There was a QST article a couple of years ago about using the Alliance Pass
Through rotors as elevation rotors.  The article included making a mount for
it and so forth.  I think it was December 1998 if I am not mistaken.
Anyhow, I followed the plans and it works great.  My rotor setup consists of
a large TV rotor for azimuth and an Alliance "pass thru" for elevation.
It's all manual, it's slow, but it cost me less than $50 to buy it all and
assemble!
