I roughed one of these out over the weekend and it feels really smooth and solid, no play in the head and it stays parallel when moved. And of course it sounds better with the carbon fiber arms!

It may be over-thinking, but it's very easy and inexpensive to take care of the slop in the lazy susan. I bought the tightest 12" lazy susan I found, but it still had some play. I mentioned this to my dad, who's a mechanical engineer, and he told me this simple way to fix the problem with a 2" lazy susan, a bolt, a nut, and washers. Like John, I made a modified Williams jig with the box underneath the 12" lazy susan. On mine there is a hole through the center of the plywood under the lazy susan and also the center of the piece above the lazy susan, so the bolt can go through both holes while the assembly rotates around it. The holes are oversized relative to the bolt, so they don't have to be perfectly centered. The 2" lazy susan goes on top of the plywood above the 12" lazy susan. I put washers on top and bottom of the whole assembly and put the bolt through the whole thing. The nut then needs to be tightened enough to hold everything, but not so tight to inhibit rotation. It's extremely stable with insignificant play after this.
