Sorry, this item sold. Have SimpliedWoodCraft make something just for you, or try these other items:
The front edge has a 3/16” step to allow either conventional use, or standing the press on the front end (see picture) to align material both on a table top and against the side rail at the same time. The knobs will clear, thus allowing them to then be easily spun down holding everything firmly in place. This also leaves 3/16” of paper edge exposed and ready for glue, rubber cement, etc. Overall dimensions: 10” wide x 5-1/2” deep x 4” high (top of bolt). A pair of plated 5/16-18 carriage bolts are glued & pressed in. The clamp bar is pressed by using a pair of polypropylene 3 arm knobs with brass thread inserts for ease in clamping down tightly.
Special sizes, materials, or knobs will be quoted on request.
