The Veritas panel clamp keeps glued-up panels flat. It is easy to use, tightens by hand and is stackable for production work, and you can make double clamp bars of any length to suit your needs.
The specially serrated posts grip the bars, keeping a panel flat under any pressure load without allowing the bars to lift. Bars are made by drilling 3/4" diameter holes in straight stock. 2 x 2s are fine, but 2 x 4s let you stack panels, since there is room for the top of one post and the bottom of another in the same hole. Adjustable O-rings on the posts let you clamp anything from 5/8" to 2" thick without shimming; the clamp pads can be set dead center on the stock. The secret is the balanced tension on the bars: the greater the pressure, the more rigid the bars become. The screw has 5" of travel.
The set includes one head and one tail. Wood is not included.
