joining rocks with rods... what type is good?

[kwirky]

i used plastic ties, and it's butt ugly. if you want to take the time to drill it, I'd do that. Or just build a rack to set the rocks on top of, letting gravity do it's thing.

But a note, I don't think solid rods will be strong enough, I think you will need something like PVC. I used 1/2" PVC to hold up my rocks with enough strength. Most people online who drilled through their rocks used the same.

I didn't drill mine, because of the drill and bit required to make 1/2" holes in rock. I think I may down the road make a "pedestal" like structure out of PVC and elbows, and just set the rocks on top.

One piece of advice I have to give, is you can't really make your structure, then buy your rocks. You'd be going through hell trying to find rocks that will work perfect on your structure.

If I was to do it again, and had the tools, I would drill for 1/2" PVC. It would make me feel safe that it won't snap like acrylic rods. Thick enough acrylic rods to support the rock would be EXPENSIVE and not much stronger than slightly thicker PVC pipe. And I would buy my rocks, then build the structure during the curing process, having the rocks handy to make it all jive together.
