REFLECTOR: Fixes for Stick Slop

[Brian Michalk]

There has been little discussion on a fix.  My solution involves making 
a saddle, I'm not sure if it's what the factory does or not.

I think the tubes are 1/2", so I bought some 1/2"ID, .25" wall aluminum 
tube.
With about 2" of stock, I first machined a flat on opposing side, 
leaving about 1/8" thickness.
Next, cut the tube in half along a plane parallel with the two flats.
Take the two halves, and place them flat to flat, drilling a hole for 
the bolt.  The tubes can now be cradled in the saddle.

The flats help support the torque transmitted to the two tubes at right 
angles.  For extra smoothness, use a thin teflon washer(or sheet) 
between the flats.
