Gluing up wide panels can be a chore. This is especially true if the panel is wider than your workbench because it’s almost impossible to stand the clamps up while positioning your workpieces. To avoid this hassle, I came up with the solution you see here.
I made two clamp supports by mounting a piece of 2x4 lumber to a hardboard base. Notches cut along the top edge of the supports fit the clamp bars perfectly. Now, gluing up a large panel is as simple as dropping the clamps into the notches and placing the panel workpieces in place.
