Well, after 2 trips to town because the first one made a hit, but the one he handed me & said Merry Christmas turned out to be the only 1/4-28 in a $30 box of supposedly all metric fittings. Then I spied another nominally 10 pack that looked promising so I bought that one. Brought it home, dismounted the nut long enough to get swinging room to install a 90 degree out of that kit, then spent an hour re-arranging the place looking for my mini grease gun before I remembered I had binned it last summer for excessive leakage, so back to town again for a grease gun. Got that, a better one that holds the pressure off the grease with a friction latch, so maybe this one won't always be empty when I reach for it. Greased it up, draped a paper towel over the screw and homed it to my gage, checked & saw the x was off about .3", fixed that in the .ini file, restarted, rehomed and fired off a routine that does the first 3 cuts for a BP #209 nipple. About 4 to 9 thou undersized, but before I try to get that any closer, I need to reset the routine to do a final 2 or 3 passes at each exact size, at which point I can fine tune the home offset to remove the last of that error. My GMC didn't get to cool off from about 11AM-ish till around 16:30. I had to remove some of the 3.2 thou backlash comp as the homing didn't work, throwing errors because the backlash move was opening contact. In the process of this conversion I found a lot more of my 'rubber toolpost' syndrome, so I believe I can make 2 to 4x heavier cuts than before. The left front carriage adjuster is all the way out, and that bolt well snugged up, the left front corner of the carriage was lifting, and I found the rear end was also bouncing some, so some takeup was done there too. So its still a sows ear, but a cleaner shaved version now. :) Thanks for the help on the grease fitting Guy's, it helped to clarify what I really needed to do.
