hello shaneaust. if i'm not mistaken the article is slightly misleading. you must adjust your altitude UNDER all your tracker. see the unit i use . especially the bottom board. it's basically a barndoor with some mods.
if you point the hinge to the pole you should already have your alt set. you are correct. turning the screw will track in ra. image the whole thing sitting on a wedge or tripod with the angle you need already set.
