This nailing jig is used to assemble 10 frames in the time it takes for two or three individually. Line up 10 side bars, glue and nail on the top bars, then flip it over and glue and nail bottom bars. Put in some beautiful Walter T Kelley wax foundation, hold it in place with bobby pins and get on with your life. You've got too much going on to waste time getting frames ready.
