**constant offset** A **constant** separation between a geophysical source and a receiver (see also **OFFSET**). **Constant**–**offset** profiling (COP) is a specialized method of marine seismic profiling using two ships, one shotfiring and the other recording, which travel along a profile at a **constant offset**.

Keeping this in consideration, How do you calculate 22.5 degree offset?

For any fitting angle that is **22.5 degrees**, the true **offset** is multiplied by 2.613 to get the answer for the diagonal. The setback for fitting a pipe equals the true **offset** multiplied by 0.577 for a fitting angle of 60 **degrees**. The true **offset** multiplied by 1.000 equals the setback for a 45-**degree** fitting angle.

**How do you match kicks in conduit?**

Subtract 1/2 the diameter of the **conduit**. In this case, 1/2″ **conduit** is about 3/4″ in diameter, so subtract 3/8″. Now subtract a second amount equal to the distance from the center of the bend to your start mark. Place the start mark of your bender on this new mark on the **conduit**, and make a 10″ **kick**.

**What is the multiplier for 22 degrees?**

**How do you bend a 3 point saddle in 3/4 EMT?**

**What is take up in conduit bending?**

**Take up** is a amount of **conduit** length used to figure out where to place the marks on the **conduit** before the **bend**. Most hand benders have the **take up** stamped on the bender or on a sticker – usually on the bender handle.

**How do you bend a 3 point saddle in 3/4 EMT?**

**The steps to making a three bend saddle are:**
