pete Report post Posted August 16, 2017 I have bought a few metal 12" rulers over the years and cover the backs with clear tape to keep them clean. I also measure the rulers widths and write the measurements on the back with a sharpie. They are all different but handy to have a known width. The 36" aluminum ruler is a Johnson and Level Tool Co part # js236-0554. It is 1 1/8 wide and I can scribe a 36" line on each side on my tracing film to get a perfect border line(s) as I use 3/16ths borders. for 1 1/2" belts- the width I am most asked to make. got it at Springfield.
