Hi. Many thanks for a very interesting video. I hope you can help with a small problem I have. I need to cut a hole in a piece of flat sheet metal, for a pipe to go through at 45 degrees. Now I can do basic trig, so it was no problem to find the height and width of the hole. I made a template using an ellipse (I have very basic drafting) of those dimensions, but the shape was wrong. So I'm now wondering: is there another method to draw a template? Do you have a video showing that, or maybe you know of one? Thanks again.
I heard a lot of old school plumbers love using foldable measuring tapes, 1:31 made the reason click. You simple fold the sticks into the vertical and horizontal lines you need, then use those measurements to get the offset
Did he finish? I thought you had to take off for the fittings. A 3" Cast Iron 60 degree take off is 3 ½" inches. So that is a total of 7 inches to take off. 7" = 178mm. So, 635mm - 178mm = 458mm for your travel piece. I'm I right? Do I get a cookie?
Didn't forget; this was originally just a lesson for the center-to-center measurement (although I had mentioned in the opening that this would be the start of what would be needed to calculate the cut length, sorry!)
I would recommend to download an app to your smartphone witch can calculate these things... I use them every so often. (not saying this is not great to master)
Also .707xtravel for 45. If you know your travel and want to find your set or run since they are equal on a 45. Anything like a 60 or 22 just carry a blue book for reference.
Or you just take into account the multiple that are used for givens bends as you were bending conduit. 30 deg angles use a multiple of 2 45 used 1.4 and 60 uses 1.2.
@@Steven-qm2nh measure center to center for 45 offset. Take the number times it by 1.414 and take off the fitting allowance X2 and less an 1/8th for the gasket will give you your number. This guy in the video is over complicating this all needs to be done with a tape measure or laser if needed and a calculator.

I clicked to check if this was engineer humor. Can't you just eyeball this? Cut the travel piece slightly too big then trim down a bit until it fits right?
Yeah you could. But then your nickname would become stovepipe. Anyone that comes into the situation of trying to figure out the Travel measurement between two whatever degree pipe fittings, and they don’t use math to figure out their answer…probably should just leave it up to the professionals. #LU502PIPEFITTERS #MEASURETWICE&CUTONCE
So unless you already know trig to understand the formula he used this video is useless. And if you already know trig to understand the formula he used this video is useless again because you would already be able to figure it out using known math. So useless + useless = useless
what a gift to be able think like this and solve questions....
Keep these videos going you’ll keep real plumber in business

Does offset mean a perpendicular distance between two parellel pipe?

Yeah that's sound , but what if the pipes are 15ft apart and 20 inches in diameter and 20 ft in the air ?
What was the cut piece length?
Excelente máster
Great video
thanks

No cookie for you. 7 inches in millimetres is 177.8 not 178.
He didn't finish. He is supposed to calculate for the pipe actual cut length by removing the take off of the elbows from the hypotenuse length

Nice Video...
how did you get 635mm when i got 1804 something? please rep
How do you divide a length by a degree
Just measure the adjacent side in your diagram and double it to get the length you got. The ratio of sides in a 30-60-90 right triangle is 1:2:√3.
I would recommend to download an app to your smartphone witch can calculate these things... I use them every so often. (not saying this is not great to master)
what ! app
Well I like this one app(lication) called "pipefitter" by tszy. It cost like 6.2 euro but it is by far the best one I've come across ever.
My dads making me make a Christmas tree out of pipes and using this method and i wanted to just have a thanksgiving break 😢
Minus the bends, for the cutting lengths
cool
谢谢您。
60 degree fittings are only used for rolling a wye straight
Very few people know that actually
Just remember 1.414 x c-c. For 45 offsets.
Also .707xtravel for 45. If you know your travel and want to find your set or run since they are equal on a 45. Anything like a 60 or 22 just carry a blue book for reference.
offset times the width divided by length
Or you just take into account the multiple that are used for givens bends as you were bending conduit. 30 deg angles use a multiple of 2 45 used 1.4 and 60 uses 1.2.
nah your wrong. 60 x 1.2 is not 635 mm
When I was a plumber I measured between pipes & added less than the bottom out of the flanges.It took less time than typing this!
I’d like to know more about this

Oh I get it now
Took algebra like 4 times so I am really good at it now lol
Gosh. My brother is very creative. I wish I could do the same
Thanks sir nic
1/12 bend? or 1/8 bend ? I just remember have 1/8 bend in USA
60° is a 1/6 bend
Should be 45s it’s long sweep to reg 90
what you type on calculator ?
I need pipe line drawing image. Please send me
??? T/O for fittings
Why millimeters?
Had to do it in mm huh lol
You forgot to add the FF or fudge factor into your calculations...
mi deseo es aprender a doblar tubing de 3/8 y 1/2 "y desconosco donde me den informacion en español mil gracias
Yo quiero aprender aser plumber
You did everything except show your math work. So someone trying to learn this and hasn’t done math in awhile. Is now screwed. Thanks buddy

550 /sin 60
would be a lot cooler if you used inches
√(635²-550²)=317.3720214 높이(adj)가 나왔고 550÷635=y tan-1(y)=60.01°
빗변길이 모른다면
√(317.3720214²+550²)=635
550÷635=y tan-1(y)= 40.89720308 ???
It's just trig and the Pythagorean theorem law of sin and cosin......

He is pressing 550 twice... why?
635?
fabor de darme esta informacion en español
When I will make 90 then what I will do
seriously you're using mm?
Or just use trig app on ur phone
I typed on my calculator
1.) 550
2. Divided sign
3.) sin
4.) 60
5.) =
What am I missing. I got a completely different number.
Some calculator function steps will require a different order of operations. Try 60 then SIN, and see if that helps.
Make sure your calculator is in degrees NOT radians
@@hunanmilan omg thanks
Please translate to hindi
Adj and set is in the wrong area

He made this too complicated. There are more easier ways to do this. This is too long.
Some one failed basic math here lol
