Hi Watson -
I may be Deb Tucker’s #1 fan, and I heartily recommend the Wing Clipper for your project. However, I also understand budget constraints. I recommend you print Deb’s Wing Clipper instructions, found here:

Trimming Flying Geese units and see if you have a ruler that will work. If not, you could use some glow line tape on one of your rulers to make the opposing 45* lines that cross a quarter inch from the edge of the ruler. My solution is not as elegant and easy as the Wing Clipper, but I have used it for a couple of sizes of FG units and had good success. Hope it helps.

ETA: Deb also has a YouTube channel and has at least one tutorial for each of her tools. Her explanation for making the “no waste” FG is a good one. She also gives some troubleshooting tips in either the FG video or another one to help with some of the common errors in making FG units.
