Hi again Jeff
"it had those little ball/valve oil port thingys"
"Then you pulled them out and tapped the holes with a pipe tap, or did you glue the fittings in place?"
That is ecactly what happened. I left the "little ball thingys" on the X & Y axis screws and all the hiddens ones I replaced with pipe fittings. I screwed them in where I could and pressed then in if there wasn't room for the thread (no glue). They've all stayed in well.
By the way, I used a tap to remove the "little ball thingys". It was the only way I could figure out to get a handle on them.
