I am trying to figure out the lengths of R3 (Spine length), R2 (Center Length), and R1 (Throat Length). I know that D1 equals 6" and that the Center Line Radius is 1.5 x D1. I also know that T1 and T2 are both 9" (I don't think these matter though). Can anyone help me? I'm trying to make an...
The "weights" was a typo from me. My bad. We have been using: W=(10.68*(D-(T/0.875))*(T/0.875))/0.956
T=Nominal Thickness
D= Diameter in Inches
For some reason nobody knows what the .956 is.
I'm sorry if I didn't get a chance to respond. It's been hectic around here.
I know the steel is 5.395" wide coils.
I also know that the nominal weights are:
24 Ga. - .0276"
22 Ga, - .0336"
I would like the formula to be able to be changed for several diameters.
