Chapter 8 / The Z and Y Axes

I needed room betwe en the bottom of the z-shde and th e top of the
y-slide as clearance for the acme screw bolt hol der to be mount-
ed on the underside of th e z- sltde. I util ized the holes alread y pres-
ent in the y-s lide at the bottom for the bearing block needed to
ho ld the acme screw that moves the z- slide up and dow n (see
Figure 8. 10).

screw support bearing.

The bearing block wa s too wide to fit between the 1 X 4 z-sllde
supports, so I trimm ed off about 1/ 2 inch from either side and
modi fied the bo lts I used to hold it dow n (see Fig ure 8. 11 ).
