Cross Slide started acting up while threading some 7/8-32 tubes.
Decided to tear it down and find out what was up.
All I've got equipment wise to check this is (4) pieces of granite from a CMM that was getting scrapped.
(2) pcs. @ 3" x 6" x 32"lg.
(2) pcs. @ 2" x 4" x 24"lg.
I don't have a proper surface plate yet.
Now if (and that's a big 'IF') I blue'd this correctly, it looks like to me that the top piece is convex and the carriage is concaved.
Also interestingly, the gib is bowed again. I had it straight back in '14.
Ya know, when I bought this hunk I really thought that since it was mfg'd in 1998, in Taiwan, it would be fairly decent. Goes to show you.
This puppy was in a maintenance shop of a granite counter top mfg. A former manager was at the auction and said it saw infrequent use.
I don't see _any_ signs of scraping on the top piece but the carriage does.
Since I don't have any of the tools needed for scraping and since I also do not possess the necessary skills set to perform said function, I'm going to have to come up with a shabby 'shadetree' solution in order to get it to operate somewhat more smoothly.
Third attempt at bluing the top slide.
2nd attempt, I think I had to much on the roller...
Blu'd the carriage with an edge of one of the 24" plates. Rotated it 180° both sides.
Top piece laying on the floor. I don't see any signs that it was ever scraped.
Just for grins I did the bottom of the compound... No scraping on it either.
