Sorry I didn't make my 70's welding ref clear. I was just pointing out that mig/tig was not readily available then & that stick welding (aka MMA) would not have been delicate enough (as you pointed out) but gas welding was a mainstay for this gauge of material. I didn't mean that I thought this joint is a weld.
It's Not welded it's Brased (aka 'brazed'). Brass soldered, melted brass not lead. You need oxy-acetylene, oxy-propane or oxy-MAP gas equipment to be able to get enough heat to melt the brasing rod (red heat). Flux (& goggles) is also needed.
Oxy-Acetylene is what I was referring to when I said that the deformation could've come from heating the flash for "welding" that washer to it.
I've taken time off from working in movies to take welding courses, and the first thing we learned was OAW (Oxy-Acetylene Welding). So that's what I pictured in my head, someone with a welding torch, perhaps not knowing the flash is plated brass, using too much heat to try to weld that washer in place.
Y'all know how I feel about Roger Christian. Totally untrustworthy. I don't think I could believe anything that comes out of his mouth regarding these props, not anymore.
I just learned that production designer Roger Christian is the same Roger Christian who directed Battlefield Earth.I don’t believe a single thing Christian says anymore.
"I'm beloved for my contributions to Star Wars and Alien. I'll make it big as a science fiction film director!"Wouldn't we all keep that sorta thing quiet?
