Do you have a link to your lathe rebuild that Greg mentions above? I just love to see a project go from before and after. I've read every one I can find and am amazed at the quality and craftsmanship and the love that goes into bringing these fine machines back to their former glory.
And of course I'll be watching you resurrect your mill as well.
Chop, chop!

Enjoy!
I bought some primer, more paint (same smoke gray as the lathe) and more rollers today... tried to buy a 5/8-11 eyebolt for picking up the ram but no luck. May have to order one from McMaster-Carr.
Replacement mill head got here today, only a week late. The trucking company did send it out on a lift gate truck though after I was (politely) pissy with them about it on Tuesday (who sends a non-liftgate truck to a residential address). I never realized how much bigger a Vari-speed Bridgeport head is than a step-pulley head... the thing's enormous. Looks to be in decent shape, and has the only air brake I've seen on a BP. I've seen lots of powered drawbars (which this doesn't have being a QC30 spindle), but never a brake. Also has something bolted over the quill scale which looks to be some sort of indicator holder. More investigation will follow.
I made a shiny spot on the bare aluminum upper head... you know what that means.

Did a little work on the track car engine this weekend and also started taking apart the new mill head to go through it today. Major assemblies came apart super easy. Everything looks to be in good though incredibly dirty condition. Also looks like it might have gotten a bit damp on the way here, little bit of flash rust on the drive pulleys but comes right off with a little scotchbrite. Motor spins nicely, all bearings feel good, mostly just needs a ton of cleaning and regreasing. While I'm in I'll probably redo the bushings, bearings, and belts as they're not terribly expensive (and I won't have to take it apart again).

More done on the mill head tonight, took the upper belt housing apart. Very very dirty but didn't find anything I didn't expect. The bushing in the moveable side of the front sheave is paper thin and had a bunch of slop. Bearings don't feel too bad but I'll replace them all. Belts look old but not in bad shape. Thinking about taking the big castings over to the local auto parts machine shop to have them put through the parts washer cabinet, would save me a bunch of time cleaning.

More progress has been made, but also some unfortunate discoveries. What I thought might have been a little dampness getting into it from shipping turns out to have been the supplier pressure washing it. While doing so they filled up the cavity where the feed reverse/feed worm shaft goes, turning everything inside into a ball of rust. I had my first warning of bad stuff when I took off the gear housing from the quill housing and found this:
Nice puddle of water... the head had been lying on its side so corrosion was limited to the side of the casting here. A little wirebrushing and metalprep then paint will fix that.
Continued to disassemble, and everything else on the head was pretty decent... until I got to the aforementioned feed reverse/feed worm shaft area. Where I found this:
You can see the water in the gear teeth here...
The good part is the machine tool company I bought it from are being stand-up guys and making good on it... it's about $300 worth of destroyed pieces. They haven't paid me yet though.
