This video is for use with INTC 2333 course at BRazosport College. This video demonstrates how to calculate total length of tubing required for the project and performing the bends to produce a 45/45 offset that gives a 2 inch rise.
Excellent presentation.
t my offsets were always a little out and i wasnt sure why until i watched your video , wasnt subtracting the bend gain . thanks !
Excellent explanation But how i spsefic the degree bend
Para hacer una balloneta de 45 grados se multiplica la longitud que vamos a librar porque nos obstruye el paso suponiendo que la vigueta es de 20 cm. 20cm.X 1.414 y te da el resultado de tu ING que vas a ocupar.
Why is the calculation so complicated?
c=ax1.414=2x1.414=2.828
It is common to just multiply a by 1.414. However, this video helps to understand where that comes from and allows you to make calculations for any angle, not just 45s. 1.414 x a only works for 45s.
I can't follow, each time I try an offset of 2" (1/4" tubing) it ends up being like 2 5/16". Frustration is high!!! I can bend electrical EMT in my sleep but this is far more complicated it seems.
With your straight piece of tube, mark your first bend, then from that mark, measure 2 13/16s and mark. Now you can put your marks on the zero of the bender or on the 45 on the bender (if it has it). If you bend on 0 for the first bend, you have to bend on zero for the second, same with the 45. Bend to 45 degrees and check your tube with the 45 side of an adjustable square. Bend to 45 on second mark and check the angle. Now you will have a 2" offset.
The travel is 2 13/16 but what about the loss ( 13/16) do I have to mark my tube for the loss ?
