I decided to skip the shoulder construction and work on the head. The reason for this is that that the shoulder has an odd shape to it. I figured that if I could construct the head and dome, I could then jury-rig the shoulder into place.
I cut out the circular pieces and used square dowel rods for the supports. I nailed the rods into the bottom circle and then glued on the top two circles. Overall, I’m happy with it.
Unfortunately, the dome will be a challenge. I can’t seem to find a cheap and easy solution. I did get hold of a large Halloween candy bowl, but it’s too small. I need something light and easy to cut in order to put in the lights/gun.
