Glad to see it's still being taught. it gives your students a well rounded foundation others won't get. Dave

You're welcome! When I made these layout videos, I thought few would even view them! Dave

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 the link NOBOX7. I needed to see this. I'm sure I'll watch it several times. You re the man.

Glad it helped!

+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

Your makin some big templates!

At times when there no one to tell you measurements you have to

You're most welcome!

Never done a teapot spout template! I would bet potters shape those by hand and experience....

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.

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

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.

i've done pretty much any of the layout patterns on Auotcad- sometimes it takes a few tricks to get the layout properly....Dave

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....)

Equal Tee, the point of intersection would just appear as straight lines through to the center of the main piece.

+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

Sounds like a good idea. Thanks.

A great book is "Sheet Metal" by Leo Meyer-

+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.

+Dave Osland I'llalluBBCTCS and

How to make Dom hed

+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

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.....

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!

Your years in the trade will give you a huge advantage over those just entering...

+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

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.
