- Come with Josh as he draws out an explains a rolling off set I recorded this for a reference to look back on and remind ourselves on how to do one.

Part two please.
This is a good tutorial. You can also use Pythagorean Theorem. A^2 + B^2=c^2
14&1/4^2 + 8&1/16^2 =203.6+65= 268.06. The Square root of 268.06 is 16.37=1’4&3/8” x 1.414 =1’11&1/8”
FYI it’s easier if you draw your rolling offset inside of a 3D rectangle box, instead of a 3D square box
Greetings from South Texas! Love your channel,very nice!,like everything about rolling offsets!
Your buddy is sharp! Thanks!!
W.V Graves was a pipefitter instructor here at Lee College in Baytown, TX where I went to school for welding.
Well, for having done very little pipe fitting and working with tubing, I managed to bumble f$#& around and got the rise, roll and angle of the rolling offset correctly written down but then completely s%$# the bed to finish the rest of the information. Thank you for the explanation because my blue book was apparently a foreign language to me. Working with pre-bent tubing for coolant lines, air lines / turbos on CAT, Cummins, International engines.
ChronicPain so did the video help? Lol
@@JacobSchofield Yes it helped. Currently going over previous information from Friday and trying to recalculate things so I can comprehend what is going on. I know the difference between Pipe and Tubing but the application should be the same. My blue book does not have same info as your blue book. Trying to study up on short radius and long radius tubing for application on engines and such. Do not have my blue book with me at the moment and still trying to figure out where 1.414 comes from. Also working with arbitrary angles as Trucks are not exactly level, engines are not level, Radiators and turbos are not level.
It would also help if I had a fixed point of reference to work off of. Something I could turn or rotate. Gee, kinda like a rotary table that I have in storage and not at work.
@@Delta9D9 1.414 is for 45 degree offset.
I want yo know the distance to the 4th dimension is is 1.414 squared??
The brother is right on the nipple. An easier way is using your construction calculator that has three buttons. One is Rise, second Run, third is Diag. Times that by the 1.414 for a 45. If you are calculating a 22.5 it would be 2.613. Minus your takeoffs even if your mitering the pipe. Good job!
FYI... not all welders know this stuff, not all welders want to teach this stuff. If you find a welder like him that knows and wants to teach, you listen, take notes, learn it, get to work on it and thank the guy.
Learning all the time great vid Jake appreciate your partner taking the time to show the steps 👍👊👊🙏
U two taught me a lot in 15 minutes.
Nick Johnson man I hope it helps
Wow!! Getting done, thank you for not wasting your time, good job.
Guy McMullan hahaha hope it helped man.
Jake, A^2+B^2=C^2 with a right triangle, take base length square it, take height square it, add those two values together and take the square root of that number. That is the longest length of a the right triangle. Plug in those numbers and you will see that is 16-3/8"
this looks like fun, makes perfect sense and it makes money. you guys are all awesome keep up great videos!
thank you very much
Learn something new every day. Stay safe brother
Travel=H2+L2
Say height was 14"
Length was 8"
14x14= 196
8x8= 64
196
+ 64
= 260
Press the square root button on your calculator v2, then x 1.414= 22"
22" then minus the centres of the 45 elbows, gives u your cut piece travel.
Hope this makes sense. 😀
Same as A^2+B^2=C^2
Is this just for 45 or any degree
What about when the fittings aren’t going to be both 45s?
Hey Please post rest of that and the second part.....that man knows a few things........and it makes sense..... please.
Charles Washington it's coming
Verry Impressive have yet to come across a rig hand that can fit like that great vija
AnthonyLA 310 he's jam up fitter
Very good ....video....actually that page of the book is confusing because the drawings in the example match diagonally and not horizontally.....very good explanation...thanks
The sticker "DANGER: PIPELINER" lol
Ok to find the 1'4 3/8 you use the square but what about if you cant use the square. I know the formula to find the travel is set or run times 1.414 but that is when the sent and run are the same but here you have 14 and 1/4 and the 8 and 1/16. How would you find the travel using the numbers not square.
14-1/4*14-1/4 + 8-1/16*8-1/16 = 268.0664. Then find the square root of 268.0664 --> 16-3/8". If you convert that to feet --> 1'-4-3/8". 1'-4-3/8 * 1.414 = 1'-11-1/8".
man that's badass!!! where's part 2 and 3 and 4 5 6 7..... 😉
Jeff Preskitt getting it finished up
Great video love pipefitting i've done it for 2 years not enough to be a good fitter bt i've learned a couple of things and for big dimensions is hard to use the square, but you can also just make just the the square of 8"1/16 plus the square of 14"1/4 and then when you have the result just make the square root of that result and you have that 1 foot 4"3/8, but because we have the metric system its a lot easier....because whe don't have fractions...then you use the 1,414 (that is the same as dividing 1 for sin(45degree) ) but i love the video, thanks a lot a hope that i have hadded something.
also 5/8 X diameter is the take off for a 45
Or .625
just a question man ...you don't take the gaps fo welding....thanks again for sharing
awesome video Jacob I've been wondering for almost a year of how to do the math for a rolling offset
Blake Arndt hope it helped brother
Ok, for some reason I assumed the 1.4142 value only worked for an angle of 45 deg. The box you have on your iso is not a 45 degree angle across the diagonal so how can you use this value in your calculation?
it is a 45 just rolled. the box is just drawn for a reference
Jacob Schofield , yes, I have been thinking about that. I do get it.
The man is trying to better the industry for that I applaud it but measure 3 time cut once and 👏
but all things considered to much sauce on the taco.🧐
Way more work than needed. 15 seconds on a pipetrades pro and then 2 hole the flanges at the roll angle. No position welds. Good for people who need the visual tho for sure
1.414 is for what? just 6" pipe? What would it be for 10"...
William Cash Same. The formula is a trigonometry constant for figuring 45* offsets. Because you're dealing with center of an imaginary point (the center of the pipe, apex of the bend) the formula is the same. 10' of 10" pipe is the same length as 10' of 6" pipe. Ya dig?
Love your flannel welding shirt I can’t find any cool ones ever how do you find yours?
Your good brother, but I can show you how to do a rollong offset in half the time for whatever degree the specs. ask for. Sorry. ...😎
Let’s see it... don’t just say you can and then say sorry... set up your phone explain how to do it, and send it to me. schofieldwelding@gmail.com
Sounds like a "jam up" fitter. 😉
Bob Langill really really good fitter
AutoCADD. Would take you about 2 minutes to get all your numbers!!
Using the pipe pro calculator would get it even faster using it to its full capacity.
Holy shit, skip all that shit......
Here you go...... A + B squared equals c squared. X 1.414, minus take offs
jeff mason this is a rolling offset. Not just a 45degree rise. Great thoughts though I can see the confusion I tried to film it as good as I could
second vid please
native irnhd it's completely no just finishing it up.
A squared + B squared = C squared x 1.414 - centers.
right you are sir
14 1/4 offset 1 4 5/8 run and 8 1/16 roll
perfect
His (angle) calculation is wrong.. it's supposed to be 1' 3 3/8
Man I e done the math a few times and it keeps coming out the same. Maybe it is the calculatior
Weld gap, 1/8 for each 45°.. 1'-3-5/8 -1/8 - 1/8 = 1'-3-3/8".
I dont want to see any haters on these comments
The roll on the two hole is the same as the degree of roll on the offset ..just level ur travel piece and stick ur angle finder on ur two hole pins
Quinton Johnson tell me more about that
Quinton Johnson can you explain the little bit more about that two holes
:56 the 4th dimension is time
just x by 5/8
Uh what??? 🤷🏿♂️
rewatch rewtch it took me a few times but rolling offsets are no big deal now.
Jacob Schofield will do sir.
Thank you.
Awesome video journeymen!!! 👍
Isaac Gonzalez thank you sir that was all Josh
i got lost halfway, this like advanced pipefitter right?
its just good stuff to know.
