Benfield Conduit Bending Manual by Jack Benfield

By Jack Benfield

The enterprise of bending conduit isn't really so advanced because it looks at the start making bends that healthy correct the 1st time is straightforward if one follows a number of easy ideas. because the writer promised, no longer a unmarried technical notice has seemed during this guide -no excessive math... no “trig”...no sines...no co-sines...no algebra or geometry used to be had to study the easy paintings of constructing conduit bends that healthy!

Exactly the same techniques can be employed while using a hickey, except Table F must be used for the take-up. Bending with Hickeys Variable Radius Bends 31 Questions & Answers Q Can hickeys be used to shift conduit stubs on concrete slab work in the case of a missed partition?

Stub-ups in narrow partitions: Bend a 45° or 60° kick in the conduit a few inches away from the partition. This allows the run to enter the partition obliquely. Thus a conduit bend of conventional NE Code radius will enter into an unbelievably narrow partition with room to spare. b. Bending both legs of an offset on the floor: Make the second bend on a slightly raised platform (a 2” x 4” will usually do) or bend at the edge of a loading dock, stairwell, etc. This allows the first bend to hang down in free air.

Bending tools that have been engineered to bend rigid or IMC make NE Code radius bends. ) BEND RIGID CONDUIT AND IMC ON THE FLOOR. If you are right handed apply pressure to the foot pedal with your LEFT FOOT. You will get better footing and feel more secure to have your RIGHT FOOT placed firmly on the conduit and floor. ” Bend with a fairly wide stance. The feet should be 28” to 30” apart. This provides better body balance and more power. pin the conduit tight to the floor with STIFF LEG FOOT PRESSURE throughout the entire bend.
