No not really.
I felt something strange when I moved the cross slide so I took it off for adjustments and cleaning.
The strange was an ever so subtle tight spot in the travel back and forth.
The long skinny thing you see in the2nd picture is the gib, it is tapered.
It is used to adjust the slop in the dove tails.
The brass nut thing on the threaded rod is also an adjustment for backlash.
Once everything was cleaned up and put back together the strange spot disappeared.
Took all of about fifteen minutes.
I keep my backlash around .007 no premature wear from being over tight and it never gets worse.
The other picture is the other half of the cross slide upside down.
The copper thing sticking up is what I replaced the carriage lock down screw with.
I got tired of looking for the wrench to fit the other one so now I can stick just about anything in the hole to turn it.
It was made from an electrical grounding rod.
Copper on the outside and steel in the middle.
