Cleanup work continues. More parts rotated through the degreaser. I replaced the original 3 gallons of cleaner with a 5 gallon bucket of the same stuff now that most parts were cleaned of the bulk of the grime. The column took its first bath the other night and is just about ready to prime and paint. The plan is to prime/paint over any existing paint that survives the cleaner and followup steel wire brush. I'm not motivated enough to work on completely stripping these parts down to bare iron during February!
With the parts starting to get clean, I took stock of which parts could start being derusted and painted to protect them. The saddle, hand cranks, and some other small parts were grease free and ready to be finished, so I set up a small tub of Evap-o-rust in the basement where it is warm to start that process. This stuff seems pretty good, just soak the parts in it for a few hours or overnight and they're just about ready to go. After being removed from the rust remover bath, the parts will be rinsed with water and dried. Then, they'll be final cleaned with Acetone and painted.
The column before and after taking a bath. Quite the improvement. The color on the right is more like the Smoke Gray Rustoleum I plan to repaint with. Might be a little lighter than original, but looks like a pretty typical machine tool color... I hope.
The Z axis miter gears fresh from the cleaner. Some of the teeth were chewed up a little, but overall in pretty good shape.
The spindle mostly cleaned up. The bearing still needs a little more grease to be blasted out of the rollers, but otherwise, it's ready for rust removal.
The saddle, cranks, and some other parts in Evap-o-rust in the basement. Stuff seems to work well, but it isn't cheap.
