      Sometimes when I'm all twisted up sideways and down in a soffit or drop cieling it's hard to shoot a reasonable close visual 45.Are they an advantage especially on cast waste?
      Copper's not as hard to get as the fittings set on the pipe in the sockets.
      Buckets are almost synonymous with plumbers here....I know a few who use bags or toolboxes, but most use buckets with maybe a tool jacket...I think it's a regional thing. Sorta traditional in a way.
      I was always taught they come in handy when a sudden leak happens...dump tools and position it so you can run to the main shutoff in an emergency and minimize flooding, also a great stepping stool or seat when needed.

      And yes...I used the folding rule on commercial...on a twelve foot ladder when there's an offset a few feet too far to reach with a conventional tape it's fantastic to be able to get the measurement without having to climb down and relocate the ladder... especially when you have a ton of offsets to cut in over the course of a day.

      First few times I tried the 1.41 rule, I made the usual mistake of measuring face to face as if I were cutting the pipe like usual on copper.
      To get the right offset, it has to be measured center to cventer on copper, PVC/DWV you have to subtract twice the fitting makeup after the center to center X 1.41...BM too.

        i use a bucket to and only bring in the tools i need to do the job .

        im not good at the math thing to ,when my welder is on the job working with me he does the math . other then welded pipe i will put the 45 on one pipe the use a piece pipe a little longer then what is needed then hold the other 45 along side the pipe moving it up and down until it is in the right spot and mark the pipe

        after doing it this way for years i got very fast and it works for me

        but i should learn the math thing

              without looking like to much of a dork,I carry one in my bibs and a couple backups in the glove compartment.

                  Re: Folding rule

                  I do everything with a 6 foot folding rule, the apprentices hate doing gas pipe with me because they get told I need a piece 6 foot 27 3/4 inches end to center of a 90, and they have to do the math to convert it to inches to read on a tape.

                  For offsets I just do the math, using the formula for the fittings I am using, for rolled offsets I use the formula to arrive at the distance, and then use the formula for the fittings I am using for the rolled offset.

                  I know, I'm a Neanderthal.

                    Re: Folding rule

                    I almost always use a 6 footer, never really learned how to use it for the 45's.
                    Just used the math 1.414 for the offset minus the fitting takeoff.

                      Re: Folding rule

                      I do have a book titled math for plumbers that we use for the apprentice classes. I'm not at the office all weekend because I plan on two days of fishing. but I will post the title monday.

                          I just drove to the San Fernando valley and picked up Thomas Frankland's "Pipe trades Pocket Manual" along with City of Los Angeles's 2008 amenndments to the U.P.C..Thanks for kicking me in the butt in the proper direction.

                              Since we work mostly with innexpensive pipe(for the most part),2-4 cast and 1/2-2" copper.It has been just as economical(time vs. material if cut wrong on the first cut) to cut off visual holding the fitting in approximate place.

                              If I'm in open field,say for instance full under floor uninterrupted lid I use the formula.Where I have been lately there are too many dodges and elevation changes.The lids are a nightmare to offset through.Too tedious to get consistant numbers off.Got my formula's now,time to get into even faster habits.

                                I would suggest that you contact Lufkin division of Cooper Tool Group and even more so L. S. Starrett. I know Starrett has educational material that would tell about all kinds of measuring and what tools-instruments to use.
