This Jig allows you to assemble 10 frames at a time of all three sizes.
You stack 10 end bars in each side between the follower board and the side. Run a bead of glue over the end bars. Insert the top bars and nail. Turn the Jig over and glue and nail the bottom bars. Keeps frames square when assembling. All 10-Frames will easily slide out with the masonite follower boards. Complete with instructions.
