JKB, those are old Otis controllers from the sixties. That's the cool part...I get to experience the relay logic stuff, and the latest and greatest static units. Many of the older units are scheduled for mod. I'll try and get a shot of a new unit, but have 40 hours of OSHA training next week, and Arc flash, confined space, and respirator after that.
Canyoncreek, I'm building our units from 3/8" plate, rather than castings. I hope they turn out okay, here's what I started with. I'll post a few more photos soon.
