Alright, I'm fiiiiinally starting on the finishing touches to my big coop. I'm not even going to say how long it took us to get here, it's plain embarrassing! So I've built the box for the cupola. It fits great! But now I'm trying to figure out how to build the dang pyramid roof and I am baffled... Feeling like I bit off more than I can chew with this one! I've looked at a bunch of woodworking sites and I couldn't make heads or tails of the math. Is there any kind of trick that I can employ to get this thing built? Keep in mind that I am terrible at math! Thanks!
