Quote from: EDGEER on April 07, 2009, 12:22:52 PMThe snap-in bearings work fine. Install a fresh set and you will see. Go to a fabric store and buy a piece of Vinyl to cover your table when not in use and those bearings will last for years. make sure you get a piece that hangs over a couple feet. Hmmm... interesting. Sounds like those snap-in bearings must be made of a material that dries out and become brittle, perhaps even actually dissipating, like styrofoam which actually evaporates, albeit at a much slower rate. Putting a non-porous draping like vinyl, would definitely cut any ambient air flow.So Ed, is that what you or someone you know has experienced? The plastic or whatever composite they use for those bearings are akin to styrofoam or even saran wrap, which most people don't realize as very low volatility "solids"? Otherwise I can't see any other reasons for a vinyl wrap that would shut off any convection draft or ambient air flow at the bearings....
