Figured out how to cut the face, and did so; Brian mounted the lenses to a mounting-board that'll go inside the head, got a friend to scavenge gaskets for the lenses, and built some segmentata lorica shoulders. He still needs to extend the shoulders down to the wrists, I need to mount the lenses and speaker in the head and then attach the head to the neck, and we need to fabricate the ankles, cover the shoebox-feet with tinfoil, make a harness to support the torso on the wearer's shoulders and install it, and figure out the undergarments and wrists. The hands are just two pairs of channellock-type pliers; the wrists are probably just going to be shop-rags painted silver and wrapped around the pliers.
And that's it, and we're done. I may get some progress pictures from Brian's wife Crystal; if so, I'll see if I can figure out how to post 'em here.
