So I've got what I hope to be the center of the star cut out. The dome light fits- OK? I was hoping for a little more of a snug fit. The wood frame for the light isn't as perfect of a circle as I had hoped, but it should work out. I can also sand it to get it looking a little more symmetrical.This thing was seriously a pain in the butt to make. Probably 'wrong tool, wrong job' type of a thing, but it looks like this will work out. Next, I need to cut the 8 triangles that make up the rest of the star.
