Note about K-Factors... source: anonymous commenter
"K factor we learned in die design school that if your bend radius is less than two times the thickness of stock, use a K factor of 0.33 times thickness. If the radius is two to four times thickness use a K factor of 0.4 times thickness. Anything greater then that we would use .5 times thickness."
