I was is shrink while bending a kick the same as an offset or would it be half? This has been on my brain all day. Does anyone know the shrink per inch of kick or degree of kick in a table form thanks.

Offset Shrink Table
Angle of Offset Bends

10°
1/16" = .063" shrink per inch of offset


22½°
3/16" = .188" shrink per inch of offset


30°
1/4" = .250" shrink per inch of offset


45°

3/8" = .375" shrink per inch of offset


60°
1/2" = .500" shrink per inch of offset

480Sparky,
Do you know if these shrink values are the same for all radius (radii'?) of bends?

That's a nice list BTW.

Determining shrink values for kicked 90s is the same as figuring for offsets. To find the shrink you must know the angle of the kick and put the center of that bend at the correct spot off the back edge of the 90. I've noticed most people just throw it in the bender and go when kicking 90s. This works fine until you need to do something that requires some precision. You could always bend it long and cut it to length but that's grade A hack

Yeah that sucks. I've been known to take the bottom plate screws out and bunch the studs together to slide a long piece in.

The worst is when the framers don't have enough sense to put the factory holes evenly and at a reasonable height.
