NYKenn,
Thank you for the input. Some areas of this machine will never be pretty, but I hope to get it 100% functional. I may need to purchase a few parts, or have a little machine work done to get there. I think I'll try using some JB Weld as a sort of metal Bondo on a small area and see how it goes.
On arrival, the machine was quite wet with a lightly oily substance. It appeared like someone recently had hosed it down (fully assembled) with WD-40 or something similar. So it has been a disassemble, de-grease, de-rust, and clean up operation so far.
The de-rusting process removed all traces of bluing from the affected parts. I'll try to find a way to re-blue or blacken those parts. Been doing some reading/research on cold bluing & blackening products, but haven't tried any yet.
I'll try to make postings with pics as it moves along.
