I have a store called Bearings & Drives located in my city. I am not really sure what this type of business is called.
On Audio Asylum I made mention that Timkens don't seem to like contact with Maple. This has proven to be an erroneous conclusion.
One thing to note about the Timkens for the uninitiated is that they form a stationary footer and do not move at all as you would assume a bearing would do. Also, if you try this be sure you know that the Timken part numbers are purposely mismatched. The bearing vendor may point this out, but the part numbers mentioned are correct.
One last thing, I like using the Timkens in conjunction with small DH Cones. They provide more "snap" to the presentation.
This tweak was pointed out to me by Ric Cummins of Room Lens fame. For use under electronics he recommends placing Timken assembly atop a granite slab and 2"X2" plexiglas/posterboard/plexiglas footers. I haven't tried this yet myself.
The Timken assembly photo I posted on Audio Asylum includes O-rings which I added to the mix.
