfgr's application charts.  Perhaps there is a new design which might
make this style more competitive.  I still lean towards a planetary
box, symmetry is good.

I agree with Paul - Ignore the mfgr's design specs at your own peril.
