I used the distance from the center of the lower bearing hole to the
underside of the z-slide to find the cen ter of the hole I drilled in the
angle aluminum that holds the acme screw nul. I then drilled the
hole the screw wou ld pass through. and the holes needed to bolt
the nut holder to the angle (see Figure 8 .12).

aluminum. A equals B.

Next I drilled two holes spaced to match the top two holes drilled
through the z- faceplate and slide-bearing sheet metal (see Figure
8. I3).
