I added another little upgrade. A Grade 8 clamping system that holds the torque multiplier steady as a rock (it had been torquing over a bit when you cranked the handle). The clamping system goes all the way through the three stacked 2 x 10's and the torque multiplier's arm pushes down while the clamp pulls up which results in no movement. Of course it disassembles quickly for easy transport.
Mucho Coolo.
