4.
Place pipe in bender, aligning first bend mark with arrow on
bending shoe. Proceed to bend, reading desired angle on
optic angle gauge.
5.
Rotate pipe 180° and align second bend mark with arrow on
bending shoe. Proceed to make second bend, reading angle
on optic angle gauge.

8.0 90° SWEEP BEND (2 1/2" thru 4" only)
Example: To make a 90° Sweep Bend in 3" pipe
having a 271/4 radius, mark pipe as shown using
information A, B, C and S in 3" pipe chart 7.
See Chart 1.

Figure 8, 90° Sweep Bend
8.1 Operating Sweep Shoes in One-shot Bend
1.
Mark desired stub-up (H) dimension on straight length of pipe
(see Figure 8).
2.
Locate the size of pipe you are bending in Chart 6. Select the
desired sweep radius to find set-back (S) dimension.
3.
Measure back dimension (deduct (S) and mark pipe).
4.
Mark off given number of bites (column A) at spacing intervals
given in column B.
5.
Place pivot shoes in pipe hole size shown on frame. Make
first bend to degree of angle shown in Column C.
NOTE: It may be advisable to overbend the first bite
slightly to compensate for accumulated springback.
6.
Make all succeeding bends by moving the pivot shoe (without
the optic angle gauge) to a hole that keeps pipe parallel to
edge of bending frame while using the same angle of bend.
For 15° and 30° Kicks and Offsets using a sweep bender, see
Charts 3, 4, and 5.
