I got the coupler at Home Depot, in the plumbing section. It's for joining two pieces of pipe together.Good luck with your project!
Oh, almost missed part of the question.It's basically a double hose clamp, so it takes a socket on either end to tighten.
Good questions!I'm not sure how much the barrel weighs now, but it's heavy enough not to tip even with that huge umbrella. It is movable; I just push on one side at a time, and shift it from one place to another.So far the wood has held up, and we're still using/enjoying it. I think the char helps. I have no idea how long it'll last, but I figure that when it finally gives up the ghost, I'll get another barrel and (carefully!) transfer the concrete mass to the new barrel.
