I just built a shed to store dive gear and everything else that would normally go in a garage except I don't have a garage. I want to build a stand so I can walk the doubles from my vehicle and just sit down on the bench, doff them, and leave them there upright. So the stand is basically a bench long enough for two sets of doubles side by side, with an upright support extending horizontally across the bench to lean the tanks against (rather than against the wall). Building such a stand does not seem difficult--there are stands kind of like that at Florida springs dive sites--but before I re-invent the wheel I thought I would ask if anyone has a design they might share?
