Thanks everybody.
In for a penny, etc.. I decided to go ahead and throw in a paint job. Cleaned up the oil ways and cleaned up the old crud. Paint on the sunny side is so-so. chips easily and there's always a bit of dirt under it. Not the best prep. Slightly better than a tractor. I'll leave the wear worry for now and concentrate on the rehab. Appreciate the SB instruction book link.
Apron progress so far. Thought I'd have more time to undertake the project with the work stoppage but I'm managing to stay busy in the shop so I'tll be catch as catch can.
Using lacquer thinner, wire wheels, Die grind sander disks. Don't have any chemical stripper so it will be softening with the thinner and elbow grease for now.
Half nuts were fairly worn so they were sent out for rebuild while the apron work gets done.
Again, the help here is appreciated.
