Thank you  for all the nice comments..

Hi Bruce, we went to Natural Expressions in Gilbert, Az a few weeks ago. That is like one of the biggest rock shops in the world. Fred had rocks from all over the world. They make a lot of inlays with diamond grinders that take rocks. down to  inlay powder. They have a rock saws with blades up to 36" diameter and they use diesel  fuel for a lubricant!!

Hi Rob. Those zebra  rocks are super cool!!!! There is not very much space for two jets that would have to split on either side. This is compact and does a nice job of delivering the coolant.

Cheers,Jim
