Sorry, I've been leaving ya'll hanging. Still working on the thing, and will update the little more I done so far with a couple more photos, maybe tonight.
The framing really didn't seem that heavy; kiln dried white-wood stud is actually light. Now if it was yellow pine studs...
When I added the plywood, that when it got HEAVY
. Got tired of dragging it in and out of the garage at the end of the day and it been sitting on the driveway under a tarp in-between work sessions. A furniture dolly will be a necessarity to get into the house without breaking my back.
I think I'm a couple inches short of 5 feet, but a 90 gal at 5 feet length on top and a 40 gal at 4 feet length on bottom could have worked better. No 90 gallons included in the $-a-gallon sale that started this thing.
