I welded th e uprights to the feet only on the sides a nd front where
they met the feet. I didn 't weld the back, so I could rest the bot-
tom-spanning beam on the foot without any interference (see
Figure 7. 11).

feet.

After welding the feet to the uprights , move on to the next section
of this chapter and set up the rai ls on th e frame.

The X-axis: Installing the Gantry

Bearing Guide Rail

Tools and mater ial required to instal l the gantry bearing guide ra il
are as follows:

• Guide rails (Figure 7. 12)
• Screwdriver

• Wrench
• Nuts washers and bolts

The holes for the guide rail support bolts were drilled during the
frame construction process. To be able to insta ll the rail, you must
raise the frame to allow an approac h to the access ho les drilled in
the bottom of the rail support beams. I boosted the frame up wit h
a coup le of pails I had lying a rou nd in my work shed (see Fig ure
7.13).
