How do you figure out the rolling offset of a fitting? Got a 90 degree fitting, that I'm rolling on a 45 that I need the offset for.

Then after you get the 22.36 you would then have to remove the measurement of the 2 45s correct? To get the actual piece of pipe. I’m teaching some of my apprentices here and I’m brushing up on my formulas.

Hi Caesar: Yes, that is correct. You would have to subtract the fitting allowance for each of the two 45's. Thanks for watching.

So the offset is the horizontal distance and the rise is the vertical distance?
@electricianed10762 жыл бұрын
What if you have an inside corner where you would typically use a 90, but there's a complication in the corner. There's a vertical pipe, 6" in diameter, and you also have to rise 6" on the adjacent wall to get above a locker shelf--all in just two bends? This is a real problem I've puzzled over. I can sometimes do it by the eyeball method but it doesn't come out quite the way I hope because I don't swivel the pipe for the second bend quite right.
@tradestutor11912 жыл бұрын
Wow. That sounds like a bit of a tricky situation. In all fairness I'd have to see what is going on in the room to even have a chance to figure it out. Thanks for watching.

@@tradestutor1191 , Thanks for the reply. I admit, my description here was slightly hypothetical, but it tried to get at the problem I'm describing. In other words, the numbers do not matter too much; use any dimensions for the rise of the shelf and the diameter of the cylinder that are convenient. What I'm looking for is a solution to a shape very similar to the one you used, except the end of the pipe at the bottom left would be coming out of the page/screen along the corner of the wall and floor toward you. So, it's a rolling 45-45, I think. Since it is rolling (climbing), the hypotenuse grows. Looking from the top down, it would look just like a 45-45. But when trying to bend it, what is the degree I need to swivel the conduit in the bender out of the regular plane of the legs of the first bend to get it to come out right? Is it 45-degrees? I came up with this problem when trying to bend this shape to fit along the center-lines of two I-beams at 90-degrees to one another where the end of one is resting on the other at their corner. The lips prevented me from doing a kicked 90. Thanks again for answering. I really like how you simplified the math using two triangles.

It's the same up to the point that he uses "C*1.1414" Yours would be: Travel = C/cos(67.5) or C/sin(22.5) both equal C/0.3827 Making the travel in this example 41.31 instead of 22.36 The bottom angle of your green triangle would be 22.5 and the top angle is 67.5 (90-22.5)

Most scientific calculators don't even have a [sec], [csc], or [cot] function, because trig identities are so commonly known. This conversation has been like me saying "turn 90° right" and then you saying, a year later, "nah, that's wrong, it's 270° left." I would assume you're a troll, but it's not like you're getting a lot of attention semantically arguing about trigonometry. Hope you get the help you need.

The green triangle is entirely unnecessary. Once you have the blue triangle’s hypotenuse figured out, you just multiply that by the cosecant of the bend angle to get the distance between bends. That’s it

And part of being a good electrician is figuring out how to get the right measurement. Sometimes that involves using a line laser or a plumb bob.
