[NLRS] Elevation rotators for small stuff

[Ray Johnson]

Good point Paul !!

When I am doing  sun noise experiments on the larger dishes (3-6 foot), 
I use a homebrewed Dobsonian Telescope mount that I built for a lousy 4 
" reflector scope.

The Dobson design was created by the Sidewalk Astronomers in San 
Francisco as a cheap way to get decent stability using readily available 
materials and was originally patterened after military gun mounts..

I especially like the part where you take an old Gilmer belt, flip it 
inside out and then tack it to the base to create a huge, cheap drive 
gear. Works Great !!
