well. it works. I used a piece of 3/16 steel flat bar (3") and extended back about 10" from the hh mount at the top of the pole. Bent the bar down to the point the
actuator pushed straight into the dish, and the mount had free swing E/W. And then I used a piece of stamped angle to attach the front of the actuator to the mounting ring of the dish- about 12" out from the center- but a really beefy point of the dish. That's the strongest point of the whole dish.
And it moves.
I found out quickly what happens when you go past the balance point- the dish flopped, it pulled the whole actuator up through the lower mounting bracket (around the tube) and bent up the sheetmetal angle.
I reset the tube to 1/2 way out, loosened the clamp, and pushed the whole thing to south again, and really tightened the the clamp this time.
I can go from AMC6 (NASA) to g10r without any drama. But I made sure the limits are set now.
And it sure is non-linear-
count of 400 is all the way east, 500 is due south, 900 is all the way west.
I am used to the HH mount- it will be missed.
Overall I'm pleased.
Thanks for all the help, everyone.
