The basics of bending conduit include removing the cutting burrs from the cut end of conduit, marking the distance where the conduit changes direction, and marking the middle of the conduit bend. Double check these markings, and mark the surface where the conduit will bend. Thread and couple the conduit before bending it. Couple the threaded end, and remove the coupling. Use a high quality pipe or tube bender for the actual act of bending the conduit.
To remove the cutting burrs, use a knife's blade to scrape away the excess. After determining where the conduit bend will be -- usually where it secures within a fitting -- mark the point with a sharpie. Determine where the middle of the conduit bend will be, which is largely dependent on what the angle of the bend will be, and mark this point as well.
Match the bending point of the conduit with the marked surface where the conduit will actually go to confirm the marks and bend angle. To prevent any thread damage, thread about 3/4 inch into the conduit, which you can use with a die later. Add a coupling to this threaded end of the conduit for added protection. Use physical leverage with your foot or another type of pushing pressure in combination with the pipe or tube bender to physically bend the conduit.
