If its going into the oven its some kind of composite. Probably a fiberglass body that needs to be heated to have the epoxy cure. I can’t wait to see what the finished product is. Those pieces sure look big and awesome.
Looks like the makings of a triple-jointed arm.
wow…good luck with that…that looks like it’s going to be really heavy or massive
My guess is at arm. Three joints probably. You guys going to fit in the five or six foot?

If you look in the background you can see the making of the other joint of our spare arm. The combined weight of the aircraft flooring for both arms is 8 pounds. 
All three sections of the arm fit within the four foot category.
