@Brian has been working on various 3D printed ideas to make using the Collet Nut Crown Wrench easier to do. His latest invention is quite promising … it is basically a holder for the wrench that get a little better grip on the nut while providing a more hand friendly handle.
Place the torque wrench on the flats of the spindle, slip the wrench on the nut and brace the wrench handle against the Z support plate … the handle definitely makes it easier to do.
Alas, we still wait deliver of new wrenches to replace the existing ones, but this does help even with the current wear on the existing wrench prongs.
Separately, a lower profile wrench is still in the works to make it easier to install/remove large diameter mills such as the table surfacing bit and the large V-bit with replaceable carbide cutters. Progress has been hindered by both available volunteer time and the degree of technical challenge.
