Even more on the Mathematics of the Offset Bend

I have again revised the article and calculator in the mathematics of the offset bend, and did some bends to verify the calculator. I also added a calculation for the straight pipe length that is the straight piece of pipe between the two offset bends. Oh yes, many a time, I have made the first bend to steep only to find that I couldn’t make the second bend. Then I would have to take degrees out of the first bend and wrestle the pipe around trying to get the correct offset height. Anyway, the offset calculations appear to be more accurate than the Tables supplied with various benders.
