My bench was occupied by a large table top and on top of that were the two cabinet doors I installed glass in for a client. No clamping going on there. My CNC was in use working on an inlay project. No clamping going on there, either. That same inlay project required some panels to be laminated. What to do? Clamp up the "sandwich" on the slider wagon using the cam clamps and a couple of Bow-clamps. Whatever works...
