Drill jig made from a standard U-section
• The drill jig shown in Figure 5-18 was built from
standard structural form materials. It consists of
two pieces of angle iron welded to a channel iron to
form a V-section. A larger angle iron was welded
over the V-section to serve as a bushing plate and
clamping mount. The addition of a standard
thumbscrew, drill bushing, and section of rod
completed the assembly.
