Tube bending 90 degree MATH

[@Skunkhunt_42]

Good vidyo thanks!

[@yoyoman3386]

How do you calculate the radius if the bender doesn't provide that info?

[@jerryrojas6198]

Thank you, for taking the time and effort. Great video in a simple platform I myself can understand.

I thought you line your mark up with the R?

[@instrumentationvideos7712]

there are multiple places you can line your mark up with, depending on your approach. Most benders have the "0" mark, a 45 mark, a "R" mark, and a "L" mark. each has it's purpose and requires understanding when and how to use those marks.

Could have used milimeters

[@Skunkhunt_42]

I use a aviation mechanics tape measure. Has imperial with decimal and metric

can i apply your formula in 180 degree?

[@instrumentationvideos7712]

the formula for calculating the length of tubing in a bend can be used for any degree of bend 0-360. Take-up calculations for 90 degree bends are much easier to calculate that other non 90 bends, treat a 180 degree bend as two 90 bends and you should be good. If you are trying to calculate takeup for anything else other that 90 degree bends, it will require a bit of trigonometry using sine, cosine, and arc length calculations.
