The Gantry

Tools and materials you will require to build the gantry portion of
the CNC machine are as follows:

• Two 2 X 4 steel spanning beams
• Two 2 X 6 steel uprights

• Two 3.5 X 3.5 gantry feet

• Drill press
• Abrasive cutoff saw

• Welder
The ga ntr y moves the length of the x-ax is and carries the y- and
z-axes . It consists of two feet on which the bea ring holders are
mounted. and two upright posts that have the rail holders for the
