its actually pretty easy to layout those lines with math, say you're laying out a 16 inch diameter pipe and need 16 equally sized pieces cut out of it. You use the formula for circumference, 2 x PI x Radius = Circumference. the the circumference is 100 17/32", divide that by 16 for the straps you're cutting out and then you know the width of each strap or the distance between each line. Use a tape measure or a roll up/wrap around strap to mark out the lines with a ruler that has a V shaped head (center finder head).
The problem with that math is 12" pipe is measured by id, 14" and up is measured by od. So that's the reason for the reciept paper. 12" pipe depending on the thickness had different od. Id = inside diameter Od= outside diameter
@Jacob -- I was just reviewing this older video on cutting a saddle for a branch and I see where you make reference to Page 32 -- which in my book is "Extra Strong" pipe. Isn't most branch test on Standard Weight pipe .250 (which in my book is Page 29)? Just doing a little refresher and was wanting to make sure.
Can u explain which part of this gets a bevel? I️ understand the math But I want to make sure I️ do it right. And also do you have any other pics of the root and cap finished ?
Parker Welding yes you bevel from just off the points through throats. I don’t know how many of these I’ve taken but I’ve never put 8 tacks on one like he said. I only put 4. One in each quarter.
Brilliant video, very interesting. Totally different to any fabrication I've ever done or expect to ever do but it's really cool stuff

for sure man thanks for the comment

Awesome video
Thanks buddy!

.375 wall is most common for 12x12 branch
Best pipe trades videos going. Keep going with this stuff.
thank you sir we appreciate it,
Hey Jake do you only bevel the one piece of pipe or do you bevel the pipe you cut the hole in also
9:38 ...i see your helper did his nails for the camera XD
oooo that's a good idea! great video. been waiting to see this explained! keep up the good work guys
This will help me a lot. ..thanks guys.
You bet let us know how you do
You have a lot of money in pipe right there

The part you saddle should have the bevel if I’m not mistaken.
KEEP EM COMING COWBOY
will do hopefully there helping
Great video!!
how many ft. does a welding rig stay off the pipe line, Please. thanks
thanks Gene hows everything going?
Yall aren’t putting any bevel on there? Just wondering. And what size lead are you putting with your stringer V
Badass! Waiting on part 3
did you find part three ok?
very interesting
thank you sir
Is there not a formula for this like let’s say you were to be making a 36”x36” branch how would you find your measurements to lay out on the pipe
Tig Welder so 36 is 12x3 so for 36 it’s the same measurements times three. 24 would be those measurements times 2
why another video said the dimension is
1) 7/16
2) 1 5/8
3) 3 1/4
4) 4 1/4
robinhoodpapan different thickness in pipes gets you different measurements
for the soapstone breaking problem, have you tried the markal silverstreak pencil ?
I have they are great little pencils
Band saw blade is the best cut that fucker lays better then that wrap around
So you test with your helper bro ???
yes sir jed can lay this out while im welding out the 6g and bh the time im done he is waiting on me for tacks
11:40 that's what she said!!!
So you don’t have to bevel anything on these tests?
Parker Welding yes you bevel from just off the points through throats. I don’t know how many of these I’ve taken but I’ve never put 8 tacks on one like he said. I only put 4. One in each quarter.
can you do a dummy leg/trunion on a 90 degree elbow.
yes sir the next time we do i will record it.
Jacob Schofield is not the same as doing a 45 branch or is it. i can do the branches but the dummy leg on a 90 i cant. idk why.
I believe that measurement is in the black book. We can do one here in a bit and get it laid out for you guys I just need to find my black book.
Jacob Schofield alright will be waiting for it. good videos by the way. i do the layouts on paper but this is a lot easier.
i need a blow book
