PVC rod
 

Where can I get rod from for holding rock together?

I used acrylic rod
Search your area for a plastics vendor

Johnston Plastics.

Very cheap for 3/8" rod.

laird plastics is probably in your area too

Thanks... Yeah acrylic is what I meant, but my brain cells hadn't recovered properly to think of big words like that!
Yeah I found Johnston's, but they will probs be closed tomorrow. I'll phone anyway. Thanks....
