look up the geometry for doing equal arrays. I had a sheetmetal fab guy shiw me that. anything in a radius or compound radius can be exsplained in an array.
Man thanks a ton! im not a pipe fitter by any means but my job chasing rigs kinda requires me to fit pipe every now and then, so your videos and teaching definately aint fallin on deaf ears!! again, thanks a ton!!
Best way to learn from a professor of practical knowledge in real life situations. Lessons like this will never be forgotten. Appreciate the time you spend to share your knowledge.
Thanks Jacob, this couldn’t have come at a better time as I’ve got an 8” shed 40 stainless job I’m about to start and was wondering how I’d go about getting my mitered fitting spot on. Thanks heaps for the effort you put into your content mate 👍🏻 cheers from Australia 🇦🇺
Not trying to be a dick but I dont think you did your math right or maybe I haven't done my math correctly LOL. You should use the blue book to get the measurement of a 6inch 90 (9") then add half the pipe size to get your OD radius (12 5/16) then for the IR you would subtract from 9". Let me know what you think keep the vedios coming one of the best channels on here.
This just how I’ve always done it. They have not been wrong yet. But there’s probably 100 ways to figure it out. That’s just one of them. I’ll check again and if it is wrong I’ll delete this video and edit it lol!!
@@JacobSchofield dont delete and I hope you didnt take my comment in the wrong way. Dont stop doing what your doing wish I had somthing like this when I first broke out hard to find people willing to share what they learned the hard way. I'm going to try wrapping mine with a 100ft tape never tried that way before might work out better for me.
The blue book has a formula for this but it’s based on the actual inside and outside radius (aposed to the circumference that was used in this video) along with center radius wich is one and a 1/2 times the pipe size for a long radius 90 the added benifit for the blue books method is you can calculate your take off
Hi I’m 22 years old and have no knowledge of welding but wanting to know more, any advice or do you have a video on suggesting how to start and what to know. Thank you
Great video tutorial young man. The Stabila level that you have has a bezel that will indicate the degrees of an angle. So, if you turn the work piece vertical and place the Stabila across the pipe (you may need to rest on apiece of steel to bridge the pipe) you then turn the bezel until the bubble shows level. Look at the degree markings on the bezel ring and it will give you the angle.
Excuse me Jacob, is there a name for the rotating wheel with the clamp that you used to hold the 90 degree piece of pipe at the beginning of this video? Thank you.
Have you ever seen someone show up with a portable generator and a inverter stick welder as their setup and if so, did it work out? If not, do you think that kind of set up would work on the pipeline for someone that cant afford a " real " motor generator welder like a sa 200 or a pipe pro when just starting out?
Thanks man, would the kerf of the oxy cut take away a degree or so from that left over pipe, so say you done a 25 and then a 65 the 65 would actually be 64 degrees ? Or is not that critical of a thing on large pipe? videos are so helpful :)
The kerf would most definitely make a difference. If you really have no choice, then hopefully you have a very steady hand. Best thing to use in any case would be a 3/32" cutting disc, if you're really looking to be precise, though it may take longer especially on bigger bored pipe. You will more than likely lose a bit of length between the cutting/grinding process anyways, but not so much that it would not be workable during the fit (weld gaps). I usually wait until after the grinding process to do my takeoff lengths, so that I still have a way out with my final cut lengths between the mitered fittings. Most of the time, in the construction industry, you won't run across too many instances where you'll be having a mitered cut going directly into something critical i.e. pumps, compressors. There are usually breakout spools, valves, and various flange make-ups between to compensate for alignment and stress, so you do have some leeway for a degree or so. Not always the case, but mostly. I hope that was helpful, take care.
Just did some 66 inch miter 90s. It sucked!! Glad I had a plasma. Can't use a digital on a fitting that big. Measure twice and cut once when messing with that much money. Good video.
Jacob Schofield love the content. I would love to find out how much money you have generated for other welders through your videos. If you knew that, you could market an online school taught by “Jacob Schofield: the $100 million welding teacher”.
Sorry to be a Poindexter, but for the O.R. you reference, 25 x 3/16" is 'not' 5 and 1/8".....it's 4 and 11/16". Likewise on the I.R., 25 x 1/8 is 'not' 2.5", it's 3 and 1/8".........so perhaps the O.R. and I.R. numbers you are giving might be "generated correctly" by some table buried in your Construction Calculator algorithms, but the "formulas" you are showing people in the video are not going to yield the "answers" you are showing.
Oh yeah I’m sure there are different ways for sure. This is the way Ive used for almost 10 years and I have yet to have one go wrong. This is how an old timer showed me how to do it when I was helping him. Thanks though brother I’ll be checking this comment out more in detail cause I’m always up for a new way.
@@JacobSchofield Hey Jacob, thanks for the reply..........but I'm asking about this because I was trying to learn "how" to do it! Again, multiplying 25 times 3/16" does "not" equal 5 and 1/8"..............so "how" or "where" do you get the 5 and 1/8" that you use to "properly" mark the pipe? Is it a special button on your calculator? If so, what kind of calculator are you using. Similarly, 25 x 1/8" is "not" 2 and 1/2". At first I thought it was just a typo, but then when the "error" appeared to be made on both the O.R. and I.R. calculations it became apparent that you were using some other kind of "math" to get those results. Thanks again for any additional info you can provide us!
@@JacobSchofield hey Jacob great video but y ok u just replied sayk g an old timer taught you this but it makes no sense you didn't explain how 1/8 × 25 = 2.5 ? What are you taking off 25/8 is obviously 3 and 1/8.really love your videos also
@@JacobSchofield also 3/16 × 25 is 4 and 11/16? Way off from y pi ur answer please clarify what your measurements are taking out for or just let us know you made a mistake cut there ain't now way that is 25 degrees going by your formula it would be 3 1/8" ir 4 11/16 or
Maybe I'm wrong, not a pipe welder, but isnt actually your outside/inside circumference of the bend, not radius? I understand what you mean by watching, just the way my brain processes it is different
ChasinDreams, Son, you can add "Construction Master Pro" app to your Cell phone, for a one time fee or you can buy the Construction Master Pro calculator outright on Amazon. Several are offered (make sure), before you pull the trigger.
Thank-you, this solved the problem of the crooked riser👌👌
look up the geometry for doing equal arrays. I had a sheetmetal fab guy shiw me that. anything in a radius or compound radius can be exsplained in an array.
So what if I want to make a 21.5 half fitting?
Thank you!
Awesome vid
Thanks Ray
Thank you for the clear explanation.
I appreciate you taking the time. Thanks, very helpful.
Glad it helped out.
You need the 57.25 rule. It is a very accurate way of mitering to any angle.
Thanks son,God bless you 👍🇺🇸
can i please know how do you call that style of articulating vise with the top wheel. thank you so much for the vid... GREAT TIP.
Roll out wheel
thanks!!!
Awesome video!
Thanks Travis
Man thanks a ton! im not a pipe fitter by any means but my job chasing rigs kinda requires me to fit pipe every now and then, so your videos and teaching definately aint fallin on deaf ears!! again, thanks a ton!!
Now this is a great learning video right here a big help out buddy good job.
Glad it helped out Melvin. that means a lot.
The formula Iv always used and was taught was 0.01745x OR/IRxDG. Which comes up differently than what you got. But my degrees never been off
Thats so helpful, thanks
That is pretty slick...
Nailed it
Radius x degree x .01745, ua pipe welder n fitter
Done did 8 miters bytime you did 1. Hurry up field hand.

Digital inclinometer is the word you were looking for
Yes there is those and digital levels both work well
Who needs notes when you can just come back to this video and refresh

Very nice information thanks keep them coming
When you gonna do a video on how to build a roll out wheel
Great video tutorial young man.
The Stabila level that you have has a bezel that will indicate the degrees of an angle.

That’s awesome and super simple! Thanks
If I’ve never been a welder helper or been around welding to much; could I still apply for a welder helper job?
Ofc! Just be willing to learn.
Always learning something from your videos...your a freakin great welder and awesome welding instructor, KEEP UP THE GREAT WORK!!
Measure twice cut once
Excuse me Jacob, is there a name for the rotating wheel with the clamp that you used to hold the 90 degree piece of pipe at the beginning of this video? Thank you.
My roll out wheel? You can buy that same one from off the hook fab there about 1100.00 now.
The radius never changed so you could have used the original numbers for length per degree and just multiplied by 20 to get the mark for 45 degrees
Right I was just explaining if you had that piece sitting g in the parts pile how to do it again.
Have you ever seen someone show up with a portable generator and a inverter stick welder as their setup and if so, did it work out? If not, do you think that kind of set up would work on the pipeline for someone that cant afford a " real " motor generator welder like a sa 200 or a pipe pro when just starting out?
Love the way you say root
Got a question for ya. After you miter the fitting is there anyway to figure up a take off?
Squares will help you figure that out I can do a video on that
@@JacobSchofield that would be pretty cool to see man!
I thought America was advanced, but when I see measurements in feet and inches, its like going back 2 the Neanderthal era.
JOHN HILDER we like to be different
Holy s*hit, using inches makes this complicated😅
Great video. I do cylinder angle findings so this math makes a bit of sense but I did get lost a slight bit after you left 90 to 65.
65 is the degree after we would cut of the first 25 degrees. That’s what would be left over does that make sense
What calculator aplicaction do you use?
Please let me know i enjoy al your video.
Thanks brother.. awesome.. please share more pipeline fittings.
Good job!!!! Just another day at work!
Not to bad brother fit just like a glove thanks for the tip that work great be safe and keep on welding
Try a machine shop and a lathe,they knew this was coming and you saved no time making a close to accurate fitting
right handy
Thanks for the helpful information I’ll remember this if I ever need it in the future thanks again 🙌🇺🇸

do you know the pipe trades pro calc will give you all that?

Lol, pretty cool instructions, but reminds me why metric is so much better
If your trying to get anything less than a 45° fitting why not use a 45 an use the same formula an just divide by 45 instead of 90...just a idea
If they give you 45 it would be a lot better but I just had the 90
