ClampZILLA 4-Way Panel Clamps: [ Ссылка ]
Woodworkers have been trying different ways to keep boards flat while gluing panels since glue was invented. Most clamps introduce a bow in the panel because they are clamping from one side (the one with the bar). Even the best designs pull a certain amount and most could be used to make boomerangs. Savvy woodworkers try to overcome this by alternating clamps top and bottom, but getting the pressure perfectly even never happens. Woodpeckers ClampZILLA 4-Way Panel Clamp places a bar on both sides of your stock with centering devices that direct the pressure to the exact center of your stock.
