Ever since I saw this written up on Mark's page, I thought it was one of the most forehead-slapping moments I've ever had, as in "why didn't I think of that?". After trying to figure out how to shape and pre-wet flanges or angles upside-down inside the top of the tank to make sure the closure panel was fully seated and that the seam was wetted out, Mark's how-to-do-it sequence answered that question perfectly. In case you haven't seen it, go here and scroll down to the tank construction: http://www.n56ml.com/900hour/ , with the key photo being this one: http://www.n56ml.com/900hour/100717014.jpg .Duct tape, spring clips, and a piece of metal angle. Couldn't be simpler. Oscar Zuniga Medford, OR
