How do I bend elect. conduit?
I have a 5" radius 1/2" emt bender and 100' of 1/2" emt. I need to make three bends in each piece, 1- 90 degree in the middle and 1-45 degree bend on each side of the 90. Here's my problem: I need the "legs" (sides - picture a doghouse with a 90 deg peak and straight up and down sides) to be exactly 27" apart INSIDE measurement. Now, where do I make my marks on the pipe and what direction do I bend (facing the 90 or facing away from the 90)? I need these measurements to be precise so I can make all ten pieces of pipe the same. How 'bout you Journeyman Electricians? Anybody. Any help will be greatly appreciated.
