Step 6Substitute ball joint
What I really wanted was a ball-joint, like the one the Gold Touch comes with. Unfortunately, I couldn't make that one work, and industrial ball-joints from places like McMaster-Carr are too expensive. So, I made my own 3-degree-of-freedom joint from outdoor lightbulb fixtures.
Take two light fixtures, remove the internal light bulb mount, and cut off the housing around that mount. I used a hacksaw, cut the housing off, and then filed any remaining material leaving a flat surface. Drill holes and bolt two of these together with the adjusters 90 degrees out of phase. Their screw mounts give you freedom of movement in the roll direction on both sides of the keyboard, one toothed adjuster gives pitch, and the other gives jaw freedom of movement.
Since I already had the 2x4's mounted to my keyboard, I cut them apart and screwed on pieces of plywood to attach the light fixture's screw mounts.
I held my hands at neutral, had someone measure their position, and then adjusted the keyboard into that position.
