EMT Bending, Easy-Mode: Learn Offsets first. It will help with the easy 90° in the measuring, and the four point/three point saddles. Beginners Notes List: (Summary at end of list) 1. Don’t Over Complicate bending. 2. Tools: Right sized Bender, tape measure, marking device: pencil (or sharpie, or I like using BLACK DRY ERASE MARKER (just don’t touch the marks until done bending). Also, to remove sharpie, have a used Dry Erase marker, and just scrub the sharpie mark with it, wipe it off with damp towel/rag. 3. Print, memorize, write out, or just use Notes/Photo/Web Page on iPhone of an OFFSET BEND CHART. 4. Practice when you start out, with old cuts of EMT that are being tossed into trash. DON’T EVER FEAR being seen learning something (just do what works for you). 5. Bends and stance. When doing 90° bends, flip bender so head is on flat ground. When doing other bends, try keeping it upright. 6. Learn to line up your EMT by using a template and marking. I made one out of a FOAM TUBE (you can use insulate foam for water pipes, just cut to fit and use the glued side to stick it together to the cut you make to fit it). The FOAM TUBE fits perfectly over an EMT pipe 1/2”. I cut little triangle marks at four points, marking the north, south, east and west side of the pipe. Line up first mark with the scrape line that can be found on EVERY EMT pipe. Use this method if you have a hard time lining up your bends so you don’t dogleg. 7. PRO-LIST: *** DONT re-bend EMT, if you made a mistake, Start new. *** CLEAN off your markings. *** Picture the bend you want/need, and make it perfectly fit. I can’t stress how important this is, instead of just going into bending like it’s your first time and winging it. *** Make your offsets/bends the same unless you can’t. Consistent bends and offsets look so good, no one notices. ONE flaw in bending, and EVERY Electrician can spot it. *** Don’t forget to clip/secure the EMT where and how your codes states (distances from boxes and from other clips). *** No Shortcuts. NEVER short cut. It only holds you back in life, in the long run. Do it right, do it better, do it as if someone’s life depended on it…even bending a stupid EMT pipe. Everything you do, you want to impress on people, that if they were building an army, they would want you on their army. EMT pipe bending: You don’t need to know all the math, in your first year. So let’s just stick with the easy. Summary: You will usually only need; 10° for JBox offset (Multiplier of 6) 30° for Clearance Offsets (Multi of 2) 90° and 45° where needed (45° multi 1.4) Make your marks. First mark where you want your bend to start (2-3” normal start for a JBox offset). Second mark, encircle pipe, using multiplier formula. Head up, unless bending a 90° bend, to read degree line. Bend first mark, first. Slide pipe forward and turn to line up second mark. Make sure no dogleg, and bend. Cut where needed & Ream your ends. Remove your marks. Place pipe in position and attach and clip. Return all your tools and large debris to trash, before starting next project (so you don’t lose tools). Enjoy your success.

sparky, you use 3/8 * 6(multiplyer) for normal box offset without shrink, but you use 2*2(multiplyer)+ 1/2 shrink=4.5" for this box offset? as i learned before, we dont add shrink between two marks but add to the length

The offset was 2 inches so its going to be a 4 inch spread, but for every inch of obstruction height it's a 1/4 inch shrink. 2 inches= 1/2 inch so the spread would be 4 1/2"

@SparkyChannel 3 жыл бұрын

Hi David! Perhaps you don't have room to make 10° offsets. In that case you can choose a greater angle for the bends because when you do the offset bend takes up less room. I agree with your professor that most of the time you will use 10° for box offsets.

@Nick-bh1fy 3 жыл бұрын

Box offsets typically are half an inch, both bends will be pretty close together so 10° simplifies it, but with larger offset measurements you need more bend in both bends and space them further apart plus 30° makes it a lot easier to pull compared to 45°

@MannyAguilarJr 2 жыл бұрын

Let's see if I got it Shrinkage for 10° bend is 1/16" per inch The object height is 3/8" (space between wall and box hole) So shrinkage is 1/16" x 3/8"= 0.0234375( which is less than 1/16" which is why he didn't use the number because it was too small to measure with a tape measure) So he used the between bends formula which at 10° is a factor (multiple) of 6. So 6x3/8"= 2.25 or 2-1/4. So if he added them like the 1st example then the distance between bends would be 2.2734375" but since he didn't use the shrinkage value because it was so low and unmeasurable by a standard tape measure or another way to think of it is he rounded down to 2-1/4".

Why are you adding 1/2 inch to the 4 inches in between bends ? Don’t you just multiply 2 x2 to get a 2 inch offset. In your other video you just multiplied 2x4 to get a 4 inch offset without factoring in the shrink amount in between the bends.

@marcochang5537 7 ай бұрын

2x4 meaning you measured 8 inches between the bends to get a 4inch offset.
