If you check your book, it will tell you specifically the math for factory 45’s and field cut 45’s (because there is a difference). Some companies will order 45’s and others only order 90’s and therefore you have to make your own 45s (and odd degrees) And the trick to making odd degrees is a whole other video. (Quite simple however, just measure the bend, divide that measurement by 90, then multiply that number by your desired angle)
A aweasome trick for laying out odd angles is the 57.25 rule. You draw two lines using a square and draw a arc 57.25 inches 90 degrees. Then every inch on that arc is 1 degree. Then just mark the arc by flexing a stick ruler for example 20 degrees would be 20 inches on the arc. Snap a line back to center for your desired angle and draw your fitting. You now have 3 coordinate measurements for any angle on any size pipe.
Somebody needs to do a video on the 57.25 rule. You can also find coordinate measurements on saddles. I don’t have a camera or the computer skills for a CZcams video.
Very easy to understand
Good info. Brings back hacks my pipefitter/welder father taught me 50 years ago. They young-uns need to know this.

Can you please make a video of how to do a Mira join?
he has a lot to learn on this
What is up with the pistol on the back of the truck?
Good video

Nice
Bonjour monsieur je voudrais savoir si vous pouvez traduire votre vidéo en français car je m'intéresse à ce que vous faites
How long you been wielding. I've been fitting in the plants and shop for 7 years.
