<div>The main Cougar core is cast metal, Marv. Folks have=
complained that the metal used is somewhat soft, since it also=
forms the bearings for the joystick gimbal pivots, and they tend=
to develop minute amounts of "play" over time. =
This leads me to believe that the cast core could break if=
subjected to repetitive force loads of the RW F-16=
variety. Moving the pivot from the center of the housing=
2" lower into the base should result in approximately=
1/2" tp 1" of play, which will translate to about 3 -=
4 times that at a distance of approximately 12 - 15" from=
the pivot (not to mention a reduced force load due to the=
increased lever arm). This movement could be translated to=
a standard joystick gimbal that incorporates the stock Cougar=
pots, something I'd really like to do, given their precision and=
proven interface with the Coug's electronics. Once one=
nips the gimbal pivots off of the Cougar core, it will slide=
into 3/4" gas pipe with room to spare. This forms the=
beginning of a new core that extends the afformentioned 12 -=
15", albeit stepped down at some point to 1/2" gas=
pipe, and mounted in a new gimbal composed of inline skate=
bearings. I want "robust" too, but with a degree=
of play more closely matched to my superspiffy pedals.=

<div>Thanks for the detailed info, and the terrific war=
story. Sounds like the guy should have put out a line for=
some good fishing, if he was that close to scoopin' soup.=
