When gluing a panel together most people use a row of clamps as the platform to place the wood on top of. This works but it can be MUCH better. The problem is that if after the glue is applied and the pieces are ready to be clamped any repositioning of the clamps will cause the panel to shift. Also, repositioning of the panel might cause the clamps to shift. Sometimes it can be an annoying back and forth process. The goal is to isolate the material movement from the clamp movement. A few PVC pipe platforms will do the trick. Make these and you’ll be wondering why you haven’t made them sooner.
