I have finished the oil dampening system modifications for the new arm designed. In the spirit of using the existing equipment, i mounted the swing out dampening trough under the airbearing spindle. I then mounted a tapered pin on the armwand clamp and it protrudes into the trough. I have filled the trough with a highly viscous oil (heavier than motor oil) that my lubes plant produces. The degree of dampening is set by the depth of the fluid in the trough. I can adjust this by a displacer which goes into the trough. I will get some pics of the finished design.
As far as performance, the dampening system works well in that i can adjust the level of dampening very easily and while the record is playing. I found that too much dampening will mute the delicate highs but since it is easy to adjust, i can fine tune it easily. I usually have just the tip of the pin in the fluid unless i have a wavy record or have a record that is difficult to track due to intensity. The design is very similar to the oil dampening system on the walker table but alas it is not nearly as refined.
I now feel i have a table that can deliver everything that is in the grooves. I recently upgraded the cartridge to the universe and feel the system can handle this great cartridge. I am still fine tuning the vtf and vta but I have been tremedously please with the results of the table, arm and now top flight cartridge. I still need to upgrade my phono stage (maybe santa will be good to me:~) I have found myself listening to records finding details that just were not there a few months ago. Some of the delicate bells on Ricky Lee Jones debut album, the presence and sound stage listening to Karajan (1812 overture), the absolute silence required in the system before the flutes start playing the intro into Bolero(never could understand why the record was so hard to listen to until I got this system optimized, and I could go on about the quality of the sound. I truly think the stiffness of the carbon fiber arm clamped to the air bearing spindle was one of the keys to getting the system performance up. Also, the upgrade to silver tonearm wires made a tremedous difference. The vta adjustment is nice, but i do not think it had as significant impact as the stiffness of the armwand system. I also really like the dampening system since it now longer swings above the record. That is a small issue but now i do not have to worry about it as i am changing LPs.
Thanks for all of the input and ideas from various members of the forum especially Crem1 and Piedpiper (2 other maplenuts!). I have really enjoyed listening to how others have improved this line of table.
