To reply to Rick's suggestion directly, let's assume that Dave's balls are still greasy (sorry, couldn't resist!) - getting sand in the old grease will not just fall out with continued motion until the grit falls out, as in Rick's case. That said, there are some really good spray solvents which do a fantastic job of getting crap out of sealed assemblies like this. Loctite do one (though I can't remember the code). You can buy it under the guise of "Nitro spray cleaner" from a model shop, and there's one sold for cleaning electrical contacts that I've harped on about often enough called Servisol 10. You can always tell it's the same stuff because it stinks of lemons. My point is that armed with a can of this stuff you'll most likely to be able to clean out all the grit and old grease after sandblasting, then do as Rick suggests and re-grease.

This, as a side effect, cleaned the rust off the balls and off the inside of the track, which were also rusty on my car's seat tracks. Paint, making a halfhearted effort not to deliberately paint the inside of the track. Lubricate the interior with synthetic grease. That was that. They move like new, probably better. -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
