The center post is indeed the angle changer. There's a 20:1 BAG versa at the base attached to a 1/2" 0.25 lead screw. Yeah, the 1/2" screw is a bit overkill, but we already had it and the nut in the shop.

We're planning on shooting either from the far side or near side of the pyramid. For ranging and alignment we want to just run into the pyramid. A passive hanging system wouldn't have allowed that. If the active system gives us any problems we'll just bolt a passive hanger on.

The simplicity is thanks to designing and building within means. We graduated a lot of experienced seniors and had a lot of new students and mentors this year. Plus a lead mentor with a lot more time constraints due to a new son. So said lead mentor put some limits on what we could practically accomplish in our 6 weeks. As a result we're going to finish with time to spare for practice this year.
