Thank you for posting this tutorial. I asked myself "Do I have to use calculus to make a template that I could wrap around a pipe?" I did a search " how to make a template of 2 pipes intersecting at right angles" and your video came up.
I was a combination pipe welder and fitter in the offshore industry for five different oil companies and this type of information was wanted by a lot of welders that were good welders but not fitters they used to buy the templates already made up from a man out in Mexico that was sold in a welding shop out of Venice Louisiana and Matthews Louisiana templates were a high desirable thing desired by many welders who did not know this type of knowledge on how to make their own templates but having this knowledge saves you a lot of money because you can make your own templates of every type of angle before you even go off shore of course there are other tricks to take one pipe and sleeve it into another on a horizontal or any type of angle there is a trick that you can do with multiple welding rods if you don't want to draw out a template at all and it's quick and it's very fast but I don't have the time or the means here to go into that but this gentleman here that posted this video is doing welders a lot of favors here by showing them how to make their own templates especially when you go for a job where they want you to be a fitter as well as a welder I'm retired now and have been for years but I love the trade of welding and fitting
Great job this is the layout I learned in my apprenticeship and now our apprenticeship doesn't teach layout anymore they only teach how to program a burn table I'm glad you take pride in the education of our youth I hope they find this!
I learned this 30 years ago in trade school but haven't had to use it in quite some time, thank you for refreshing my memory. I just used auto cad using your video to make my template and got it done. Thanks again.
I’m 27 just learning how to weld. I decided to build a swing set out of 4 1/2” pipe for my kids. I only have a cut off saw to cut it with, which has a 45 degree angle to cut on the base. But I really wanted to make sure (because the pipe was so large) that I could lay out the correct angle on the pipe to double check where my blade laid. Thank you for the information. Feels good to learn things like this.
If you happen to see this. Couldn’t I (for time purposes in the future) wrap paper around the pipe, cut it where it meets, and then divide each half from the middle by 8 and lay out my 1/8th measurements that way?
Thanks for a refresher course on this. I have done it before, but got stuck. Now I can walk into work in the morning with confidence and finish my layout! Thanks Again!!!
Thanks, hadd to cut scaff pipe to 66 and 32 degree angle and felt pretty smart being able to use this. Felt equally stupid not remembering or seeing the use of learning this 15 years ago in school.
That was old school awesome! I can see why you wouldn't want to do that for a production run of 100 fittings, but for us backyard garage fabricators? PERFECT!
Excellent step by step sequence I still teach sheet metal layout old school seems to be new school You are a excellent craftsmen and skillful sheet metal worker
For those curious when he marked the x's for the halfway point theres no set distance just make sure you dont make a mark and then change it on the second or it will be off. I learned that just now
@@t_train3796 distance the two points on the wing divider to roughly 3 quarters of the distance between points for the template. They will intersect. Just make sure it stays the same or will mess the whole thing up. Lot of trial and error
I'm also used to using my bluebook. I think this comes in handy when working on anything under 4" pipe, you can use a better grade paper and keep it in your box for later.
Very easy to comprehend, you do great work. When i was an Apprentice learning my trade,what happened to the formula that we were once taught ie, Mean diameter x 3.1416..??
this was very helpful. I ended up finding a calculator online bit it's great to know how to do it. What I would really like to see is how to cope square tubing to fit pipe. I have a project and I need to mate a 4x3? or 2 to a 16 inch pipe.
+MK116Alex A 4x3 to a 16" pipe will have only a slight arc to fit. i would probably make a slight cut with an abrasive blade in a 4 1/2" angle grinder and then clean it up with a grinding disc.- Dave
9.42" would be closer to 7/16ths, or .437". Thank you for the video, a friend and I used it this evening to lay out 12.75" dia pipe for a weird angle, all we had was a long and short measurement, no angle, but after some Keystone Kops antics, we pulled it off
mohsin ali, the height is however long you need it to be. The length of the "cut" will always be the same for this angle on this size of pipe. Pipe isometric drawings are nearly all dimensioned along the centreline of the pipe.
It would be excellent to download a video teacher where step by step detail how to draw interferences to different degrees but in the same tube. since it would help many of the beginners in this branch
OK, love the video and the technique, and obviously it works. But it looks to me, for the layout of the 16 segments on the long line, at 4:26, you measured not arcs, but chords which would define an inscribed polygon, which would have a shorter circumference than the circle you are working with. And yet the cut out template fits the pipe, and I can’t see why. I don’t think the 1/32 inch gap in the conclusion explains anything. Dave? Anyone?
And could you make video on how to make mal for the main hole cover with 28 or 29 holes or etc.. for main hole,, Iam interested itu would help me much in my job,,Thankyou,,
HI Dave - Watched this several times. Your instruction is very clear. One thing I missed and haven't figured out. How did you determine the length of the initial segment you divided into 8 sections? My finished template was too short because my initial segment was too short. Thanks
Awesome video as of right now a subscriber my only question is when laying out the drawing of the pipe how do I know the length of the pipe I understand size but I don't know the length ???
Good question. You can use the compass at various lengths- Just swing the arcs from each vertical and horizontal intersection lines. Obviously, the length has to be able to reach out beyond the semi circle. the arc crossings will perfectly divide the section. Give it a try. It'll make sense when you try it a time or two....- Dave
Your taking a straight measurement with the dividers on the bottom half circle when its actually an arc. if your off by a 64TH of an inch times 16 spaces you will be short 1/4 in. just a tip from a master sheetmetal worker.
+Brent Hick the difference between the chord length and arc segment length (at 22.5 degrees) on a 3inch diameter pipe is .004inches (.585 vs .589)...it's only .007 difference on a 6inch dia pipe. As long as the correct semi-circle was drawn and divided correctly I don't see how it's going to be off by 1/4 inch? I guess that's why he said to double check the length of the line (which would be an approximate circumference) at the end to see if it was near 2(pi)r--if that measurement was off by 1/4 inch then definitely something went wrong...especially on a 3in dia pipe.
I did this and I've double checked it in my total length of my total length of my template does not match but total length of my pipe I'm doing a 24" pipe Corrugated

Grammar is much needed my friend
He's a tradesmen, all he needs is technical know how and understanding mathematics. He couldn't care less about his GRAMMAR lol @@raulgallardo5014

AutoCad is a great skill also!!! Dave
Most shops are using software nowadays, but knowing these layout techniques give us a better foundation for our trades....
Dave Osland Hi how to make Dom had
Amen
I like every video that teaches me a new technique, even if it's really simple. Like how you divided the angles on the circle with the compass. GENIUS
I learned this 35 years ago but haven't used it in awhile. Great refresher course. People be surprised at what they can learn if they listen.😊
Couldn't agree more! Dave
I have been looking for information like this for a long time and here it is! Very understandable and well presented. Many, many thanks.

You are a excellent craftsmen and skillful sheet metal worker
Your students are getting a foundation many lack that don't know these principles/techniques.
Dave
Such a great video. Thank you for sharing this knowledge with the world, it's exactly what I needed to know.
Very nice tutorial . I've used this method to mark sona tube before. You simplified the instructions very nicely
Thanks!
For those curious when he marked the x's for the halfway point theres no set distance just make sure you dont make a mark and then change it on the second or it will be off. I learned that just now
Thank you. I've been racking my brain comparing what I'm doing to him and not getting the same results.
@@t_train3796 distance the two points on the wing divider to roughly 3 quarters of the distance between points for the template. They will intersect. Just make sure it stays the same or will mess the whole thing up. Lot of trial and error
Thank you for sharing this knowledge! If has helped with a current job.
Very good tutorial and such a unique technique. Thanks for imparting your skill.
securityrobot , this is not unique. This is traditional parallel line development
This knowledge is helping to those people which are need to learn. Thanks a lot
Brilliant piece of work
Thank you sir.. Excellent ezplanation.. cheers from srilanka👍
Pradeep-
Does me good to hear from people around the world!
Dave
Thank you for sharing and I would to say, is what they call a mitering pipe method? This a great learning show you have.
Thank you thank you so much Dave Osland ,. A real mentor you're amazing
Dude, well done good sir well done. Great! Video and very very helpful. Thanks for your time and knowledge.
Thanks for the explanation. You can fold the sheet in half along the long line when you cut.
I have watched a pipe fitter using the wrap method and a pipe fitters manual and it was far quicker and easier but your approach is interesting.
I'm also used to using my bluebook. I think this comes in handy when working on anything under 4" pipe, you can use a better grade paper and keep it in your box for later.
That is very good I've learnt a lot thanks for that
when you use this leave one side longer and overlap the wrap. on heavy wall pipe don't cut the shape and just center punch through the wrap
Very easy to comprehend, you do great work. When i was an Apprentice learning my trade,what happened to the formula that we were once taught ie, Mean diameter x 3.1416..??
I love your video..pipe fitter from phillippines...
Thanks from the U.S.!

Thank you sir. Yeah I figured it probably wouldn't really require a template. I can be so anal at times. I think I should have been a machinist. :-)
I'm impressed, slick trick.
welder fitter this is not a trick, it is traditional parallel line development technique.
that was amazing thank you a lot i have watch all of you videos honestly it really helpful thanks a lot God bless you i'm very happy
great videos while watching them i really haved learned a lot thanks a lot

Very interesting process. Thank you for sharing. By the way, I use SolidWorks software with sheet metal option. I unfold the cut and print scale 1:1
Your videos are very helpful ♥
Very clear and much undrrstood..thanks
its so easy to understand . . . u are great sir thank u so much

Wow good explanation , thank you
Can you make a video on how to make a layout for saddle pipe? Having trouble finding a good video on how to properly explain how to do it.
Thanx buddy u solved my problem thanx a lot....
You dont need the compass to mark the points across. You just project the lines at 90° to the lines on 1 to 1.
instruction is very clear.,.,wow excellent sir
Pipe fitters blue book helps make this super easy.
Yep! a handy book!!
what about the layout of eccentric dummy support. I want to know how to layout the eccentric dummy
And could you make video on how to make mal for the main hole cover with 28 or 29 holes or etc.. for main hole,, Iam interested itu would help me much in my job,,Thankyou,,
Thank you sir, Practically small bore it is worked but big bore possible?
I would add glass tape onto your tracing So you can have it for a indeterminable life. Nicely explained !
HI Dave - Watched this several times. Your instruction is very clear. One thing I missed and haven't figured out. How did you determine the length of the initial segment you divided into 8 sections? My finished template was too short because my initial segment was too short. Thanks
I'm pretty sure the initial measure is the radius of the circle.
Darryl Braun No, it's the diameter of your pipe
Thank you! Clear and precise.
Wow, that was clear, thanks ! (Now, how do I apply this method on a 16cm diameter wood log ? *looking for a big enough piece of paper*)
2 sheets of A3 paper taped together
Superb instruction ........Thanks for your time.
well... thank you!!! Your most welcome!
When I made these layout videos, I thought only a few people would find any interest in these.....
On The Job, Have Used This Many Times Nice Video Raphaeldiy
sir your a genius person. I like your drawing skill.thanks for replying me.
+Thamim Basha
Not a genius at all.. just took the time to learn, as anyone can!
Sir ,could you teach me a 90degree bend pipe making by four pieces drawings.
+Dave Osland cool pencil.awesome vid
+Denz m very kind of you sir.
Nice sir tq for sharing...
Awesome video as of right now a subscriber my only question is when laying out the drawing of the pipe how do I know the length of the pipe I understand size but I don't know the length ???
Thanks for the vedio itu could really help me in my carrier,,great
Can you do this same lay out for any degree?
very helpful.. thank u sir.. plz teach me, how to make 90degree round elbow in metal sheet?
jana tvr

have you special sweep saddle 90° elbow calculation
Dave, I did not see how you got your second set of arcs I saw you adjusted the instrument but did not see what you referenced
awsome... can u show how to make Tee joints
+Valdimar Tjørnudal
see "making a 90 degree pipe connection" (Dave Osland)
Super very good 👍
Thanks for the visit
awesome instruction keep it up.. man...
Thanks!
a very useful video thank you very much..
Thank you for the video, good tutorials
How can i get the length of the elbow or the vertical marking that you make
Great job!!!!!
Thanks!
you threw me back to high school!!! :) thanks!! where's the T square ruler??? :P
Excellent method!!
How do you do a 3 peuce segmented 90
Sir, how to make template for two curved pipe joining together
thank for making and post video, i can see and learn, thank
Thank you very much for your guide line.
+Faisal Mahmood
You're very welcome!
Nice. You started with the angle and length. The is 45 but how did you get the Height
Read reply I sent to person below by mistake
how do you set the compass up to divide the semi circle into the parts? just divide in half over and over?
Good question. You can use the compass at various lengths- Just swing the arcs from each vertical and horizontal intersection lines. Obviously, the length has to be able to reach out beyond the semi circle. the arc crossings will perfectly divide the section. Give it a try. It'll make sense when you try it a time or two....-

hello, I want u to mark 45° lateral on the pipe with 16 or more lines.
Excelente. Método de. Triangulacion. Ok. Saludos desde veracruz
can u plz tell us how to make cyclone snail segment piece calculation or marking
You lost me on that one.....
Dave Osland rashidaali1983@gmail.com send me mail i will send you the dwg or sketch and i didn't want to lost you dear sir
what type of paper you use
it's hard to see in the video, but the "fad-out" blue ,1/8" gridded drafting paper- Makes it easy to keep everything square and on track!
excellent Sir.
sir can you please post how to fabricate,,' Y ' type piping cut and lateral cut for unequal size.
thanks in advance
Muhammad Saeed I'll do a 90 and a 45 (wye) template- Dave.
thank sir,
How did you get 90degree of the 3"pipe drawing?
Half of the total internal joint angle. Therefore the angle in the elevation is 45degrees.
Gracias por el tutorial y muchos éxitos
Gracias de Guadalajara Mex .
Can that same template be used for smaller pipes then 3inches?
no. it is only good for a 3 inch od pipe at a 45 angle
This method can be used for every size of pipe mitre and angle
can you show me how to cut a degree from elbo ??
You didn't show us how you got the angle
I did this and I've double checked it in my total length of my total length of my template does not match but total length of my pipe I'm doing a 24" pipe Corrugated
