Good news today. The head of maintenance at work has connections with someone who can weld cast iron. I sent off the broken pieces of Stripes, and should get them back close to new.
I finished up stripping the last few bits of crud from the other parts of the press, and gave it a bath in mineral spirits, then in acetone. Next was a fresh coat of gloss back tractor paint. Looks like a new press. I'll probably give it two coats, then razor off all of the machined areas before reassembly. It sure feels good to see it start to come together.
