I decided to use the existing hole because the nut fit. I need 13
inches fro m center to center to allow me to use the bearing hold-
ers on the pla tform I removed from the NuArc copy came ra (see
Figure 7.8).

I removed the guide rai ls for the y-axis from the nuArc copy cam-
era for use in my CNC machine. They were longer than 1needed,
so I cut off the excess with my abrasive cut off saw. The bolt holes
alo ng the length of the rai ls are at 12-inch cent ers so I drilled four
hol es in each of the spanning beams directly down the center of
their length on 12-inch centers (see Figure 7.9) .
