Pond Boss Forums INTRO Questions & Observations What pier diameter for dock

I'll be renting a vibrator. As far as attachments, I've never used brackets before, I've always just used j-bolts. I have no objection to brackets but I don't see it doing much for me and it seems like just one more thing to rust out. I was just figuring on a single j-bolt per pier, centered, then I'd just bolt a treated 4X4 or 6X6 to the top, letting the end extend just past the last pier so I can attach the end board directly to the wood, then string joists between them.

My builder recommended some outrageous size of pier because he said a tornado picked up his dock and threw it to the other size of the pond which, for some reason, he blamed on under sized piers. Not sure a dock can be made tornado proof! Apparently, his was really built up, he said it even had a wet bar!
