Alright as promised, the initial pictures!
The basic idea came from this, except I had an almost 4x8 sheet of 3/4" plywood that I'd rescued from a dumpster, and 2x2's are really cheap, as I work next door to a lumber place. Keep in mind that I have literally nothing for woodwork experience and only simple tools.
Pieces for the framework of it are cut. Like my sawhorse?
Basic framework from the back, front and top are on.
View from front, had gotten part way through drilling first of 4 holes for door opening corners when last battery had had enough.
Things I didn't think of in advance: Get a pencil, make sure of having correct bit for screws, measure twice, linear available amount of a 2"x2"x4' and the length of pieces needed. It's awkward cutting off less than an inch with a cordless trim saw. For a really big or pretty project like this, a level surface that is not at stooping height would be nice. I refuse to check but I'm pretty sure that nothing is square. I know the front piece is, as I checked corner to corner measurements, but I think I'll still pick up a piece of 1/2" styrofoam for under tank tomorrow. As well as ask my brother in law for some hardwood shims.
Hmm, too long. Anyhow, until tomorrow evening...
