The time has come to publish my PSRU work.  This is an original design

with

features borrowed from others, and what has been discussed the last

couple

of years on this list.   The design goals were reliability, cost and

ease of

maintenance.  The design originated from Paul's tubular shaft design
published on the ACRE web page.  Major changes from this design were the
addition of a rear input shaft bearing, use of all taper roller

bearings,

and the QD bushings instead of shrink fits

Nice work Steve.  Anyone with a CAD program (or a pencil) can design a
redrive and it might even be a good one.  The real work is comming up with a
good one that is practical to manufacture.  Haven't studied your design
extensively but on first pass it looks like a masterful job of  'real world
engineering'.  Just the right combination of original thinking and stealing
the best ideas (and I mean that as a complement :)
