Don't bite down too hard Andy, bitten tongues out in cheeks are slow to heal. ;-) Its that stout because it also has to withstand me putting the end of a 4 foot piece of Mahogany 1x12 against it, and a glued on gauge block on the left to precisely locate the board for machining. The touch off gauge, a 3 contact point brass concoction I soldered up a year ago, is screwed & glued to the top face when in gauging position. Currently I am attaching the probe wire to it by hand each time also, which is yet another point of failure I intend to do away with by making it a permanent connection for the duration that the main jig, about 15 lbs of white ash & maple, is secured to the table.
