New cross feed nut, gib adjustment
#4
Well Good stuff OK  problem solved and the best part is no shim needed to get her to  work  smooth with now the full swing . Glad i tossed this around  . Unsatisfied with shimming for adjustment Last night I decided to take  back apart and get to bottom of it all.  Btw i was worried because prior to installing the new cross feed nut i did take out some of the scaring .

Here is what i did in order check for smoothness squareness and full range of motion with a properly adjusted gib. Blue tells the story ..

First thing set out to blue up all surfaces and inspect every avenue .. little by little i had isolated the two rough spots  (where the was original the scaring was) One on RH side of dove tail / gib ( Gib side . ) The other was on opposite side towards front of cross slide. I found both these minor errors by bluing /using the gib to slide with my finger tips listening to feel any resistance . Than I put all back ran friction tests ( by hand no cross feed nut) which resulted in stoning 2 areas on the gib that left the most impression . Next after truing up these surfaces , put back together, felt /examined the bluing on all mating surfaces . ( again without the new cross feed nut ).

At this point I was very impressed everything felt great ,was able to adjust the Gib and get full range of motion with same resistance at full travel. Yea !!! than last but not least found the culprit as to why I could not cross the center line without resistance. Now this time I was confident it was not a drag issue due to the mating surfaces .This one happened to be a high spot inside the cavity where the cross feed nut sightly rubbed. When testing the cross feed nut by itself it was not an issue . However fully assembled it was enough to graze the surface . At that point I took material off the radius on the bottom of the new nut and bada bing end of story. All problems fixed , smooth, cross feed , new cross feed nut with a properly adjusted gib . . Blue told the story but not the whole story..lol... Hey thanks for listing and let me talk it out its been therapeutic .One happy camper again.
