The tone arm pods are machined from solid brass. Looking in the remnant pile at a metal supply warehouse I found a 4 foot cylinder of brass 3 3/4" in diameter. The pods in the picture are 5" high. These pods are for surface-mount tonearms like Schroeder (pictured), Triplanar, and ET 2.5. These pods will not work for central pillar arms like Rega/OL, Moerch or the new airbearing Conductor.

For the central pillar arms I purchased two surplus hardwood armboards (monkeywood and purpleheart) from Teres Audio. Teres installed one of their VTA adapters in the purpleheart armboard. The armboard is 1 1/4" thick, seven inches long and comes with a predrilled threaded hole (3/8"-16) on the bottom 1 3/4" from the end opposite the VTA adapter. I need to have machined two more columns of brass from my cylinder, each column 3 3/4" high with a 3/8-16 hole tapped in the center. Screw a brass stud into the pod and then thread the armboard onto the pod and you have a wooden armboard securely attached to the top of the brass pod with over 3" of overhang. Different inserts can be purchased for the Teres VTA Adapter: 22mm for Rega/OL, 20mm for Moerch, and 17mm for the Conductor air bearing. Or I can drill any size mounting hole needed in the monkeywood armboard. The Teres VTA adapter will give me on-the-fly VTA adjustment for any central pillar tonearm. Since I have a Moerch DP-6 with 12" blue dot arm, I am hoping to get these new brass pods machined in the next month or so.

When the pods are done I will post a picture of the table with the DP-6, the Schroeder Reference, and a VPI 12.5. I also have three identical AT OC9/II cartridges. I will now be able to do A-B-C comparisons with tonearms with the only variable being the arms themselves (assuming the wood base does not sound that much different from the all brass pod).
