Not for nothin', Joe, but checking the gibs is normally a weekly
cleanup/lubrication task.
I normally expect after one (not over-fed) cut in either direction to
pull swarf in the other.

Yep, but I don't think people really do it weekly.
Especially, the table-saddle gib, which is quite inaccessible.

Yes, and the fact that this didn't work is what got me looking.

Joe,
Did you buy it new? If not, did you do a tear down to inspect it?
My Bridgeport needed the oiling system repaired, a bit of shim on the knee gib, and a new
Y screw and split nut to get it up to usefull status. The Y screw failed due to a blocked
oiler.

No, I bought it used. It was made in 1965, and looks it.

No, but I did see and hear it run before buying it.
I have been incrementally repairing things, with periodic reports to RCM
documenting my progress in learning both machining and machine tool repair. The
big problem has been things frozen by lumps of spooge. As time permits, I take
something apart and clean it, lubricate it, then reassemble it.
Having never owned a machine tool before, I would be loath to do this all in one
go, even if I had the time.
I also added an X,Y, Z (quill) DRO, which is a great help.

The Millrite has no oiling system save the user with oilgun in hand. So far,
spooge removal has sufficed, and I have not had to replace anything.

The Millrite is a very good machine for the HSMer.
Simple and easily repaired.
