Hi guys, i've been doing wrought iron work for years with all kinds of scrolls, twistts and etc and when i measure a space for a scroll to fit in i usually take a piece of stiff wire and wrap it around a scroll jig of the size scroll i want to use and then do the same thing on the other end and then straighten the wire out and measure the length of the wire to determine the length of flat bar needed for that size scroll. My question is this, what is the best way to measure a space for the length of flat bar needed to do a scroll for that space end to end, in other words, lets say i have a space 19" tall and i need to put a scroll in that space thats going to stretch the entire 19" space, whats the best way to determine how much flat bar i need to do a scroll thats going to fill up that 19" tall space. I really would appreciate any help because i've been doing it the hard way for so long that its starting to get on my nerves. Thanks guys.
