outside radius

[phoxeoy]

Does anybody know a formula or ralation I can use that would figure out
the outside bend radius. I know it would be better to just do this in
sheetmetal and use thicken but I can't. I have to model in a strange
way, It's a long story. Anyway I have a inside radius of .50 and a
k-factor of .318310 / y-factor of .500. When I do it in sheetmetal I
get a outside radius of .880. I can't seem to recreate that with any
calculation. HELP!

Never mind. I feel stupid, I get my answer simply be taking the inside
plus the thickness whic gives me the same results as thicken. I'm
thinking in reverse, flat pattern. Prime example of over thinking.
