I didn't like the TP that came with the machine, it was bulky, the compound slide handle binds and is hard to turn, almost all of the tools were too high even in the lowest position. So I got this Phase II BXA wedge to use. I got a 3x3x2 block of 6061, drilled a 5/8" hole offset to match the BXA, and machined a 1.75" recess 0.003" deep around the bolt hole so that the perimeter will be grabbing instead of the center. Then I got a 16mm x 1.5mm x 180mm 8.8 bolt, turned off the head and turned the half of the shaft to fix the 5/8" hole, turned the very end small enough to fit into the T-slot and treaded the end to fit the a 7/16 x 14 T-nut.
