This is what should have been taught in school. I will definitely show my daughter this. I always maintained what we learned I. School was not practical. You, however. That's an entirely different story. Putting mathematics where it's needed. I recently learned trigonometry then proceeded to work out the formulas on spread sheets. I'm making some frames from discarded fencing posts and have made some jigs to cut with a cold cut saw. Well done and thanks for uploading.

To get a more accurate template, you can simply take the O.D. 3.5 * pie / 16 = 10.9956 / 16 = .6872. Use this as the measurement from the last step before extending the lines upward. Using the compass between the points on the O.D. introduces the error which is why the length came out shorter than it should have. Good information

The "numbers to space them apart" are arrived by equally dividing the arc segment into 4 equal parts, creating 5 points. A quick down and dirty way to fit a couple of pipes together, especially small like 2", is to nip the 2 opposite edges of a 90 degree pipe end off at about 45 degrees. Don't cut quite all the way to the center line on those cuts. Try on a couple of scrap pieces. A minute of clean up with a 4" grinder will have those pieces fit up and ready to weld!! Of course a 2" hole saw in a still press is also a quick easy way to note a pipe for fit up! Dave

Did you take the length of the outside diameter to do the final cut layout. Like where the line for 1 intersects with the outside diameter of the 3 inch pipe. You added the 1/4 for the outside diameter but u dint measure from the ouside of it but from the inside diameter. I dont know if you understand me.
@XNutayaX7 жыл бұрын
I know that the numbers 1-5 have to be equally spaced, but where did you get the numbers to space them apart? It'd be great if you explained that, my welding class (in high school) has to make saddle cuts to fit two 2" pipes together. Although we have to figure that out ourselves, so I'm trying to look for techniques to help.

He simply used the Compass to automatically space them apart removing the need to measure anything. Your compass is what you are measuring with. If you want number measurements invest in a Pipe Fitters hand book.

hello friend great video , im just curious , it seems to me that you provide a sequence of steps that can be skipped . the step where you cross hare the points seems as though its not necessary as the over head view provides this info . now maybe if it wasnt a 90 degree saddle i could see the need but it seems the over head view generates the needed dimensions. brother im not nocking your work at all im simply attempting to remove confusion from my own mind as i cannot under stand why we would use these extra steps on a t saddle . i laid out a tangent connection using your method and discover i didnt need to use these extra steps , maybe there is something im missing

Hi folk, please, visit www.etubespro.com where you will find a really practical method for saddle templates for tubes/pipes of any size and thickness intersecting any other tubes/pipes at any angle. It works with offsets. It takes only a few minutes to set up the 3D model and see exactly how the connection looks like. Templates are generated in DXF / DWG format and then printed at real scale. This approach is frankly cheaper than any other method. There is no need for any fancy software nor sophisticated equipment to achieve always a perfect fit and welding!.
