Okay so how do I work out how to bend this.
I will use rounded up figures to make it easy, and it is in metric.
Making a handle out of 20NB pipe that has a 90 degree bend at either end. Lets say that from outside to outside it needs to be 1000mm long. How do I know where to make the bends in the pipe. How far apart should the two starting lines be from each other?
I do not know the radius of the bender right now, but I can try to measure it. Then what do you do?
If the radius is say 100mm of the bender do you just go 100+100 for the two bends then that would mean make the marks 800mm apart. So 100+800+100 =1000mm. Oh, you would have to subtract 2 x the diameter of the pipe as well.
So then 100-27mmOD pipe (I think it is 27)=73mm
So 1000-73-73= 854 distance to have the two bend marks apart.
That sounds about right to me, it that right?
