hey mike, pretty easy but i did solder the little tack on the body for the cap to slide into....i suppose you can use a small screw or something
My pipe is pvc with threads on both ends. I was actually thinking or dremeling out the final threads on the top end so that the "cap" could be unscrewed slightly (i.e. threads mesh) for transport, and then screw it tighter past the threads for usage.
I'm not opposed to soldering but I've only done it twice and I'm not very good at it!
