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 excel that will allow me to change the diameter and CLR and give me R3, R2, and R1.

"Length" I assume you mean circumference?

So L= Pi x (2x R1,2 or 3) x 90/360

Where your angle is 90 degrees.

Bless your for trying. If you have a contact for sheet metal supplier or a contractor go visit them and see what is sold and installed in your area. I tried the same thing, then reality slapped me the face.
