PVC frame for GH10

I have been tinkering with ideas for how to best design the frame that will hold the elements and colinear reflector rods. This is what I'm thinking so far. I'm thinking of 3/4" CPVC for rigidity. The reflector rods will be drilled through the taller frame. I might consider 1/2" PVC for the upper frame that holds the elements.

Btw, I went back to Metal Supermarkets yesterday and picked up a short piece of 1/4" aluminum to complete the reflector rods.
