Go ahead and glue the pancakes together. I clamped mine all together in one big stack. The Liquid Nails should be enough to hold them together. As I mentioned earlier, using 1/2″ plywood to get a perfect 1″ thick pancake is optional–you’ll have some leftovers from the 3/8″, and you can either leave them seperate or glue two together to make pancakes. On Swing-X I just left the 3/8″ pieces alone, and used them as is a lot–just having little pieces of wood for whatever was a nice thing. Update: the Liquid Nails will NOT be enough, after a few uses. You might have to get some 3/4″ screws or nails to keep ’em together.
