I have several views of rather simple SuperWedge mods which illustrate
the SuperWedge altitude knob. A slightly modified Superwedge works
quite easily in both azimuth and altitude. The results are that my four
fully tightened 3/8" bolts in altitude do not prevent changes in both directions.
I use three 3/8" bolts in azimuth which are also kept tight.

With a few simple mods as Gene, Ric, Chris Heapy, myself and others have
described in earlier posts, this wedge is an excellent choice for portable use-
quite stiff.

The illustrations are in the "Mods Gallery" section at the following URL:
