  • 45 degree framing square

    hey guys,

    i'm a union pipefitter out of colorado and was working a shutdown a few months ago and a co-worker pulled a full length 45 degree framing square out of the gangbox. never having seen one before i was excited. after asking him where he got it i was disappointed when he replied that it was a hand me down from his father. anyone that is familiar with pipefitting can attest to how big of a pain in the *** it is squaring up large 45 degree fittings by yourself. if anyone knows where i could find one it would be much appreciated. i have looked all over the internet and have yet to find anything. thanks again.

    I have fabricated my own adjustable compass out of two 18" pieces of aluminum flatstock with a 1/4" carriage bolt and wingnut.Use it for snapping out layout on big subterranian jobs.My marks are still in the parking garage on Sunset Blvd. in Hollywierd.Measure the inside of the two ends for an exact 45 degree angle,write that number on your new tool.I keep it adjustable so I can do 22.5 and 60 degrees.

    Show that off to you old timer buddies.

          not ringing a bell. am i missin something here.

          drtyhnds- great idea, i like it and may end up doin just that if i can't find one. im young and just turned out of my five year apprenticeship six months ago so theres alot i still have to see and learn. i enjoy seeing some good improvising. i especially like being able to use it for 22 1/2 fittings. nice thing is you could make it as long as youd like or need. i worked with an old navajo plumber up in telluride one winter and he had a homemade tool box packed with nothing but homemade and modified tools. some pretty cool stuff in that box.

            I made an adjustable one (well about 6 of them all different sizes) out of stainless flat bar. Fitting and welding big pipe by your self is more than a one man job.

              See just like that.
              Why buy one when you can make a better quality,more personalized one,to more fit your needs.

              For less money!!!

                This looks promising.

                How about a patent search?

                  Any fab shop should have CNC plasma table. At that point they can cut you just about anything.

                    Fitter ,welder taught Me this, and I used it a lot.
                    drive a nail in a full sheet of plywood bottom edge center up 1/2".
                    Now hook your tape end in nail head which is up 1/8" off plywood At 28 1/2" pencil in a 57" diameter 1/2 circle. Mark off every " and
                    each inch is one degree. This was 25 Years ago, hope I got it right
                    Tozz will know.

                      IF I am figuring correctly ever 1" would equal 2 (two) degrees, ever 1/2" a degree,

                      57 X 3.14 = 178.9

                      360 / 3.14 = 114.54 diameter for 1" a degree

                      180 / 3.14 = 57.32 /2 = 28.66 is nearly exact which would be close to 28 5/8"

                      thank you very much tho, I had never thought of making a king sized protractor,

                        Here's a design for aligning a weld neck or slip on flange thats pretty simple. 2" wide out of 1/8" plate all the way round and on a CNC table it's perfectly square.
