Aurios under JC1 monoblock's?

Perfectionist - the rubber pieces may actually be an interesting discovery for you. One thing about rubber though from what I have learned, is that the durometer rating could play a factor. Products like sorbothane or the rubber-based dampening products you can find at McMaster-Carr work differently based on durometer rating and the load placed on them. I recently had a friend test the rubberized material used in the HRS damping plates and he found it to have a durometer rating of 40. So he sent me some plain old rubber squares with the same rating to see how it might work on various components (top covers and underneath). I'm in the process of trying them out now so we'll see what happens.

Tvad - I'm not sure if this is going to take you where you need to go, but:

If it is not a direct link, then type in "carbide balls" (sans parentheses) in the search box. When the navigation tree pops up on the left select Tungsten Carbide Balls, then Precision Grade 25..., then you size.

I bought my 5/8" TC balls from Hoover Precision.

Not sure why my links are not working properly, test...
