Figure 6-10.—Bending tubing with hand-operated tube bender.
Hand Tube Bender
The hand-operated tube bender, shown in
figure 6-10, consists of a handle, radius block, clip,
and a slide bar. The handle and slide bar are used as
levers to provide the mechanical advantage necessary
to bend tubing.
The radius block is marked on
degrees of bend ranging from 0 to 180 degrees. The
slide bar has a mark that is lined up with the zero mark
on the radius block. The tube is inserted in the tube
bender, and after lining up the marks, the slide bar is
moved around until the mark on the slide bar reaches
the desired degree of bend on the radius block. See
figure 6-10 for the six procedural steps in tube
bending with the hand-operated tube bender.
Mechanical Operated Tube Bender
The tube bender, shown in figure 6-11, is issued
as a kit. The kit contains the equipment necessary for
bending tubing from 1/4 inch to 3/4 inch in diameter.
This tube bender is designed for use with aircraft
grade, high-strength, stainless-steel tubing, as well as
all other metal tubing. It is designed to be fastened to
a bench or tripod, and the base is formed to provide a
secure grip in a vise.
