Oilmanmojo: As I awoke the medical motto "First Do No Harm", came to mind along with the following;
An alternate route is to apply feather-weight damping compounds developed by GE as mentioned in earlier postings , uncaping the bearing tube, filling the inner space and then recaping.
Or, a complete revision using carbon fiber tubes for the bearing and tone arm (Tks for the idea & materal). As for the tone arm ,the method for internal damping slightly differs: Prior to filling the arm tube a teflon tubeing is centered for the passage of the phono wires(w/exits front & back ) ,light-weight dampner leveled into 70-80% of the arm tube space, back to front. The challenge is of course end cap hardware and the VTA screw shaft, should the design be manitained.
The effective mass of the arm will change ,the "geometry" should be the same. Head-shell weights in different grams will likely be required (ss,lead & brass are options).
Joe Grado mailed his tri-point headshell weights to me years ago. Modified fan weights can be used inconjuction with the Grado Tri-Points, if extra weight is a must. For that, I'll go back to the books for a final answer.
WoodCrafter EJ suggested because the high pressured bearing manifold expells air mixed w/ oil & water vapors , wood is not a first choice for the bearing tube ; all wood swells in time. Filling the factory tube or a carbon redo are options . For the arm tube anything goes, metal, wood or carbon ... Of course, the "math" is important, enought brain goo for now. All the best.
