balls and more balls

Hi all,
A quick seartch of the web finds lots of sources
for tungsten carbide balls, etc.

http://www.hooverprecision.com/tunball.htm

http://www.salemball.com/tung.htm

are a couple of links. I'm certain they want to
sell you a thou or so at a time but they might
send samples if you tell them what you are up to.
:-)

Good luck,

Dave
