Use a Shop Vac to Repair Cracked Wood

If you have ever tried to get glue into a cracked board you will know it is no easy task. You usually end up just getting glue on the outside edges and it could easily crack open again. Using a shop vacuum on one side while applying glue on the other will bring the glue all the way through the crack. After that just clamp it until the glue dries.
