I discovered a second process for small glue joint surfaces (approximately pencil thin) and yet strong as hell. It started by using hot glue gun. I could see the temp. was not hot enough so I got out the digital thermometer and started experimenting. Using an old clothes iron and a glue gun, coat the surfaces to be glued with the glue gun and set them aside, now with the Iron pre set to 400~430 degrees F remelt the surfaces to be joined. Quickly join with as much pressure as you can apply by hand for a good glue line, hold for several seconds while blowing on it to assist cooling. Try it, experimenting, science, and woodworking is so much fun.
