Bob, a few years ago we did a 4 acre light manufacturing building. We ran 3/4 EMT on the side of the purlans and offset down 3" to a 4 sq in the center of each 25' bay. We would mark a whole bundle of 3/4 at 3" and 9" from one end(in pencil so it would rub off when we were done) then see who could bend 10 pieces the fastest with the least amount of "tweaking". It was fun! I tried to keep track of the number of offsets but gave up when we went over 3000' of 3/4. Climate controlled building year round, large 6' x 16' scissor lifts, clean work place. Best job ever! Plus I got to be "automatic" at bending offsets.
