Ohio Survivor, here is the information about the angle of the poles.

You can't really tell from this angle, but I have it slightly angled backwards so that the head end of the pole is farther...

I'm going to be making this stand this weekend, for an upcoming hang.

Instead of a spike at the bottom or a plate, you could just drill two holes in each of the pieces of wood and put two stakes threw those holes. That way it would provide more stability for the poles.
