You're welcome. I'm glad it worked for you. Take care.

Perks of going union. Anyone you ask will know the answer.

I’m a 2nd year apprentice and I run into mechanics of 20-30 years that can’t grasp the concept

Thank you. I'm glad you enjoyed it.

I used to teach for the UA and I've been to that apprenticeship competition a couple of times. it was a lot of fun. Good luck and thanks for watching!

T TY

Throw is equal to OD x 1.5 subtract throw and weld gap from total offset

Glad you liked it. Thanks for watching.

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.

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

Thank you. I'm glad you enjoyed it. Have a great day.

Not quite so. But you can stop after calculating for "c" and use that as the travel.

You're welcome. Thanks for watching

15.81' or 15' 9 3/4" square root, not squared

I'm waiting on that same answer

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)

@@RB-xv4si Bud, I said Travel = C/0.3827 I bet you find that equals about the same as Travel = C*2.613 Good job discovering trigonometric identities though ;)

@@RB-xv4si Who said anything about tangent? cosecant is identical to one over sine. It's math.

@@RB-xv4si Are you ok? Do you have dementia? Do we need to call someone? How many ways do I have to say csc(22.5) equals 1/sin(22.5) for a smooth brain to understand? 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.

Wtf are you even trying to say?

​@@RB-xv4siyou ALREADY KNOW.. the examples are ALWAYS cartoons. And you might feel that "it's the same". But try a rolling offset that's VERTICAL In some cramped space..it's "the same" right? But that becomes a different beast in an actual boiler room or something.. or if you really don't have a nice wall to mark from..because the crap is hanging in mid air in a giant building. And no, your tape measure is NOT going to reach a surface in those scenarios..

@@mebrn5337 that’s a great observation; doing the math right doesn’t matter if you don’t have the right measurement to begin with. 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. It also sometimes helps to realize that this job isn’t for everyone.

@@RB-xv4si apparently, you work in a place where people will let you take all that time to get the laser or getting a plumb bob. Most bosses would yell at you, that youre taking too long.

@@mebrn5337 sounds like a personal problem.

Hi Jose: Sometimes that is the case but in this situation its not. Take care and thanks for watching.

You bet. You can check out my video on fitting allowance to help with that. Thanks for watching.

Skip weld gap, always end up short. Just the fittings. If anything, allow for half the gap, just 1 fitting. Pipefitter trick!
