Ok like if I have 1/4" tubing and wanna bend it into a 90 to have it fit on a rear bag cross member,and it needs to be say lik 47" long,i have to take the thickness (1/4" thick which 1/4"+1/4"=1/2" for every 90 degrees add the thickness metal by 2 times) so i would have to cut the tubing out 47 1/2" inches out right?? i know this works for sheet metal of the various thickness of up to a 1/16",and how do i calculate for tubing??????

lemme re-write this 1/4" wall thickness 2" round tubing.47" long from notch to notch for example (1/4" + 1/4"=1/2) so 47 1/2" total right????

i would just get extra tubing and then bend it and cut it to size, easier then cutting it too short.

you would have to measure straight across from where you want the crossmember to weld to on each notch, then measure from the center of the imaginary straight crossmember to the center of the angle.
you could then take 1/2 of the 47" and get23.5, with these two numbers you will be able to figure out the perimeter of a triangle, once you have that multiply it by 2, and you will get the length of tubing you need to cut

ok,so from notch to notch its 47",find the center.so half of 47 is 23.5.23.5 on the left side and 23.5 on the right and multiply 23.5 by 2 to find the total tubing length??? i just used 90 degrees and 47" for an example,see i wanting to get bends like this but their has to be a mathematicial equation to it right?
