Floating a cruise ship in a bucket of water | Physics Forums

Producing the spherical shell by grinding in the cup is an advantage and a disadvantage with glass. The problem is that glass tends to grind metals and other glass when water is present. Going back to optical measurements with a glass cup and ball, it seems the friction coefficient of glass on glass in a water saturated atmosphere is very close ...

I think they'll be OK. The seats didn't really have a truly spherical surface to start with as they were probably cold forged. It might be necessary to grind in 0.020" to 0.030" to get full contact with the ball, not worth the work. I think some material was removed from the ball during grinding, as well, but I won't be using that ball.
