The work on my CNC conversion continues. After getting the Z-axis moving, I went to look at how to get the oil fittings hooked up and found to my horror that I had installed the ballnut pointing the wrong way. There's a hole in the top of the Z-column that allows feeding in the oil tube, and it was on the opposite side from the fitting. That meant zero chance of getting a tube onto the fitting through the hole, or doing it without taking the column apart. After some agonizing over that, I took the motor and mount back off, then pulled the ballscrew and nut, finally putting the oil fitting into the place it goes. That was a step backward. It doesn't fit.
I'm still researching ways to get around that. I really want to minimize the amount of doing everything several times that I'm trapped in, and I'm especially concerned about anything that would make me pull the ballnut off its screw and involve a potential second Ballnut Removal Tool fiasco. So while I think about this problem, I moved on to build the oil distribution system for the XY table, so that I can put that back together. This required some tubing adapters and some 1/4" OD tubing. I had to order the adapters, but the tubing itself was available in town. It took a couple of days to get everything here and then minutes to finish the distribution system.
In this view, the upper right is a Tee connector. The hose from the oil pump will go into another Tee before this one: one of its outputs will go to the Tee visible here while the other output will go up the Z column to oil that and to another Tee up there.
With some luck, I should be able to get the X-axis motor mounted tomorrow and then see if I can get this whole thing to move under CNC control. It should.
