Drilling live rock?
 

what i would like to do is drill a hole through the center of some live rock
run pvc through the center and make a base so i can get possitions impossible with out support
any tips to drilling/experiences ?

Masonary bit, but don't use PVC but 3/8" or 1/4" acrylic rod. You won't have much success drilling live rock wth a 3/4" bit without cracking the rock, so use the smaller acrylic rod and the corresponding drill bit. I also use hydraulic cement to cement the rocks together.

I'll be drilling and building with acrylic rods on the weekend when I set up my new tank. Where do you get hydraulic cement? Is there a brand name I should look for?

Thank You

Clown;

Lol I was going to suggest the acrylic rod and smaller holes, easier to drill like said, and also, much less visible when done.

I used 2 pieces of 1/2 inch acrylic sheets on the bottom of my tank. I then used a drill press to drill holes were 1/2 inch acrylic rod was stuck into and glued. Some of these rods fit into holes in the LR that was drilled with a masonary bit. Seemed to go through my rock quite well. The other rods are just used to support other sections of the LR from underneeth. The whole thing worked well for me.

Where do you buy this acrylic rod?

Industrial Plastics & Paints. They have one in Victoria.

Thanks:biggrin:

i used something called aqua-tite (hydraulic cement)...got it from rona. i used 3/8" acrylic hollow rods and a masonary bit. the guy at the plastic shop told me that the hollow rods were stronger than solid rods.
