These videos were so important to me over the years when i was sketching everything by hand. I have since moved on to using Inventor software. If i had to guess, i hand sketched somewhere in the neighborhood of 5000 pieces to be used on submarines. Everything was custom one off stuff based off of templates. Thanks for the knowledge.
Beautiful, any dummy like me could understand this. Of course I had to watch it many times but that's because I'm little slow in the brain. Thanks for taking the time to do the video.
You're like most of us- watch it, read it , practice it learn it! Persistence will get us farther than natural brains or talent! Edison tried 2000 different element combinations before the right tungsten alloy proved the right one for his filament in the light bulb!! Dave
Thanks for this video this is absolutely what Im looking for. This video applies to any notching angle you want..Unlike any other more videos that you can only see tutorial notching all 45degrees😀.Big thanks for this!
Thank you for taking the time Mr Osland. SMW Local 104 teaches this type of layout still to this day. Some of my students have found your videos to reinforce what they have been taught in class. Regards
very cool , i just drew a tangent connection using this method , im so glad you taught me how to do this , however i used a 2D drafting software but i would like to do it how you did for larger shapes , as my printer cannot produce these images easily , i need to watch you again and learn how you used the compass to bisect into even segments
Another great video Dave I did not understand the part about actual pipe sizes I have always made the templates for the outside diameter without any prob I always shape the wall thick ness of the pipe after the outside is cut love the videos
+Hope Smith I've found the pipe cuts don't fit if i go with the outside diameter, especially on thicker (heavy) walled pipe. If your method works, great- Dave
Dave Osland I wanted to thank you for making these important videos for many people thank are getting started in sheetmetal Fabrication and house design Drawing the videos you are dou g will open up many minds and eyes just like you have opened up them for me my question to you do you have a playlist from the beginning of a video that I could start watching thank you kindly from Canada Toronto Ontario Etobicoke North
Hi Domenico- I recommend "SheetMetal" by Leo Meyer to many who are looking for a book that has many straight forward layout techniques. I've designed over a hundred homes and after about drawing 80 with a drafting pencil, I learned auto-cad. It was like going from using a hand saw to a power saw.... Keep learning! it will serve you all your life! Dave
@@daveosland3199 thank you for the information you have given me there are books by Leo Meyer I have put what ever I can get my hands on but I will still follow you through your videos
as asheet metal mechanic this is a must to understand this simple knowledge is worth alot sadly becoming alost skill a pipe fitter, insulator and sheetmetal mechanic three trades this applies to when the journeyman found out I had a grasp on this as 2nd year apprentice they flipped out few of them said they needed raises or they were going to have to quit puzzled the owner questioned why they said they're going to have to pay me out of there pocket because they new darn well he was not paying me enough lol
Dave I can't make sense of how you're able to use the ID for the layout but then use the OD for the final template spacing. Any clarification would be much appreciated.
The reason is because when you Chamfer the branch piece it's actually the bore of the branch that connects with the main. The reason he added the wall thickness is because the template wouldn't meet up on the outside of the pipe he was shaping. You come across this when you use the profile burner. You measure the actual bore of the branch across the outside diameter of the main and then measure down to see how much you are actually cutting out.
Dave Osland last night i tried it on autocad and I was able to make it but it was tedious, may be because I am a beginner in autocad Thanks for this I will be searching your other videos Truly informative I am Pressure vessels and piping engineer and every time this things comes in work I look like an Idiot in front of workers.Because they do it and I even don't know the concepr of it But thanks to you now I know it too
I found using auto cad, I had to overlap , then trim them, to create arc segments for the layouts, among other little"tricks" perhaps some advance auotcad people can comment. (I also have 2008 version....)
I took plate developement classes in college, the final exam was a teapot spout made out of sheet metal. I don't remember how we did it and I seem to have lost my notes and template. Was hoping you'd give it a shot.
great video. I've been learning quite a bit from you. :-) do you happen to have a video for making a template for offsetting the cut pipe on the parent pipe?
+MK116Alex As in a lateral offset? i assume you're looking to bring a pipe into a connection "off-center'. Nope! I use a program like "digital pipe fitter' (no, i don't have stock in the company) when i rarely need to connect things in an offset situation. Dave
I'm putting together a bbq pit at school. I don't want to place the legs based around the center of the main pipe but I don't want them pointing straight down either. If I just do a saddle and move them over then the angle is to sharp. I have access to a blue print program at school but don't know how to use it as the combination welding program only had us taking blueprint reading and sketching.
+MK116Alex Roll a paper tube the same size of the leg you want to use on the BBQ. Make it long enough to "wittle" on it a bit. With a pair of scissors, cut it till it fits as wanted. Unroll it and use it as a template! Dave
Great video demonstration. I've been looking for this for a while now. Just finished my apprenticeship and they didn't teach this at all. I asked quite a few of the instructors and no one knew how. Quite disappointed I was.....until now! One question, when you say inside diameter can I use nominal dia or does it have to be actual inside dia.( -wall thickness times 2) Ive laid out for 40 sched and up pipe and am using nominal dia. I hope this will still work because I just made a ton of them 4" right up to 10"
+mortdiver Do they fit up? The first time i did this I used the outside diameter, because i learned pattern making for sheet metal. The 1st one wasn't right and i realized i needed to go with the inside diameter- i.e., say 3" inside instead of the 3 1/2" outside on a sch. 40 3" pipe. Even though there are programs for pipe templates or even things like "PlasmaCam", there's a added value in knowing how to layout templates instead of just doing it on a computer! Dave
I agree. I enjoy making them myself. I have yet to try them but when i get back to work I'll give them a try. If they don't fit then I'll redo them with actual inside dia. Thanks for the video tutorials.
Nice Job with the demonstration. I like this method. Quick question and i think that I already know the answer...How did you determine the length of the 3 inch pipe when you drew the overhead view? I believe that it doesn't matter, because your template starts from a straight line, and the lengths of the projection are relative; however, I am not positive. thanks
you are using 15 degree on your circle instead of 12 so that you are getting more accurate due to the process in which you are fabricating the fitting?
ive been in the sheet metal trade for 26 years now. I am going into Mohawk College here in Stoney Creek, Ontario as an instructor for the Basic and Intermediate level of the Sheet Metal Apprenticeship. I haven't been in school for a number of years and haven't laid out a round reducer or a lateral in a long time. Just brushing up on pattern development before hand, hahahah. Your videos are to the point and easy to learn from. Great job!
Around 2:00 you explain that the 3" pipe template has to be drawn with the inside diameter. I do not quite get the reason for that, so I would like ask you to explain why the template drawn with the outside 3.5" diameter will not fit, please.
+Hans Henrik Larsen On pipe, the inside diameter differs substantially from the outside. if the outside diameter is used, the template makes the pipe too "tight" on the joining. if the templates are used on sheet metal, there is minimal thickness difference inside vs. outside. The 1st time i used this template technique on pipe (after using it successfully on sheet metal, i realized i had to lay out the template from the inside diameter- it then worked! Thanks for watching these "nerdy" videos! I'm quite amazed as many people have viewed them as has been done! Dave
+Dave Osland It is great series of videos on how to do these things. Well, it is a bit embarrassing for me to admit but I have actually worked as sort of a piping engineer for quite some time now, but I do not have any experience on how to actually fabricate the stuff in the shop that I have been designing. I just draw an isometric drawing asking for a pipe welded on to another pipe at some angle. I have done tons of flow and stress calculations without bothering the practical aspect of building the stuff. And so I stumbled over your videos and it really caught my attention. Now, another question: Do I need two different templates for a 3" pipes with different inside diameter, say, a sch. 10 pipe and a sch. 80 pipe? And do I need to take into account the 12.5% tolerance on the wall thickness as well?
+Hans Henrik Larsen I would make different templates for diff. scd's.. There is a huge difference in a scd 10 vs. scd. 80 wall. I come from the "blue collar" side of things where i don't know squat about flow and stress calcs! I just have to know how to layout and cut pipe for the fab/construction side of things- Dave
+Mart Mc Over yonder here on the other side of the "pond", "the pipe fitters blue book " , by Graves, is widely used. I've learned a lot of sheet metal layout from "sheet metal" by Leo Meyer- Dave
As an accomplished plater and welder, you have made a "technical" error in your plan view. You should have also allowed for the pattern to wrap around the outside in your elevation.Also in the plan view, the top of the 3" branch eould be elliptical not a circle.
Sir, you are mistaken. If the end profile of the tee branch was drawn, it would indeed show as an ellipse. However the semi circle as drawn to divide the perimeter into parallel divisions and project down to the body of the main pipe to determine true lengths , is correct, as he cross section of the pipe remains circular.
Dave Osland I have found the books by Leo Meyer I would care to follow you beacuse I can see much more information I have found the books by Leo Meyer in the public Library where I live in Canada Toronto ontario

Good technique. Can you make your numbers legible?
Dave I can't make sense of how you're able to use the ID for the layout but then use the OD for the final template spacing. Any clarification would be much appreciated.

Love your tutorials Dave,
Have you ever done something like a curved and tapered teapot spout?
Never done a teapot spout template! I would bet potters shape those by hand and experience....

Thanks you sir but I have a doubt..Pls. Show me sir Another Video for Top View of Header hole Making...
i like it .
you are using 15 degree on your circle instead of 12 so that you are getting more accurate due to the process in which you are fabricating the fitting?
glad it was of use to you. When I made these I thought only a few would be interested...! Dave
Dividing the circle into equal segments creates 22 1/2 degree arcs. Any smaller divisions makes for a messy/busy/ drawing.....
