Be patient and keep practicing. Bending conduit is an art and can take some time to do correctly. Don’t get frustrated if it doesn’t come out the way you want it to, just be patient and keep practicing. In time, your skills will improve.
From measuring to marking to cutting, conduit bending is truly one of the fundamental tasks for an electrician. Conduit bending is truly one of the fundamental tasks of the electrical construction industry.
If you need to use an airbend to twist your conduit, here's how: Put the hilt of the bender on the ground. Secure it in place with both feet or another reliable anchor. Keep the bender straight and let your body apply the pressure to the conduit. Don't try to use the bender to airbend.
Let's look at the following step-by-step approach. Step 1: Remove cutting burrs from the cut conduit end. Before you begin your bend, use a conduit reamer to remove any cutting burrs left after you've made your cut. Some electricians use a knife to swipe the edge of the cut.

Answer: There is no real formula, but it can be calculated with a fair degree of precision. Multiply the radius of the bend you want to make by 6.28, then by degrees, bend and divide by 360. Divide once more by two, measure from the center of the pipe that far then set that mark at the front edge of the bending shoe.
iBend ensures accurate conduit bends by calculating the math for you, saving you time. You can even customize the app to mimic the exact bender you are using. The app is available for iPhones for $4.99 as well as Android phones for $2.99.
We don't do a lot of conduit work in my area, pretty much short little pieces here and there, otherwise an electrician will be hired to do big stuff. So I wouldn't say it's the toughest task I do, because we just don't do it enough. But if I had to do it regularly, yeah, I would say it's tough.
Conduit bending is truly one of the fundamental tasks of the electrical construction industry. Whether EMT, galvanized rigid steel conduit, or intermediate conduit, you will need to bend it. Bends will be required as part of your installation. Of course, factory-made elbows are available for feeder sizes (11/4-in.
The formula for calculating the bent section of the hose length around a radius is derived from the basic formula that the circumference of a circle = 2πR, where R = the radius of the circle, and π = a constant, = 3.142.
The formula (See Bending Formulas) is: Bend Allowance = Angle * (π / 180) * (Radius + K-factor * Thickness). So the flat pattern length is 1.625” + 2.625” + 0.475" which is equal to 4.725".
R is radius of the pipe bend, Z is the angle of the bend. Setback = radius X tangent ½ angle of bend. Circumference = 3.1416 X diameter.
