Accurate Stubs
Subract take-up from desired stub height.
This gives distance at which to place B on bender from
the end of the tube. To make 11", 90° bend with
1/2" tube, allow for 5" for take-up as shown
on diagram.
With 3/4" tube, allow 6"
With 1" tube, allow 8"
True Offsets
Line up arrow on either side of hook with guideline and make 45° bend in tube. Reverse tube in bender and adjust so that X is lined up with inch-mark on bender corresponding to depth of offset desired. Line up guide-line with opposite arrow and make second 45° bend. A true offset, in the sname plane, will result between X and Y.
Back-to-Back Bends
Make stub bend at X with guide-line centered on either arrow located on side of hook. Measure distances from X to Y on tube.
Reverse bender and put A on bender at Y on tube. Line up guide-line with opposite arrow than used when making first stub and make second bend.
Saddle Bends
C -- Center of finished Saddle Bend
X -- Double of the diameter of round object from C
Y -- Double of the diameter of round object from C
Saddle Bend, Step 1
Place tube in bender so that "C" on tube is at notch on bender and make a 45 bend. (A 45 bend is reached when bender handle is at a right angle to the tube.)
Saddle Bend, Step 2
Reverse tube in bender and place B on bender at X on tube. Make return bend of 22 1/2 . Duplicate procedure placing B on bender at Y on tube and complete saddle by making another 22 1/2 bend.
Finished bend neatly saddles round object
Proper alignment of the guide-line with arrows on bender hook will result in the saddle being in a straight line.
To Straighten
Place handle of bender over stub or piece of pipe that will fit inside and push down to the floor in one full sweep.
