Yeah,,,but you know,,this is the part I always liked, because it is where you find all the little things that need fixing or replacing to make em look and operate in like factory condition,!! Makes you develop a close relationship with "YOUR MACHINE" I expect Thad will do the same,,,., OH,,and Thad, don't you dare finish it before I get there with Shameless and Les,,,I got them BOTH to volunteer for a few weeks of "Help" lol.

I’ve already had Shameless help. All his melted snow/ice helped me make ruts in Jennifer’s yard. Be a miracle if I don’t wind up living with one of you misfits.

Buy a gallon of Machine 'Way' Oil, use fine steel wool with that to clean with followed by Cotton rags that can either burn or throw away. Do not use sand paper or a heavy wire brush for anything more that large area heavy deposits removal. Keep the Ways oiled with that specific oil using either a nylon bristle brush or cotton rags. I get mine thru McMaster Carr, it is NOT cheap

Will order it this weekend. I can use it on my lathe as well. I’ll get fine steel wool this weekend as well. 0000 is what the local lumber yard will carry. Is that what I want?

Just do not get aggressive with it and be fine. Make Long if not full length polishing strokes with the wool. Rinse out or change as loads up otherwise makes rust aggregate.

Check MSC for way oil too. Might be a little cheaper than McMaster-Carr

Was just talking to my youngest son and he is selling a couple of his extra Bridgeport mills . Seems he has 7 of them now and decided he doesn't need them all . So i might get mine working again as he borrowed a few parts from mine to keep the one in his side of shop working . Has one listed on FB Marketplace now for $2300 . I bought mine when I closed the company I was working for - on internal silent bid I got it for $400 , along with several other things from the shop I ran . Best deal was the Miller 304 welder with water cooled TIG which cost me $1.

My usual go-to for cleaning patina off machined surfaces is a scotchbrite pad and some light oil. If it isn't a running surface (ways and such) then I might take a wide blade scraper and take a gentle pass over it (after it's been oiled) to lift off whatever residue has accumulated, then rub out the patina.
For ways, usually the patina and crud exists on the areas where the ways were exposed, as the parked surfaces are well-sealed from atmospheric ingress. If the crud is REALLY thick, I might use same scraper, or a piece of lexan (think windshield ice scraper, sharpened with belt grinder) to separate the crud, then oil the surface with penetrant, and then a few passes of coarse wool followed by another spritz of penetrant, and wipe with a paper towel. Just don't use the Scotchbrite pad on machined ways, as it will leave behind silicon carbide or aluminum oxide abrasive dust.
The biggest challenge of re-awakening any machine, is making certain that the leadscrews won't become fouled and jam. Turn everything by hand many times before putting power drive on, and start slow, if it complains, STOP, back up, and find out why.
You will likely find loose components... like the threaded nut of the table X-Y, it is usually retained by a bolt or two through from the top center of the table. In some mills, tightening it down snug will take slop out of the travel, but in others, a slight misalignment may mean that the assembly binds.
Another thing that CAN happen with machine tools, is sag. Let's say someone shut the machine down with the table parked a bit to the left, and there was an indexing head on the far left... over time, the presence of that weight placing overhanging load on the table will cause the iron casting to distort. It might not be enough to be of consequence in your day-to-day milling, but it may cause the table ways to bind... and if you loosen them to allow it to pass without the bind, you might wind up with some slop. Smaller, lighter, cheaper machines will experience sag worse than heavier, higher quality machines. Machines that are stored in locations where temperature varies greatly will sag more than those in constant temp.

I’ve been using a rag and mineral spirits on all the ways and machined surfaces. It seems to cut all the old way oil which has become more of a thick goo than oil.
The table top tool a little work but much less than I anticipated.
I did hit a couple spots with steel will the rest I got with a plastic scraper and a mix of marble mystery oil and mineral spirits.
Every part seems to work smooth but my next step will be to remove the table and clean under it and all the machine surfaces and screws and re-oil with fresh way oil.
I’ve removed the belts and the spindle spins smooth and free. The quill moves up and down nicely but will also be removed and inspected.
All in all I’m still quite happy with it.
I have a loaner phase converter on the way. It doesn’t have the 3 phase motor to go with it. Finding cheap motors isn’t as easy as it once was.
I may have to forgo that plan and just get a VFD.
If a cheap motor comes along I’ll run it with this setup to test everything.

IF you've disassembled machine tools before, then fine, but if you haven't, I would suggest you just clean it up really good, lubricate it heavily, and then operate it a little bit, determine what's moving well, and what's sloppy, and where, before pulling it apart.
Why? Well, NO machine is 'perfect'. Because of use, it develops a certain amount of wear in certain places, and as it is used, maintainers make adjustments to it to keep it tolerable in the range it's worked most. When you dismantle it, you obliterate all the adjustment that was done not only to compensate for wear and use, you also nix any original factory setup (shimming, gib tension, etc) and place yourself in a position where you're starting over with an unknown of variable circumstance... at least the factory, when new, had known circumstance.
Don't ask me how I learned this...

The ole mill is up and running.
I can figure out how to post a video.
It runs quite smooth.
I’ve seen several of these that the power feed gear box and driveshaft were very noisy. This one is nice and quiet.
A big thank you to Dave Kamp and to Steve on ILL.
Everything seems to run as it should.

Joe I made a couple tracks in the grass with that ole Allis when I was unloading it. I already had to explain it.

Yes it has a Brown & Sharpe 9 taper. H came with a universal Z collet holder but no collets. I’m ordering B& S 9 collets. I can get you a picture of the collet holder when I get home. Too expensive to get the R8 regrind.
