If your dish is going to be fixed the only angle that matters is the face of the dish and of course the azimuth.
You are correct, declination is only a factor when you are moving the dish and attempting to track the arc.
You don't even need a plumb pole for a fixed dish.
OK. Thanks a lot. It's really hot today and I'm working slow but I might be able to try some aiming later today. I have to try to fix one little area of damage to the mesh then mount the 4 sections to the ring and attach the 4 arms for the scalar ring, etc.
