Study the bending project as illustrated in figure 1. 2. Using the illustration in figure 1, determine the required measurements to properly form the bend. 3. Working from the left on the conduit in fig. 2, show your measurements and layout. Use the 3-point saddle bending chart with relation to 45-Degree Center Bend as a guide.Offset bends. Almost a sidewinder pattern, this bend incorporates two 45° angles in order to shift the conduit beside an obstacle but still run in parallel with the old line. Three- and four-point saddle bends. A variant of the offset, where the 45° bend returns back 45° after clearing an obstacle.find the center of bend. usually inner side, two straight edges, else with EMT, it's where the grove of the shoe leaves an imprint. record distance from front of shoe mark to center of bend mark. do this for 22.5 degrees, then repeat for 45 degrees. do your calculations for a saddle. middle center of the saddle gets shifted forward for shrink. • Making a saddle bend will cause the conduit to shorten by a specified amount for every inch of saddle depth, depending on the size of the conduit. ... • Mark the starting point for the second offset and bend the offset. Remember to use the multiplier for the offset angle and account for shrinkage. 2.8.0 Hand Bending 26107-14

Measure length of bend (X). Subtract bender deduct (see Table 1) from length (X) and mark this length from the end of the conduit (Y). Line up (Y) with arrow on bender. Bend until 90° bend is formed. Table 1 Measure and mark distance on the conduit from a fixed point (X), to the back of the 90° bend, point (Y). AlignThe bend test uses a coupon that is bent in three point bending to a specified angle. The outside of the bend is extensively plastically deformed so that any defects in, or embrittlement of, the material will be revealed by the premature failure of the coupon. The bend test may be free formed or guided. The guided bend test is where the coupon ...3 point saddle (emt) measure center point of saddle and mark measure and mark both directions away from center pipe in air, emt bender first mark, closest to end of conduit lay on center mark of bender, bend to 22.5 second mark middlle, lay on star of hand bender and bend to 45 last mark, lay on arrow and bend to 22.5 Your center will always ...The last type of bend described in this manual is the four point saddle. This bend is made up of two equal size offset bends bent in opposite directions. This bend is used to jump over larger blockages than a 3 point saddle can handle. All four marks are placed on the raceway before any bending takes place. Stub up bend Back to Back Bend Offset ...

The 90° bend is made by bending the raceway until it looks like the raceway is bent to 90°. This will get easier with experience. The EMT bender also has several marks that are used to line up various types of bends. These are the arrow, the star and the teardrop. The teardrop (notch or rim mark) is used for the center bend on 3 point saddles.By WonderHowTo. 10/9/08 9:39 AM. This video will walk you through, step by step, on how to make a three-point saddle bend. There are different angles you can use to create a saddle bend; in this example, you'll see a 30-60-30 bend. For more, or to get started making three-point saddle conduit bends for yourself, take a look.Jan 14, 2018 · Figure 4: Good Briefing on 3-Point and 4-Point Saddle Bends. Conduit Bending Formulas There are two formulas that I need to generate: (1) shrinkage, which is the reduction in horizontal length caused by the bend; (2) bend distance, which is the horizontal length of the bend region. …
