Never been satisfied with drilling holes in a bench and bolting a press down. Once installed most presses never move again. Always intrigued with the possibility of a quick change system that gives more bench room if needed. Here's what I came up with, two rails of extruded aluminum recessed into the bench top that presses get mounted to. Composite bases are attached to each loader and accessory. Rail allows press to slide up and down the bench, then simply lock it in place by tightening bolts. Next step will be a stock and forearm rest that attaches to the same rail system for cleaning guns.
