    So I've been looking for a mill for quite sometime now, but unfortunately they're 1. Rare in Houston, and 2. When found, extremely expensive. I happened across this mill on craigslist and it was priced significantly lower than anything else out there, including clones.

    If the dealer tag is to be believed, it's a 1977 model with factory installed true trace equipment. The table is 9x60, and it has a 2hp variable speed head. More importantly, it has manual feed handles on all screws. The downside to the T-Ram is that it doesn't have provisions for "nodding" the head. I've been told that I won't miss this feature.

    The table and saddle feel pretty tight, with a maximum of 0.020" runout on the X, and 0.015" on the Y. You can still see the scraping on the ways visible.

    The head will need spindle bearings as they were stuck when I got it. I managed to get them free by soaking with Kroil, but they're quite noisy now. I'm sure they're junk. The rest of the head seems okay.

    I managed to get the mill home and set next to, and inline with the C-16 Holbrook. I now need a bigger shop!

    This is my first mill, so I'll be learning from scratch (with no tooling or vice, it didn't come with any)

    It's one heck of a mill. I've already got the head apart and I will need spindle bearings. Everything else seems to be okay so far. I plan on pulling the table and cleaning out the debris, especially around the brass nuts.

    Only bad thing is that I don't own a single piece of r8 tooling or a vice. That'll come after the 350.00 spindle rebuild kit I guess.

    I would search out your bearings on ebay I was able to get mine I think for a total of $165.00 and some change for a set of bearings on my 2hp head. Neat machine you have there! Awesome project!

    I've got acme screws with brass nuts. I've pulled the X and Y screws and have them cleaned and sitting to the side. I can't get the gibs out though, they're well stuck.
