MrFixr55,
My woodworking skills suck, they suck because when I took woodshop in HS I was afraid of getting my fingers cut off, and I was like that Tweak kid on South Park complete with coffee. And between now and than I didn't get much practice in until I got some decent tools.
Nobody is Bob Vila at first. I got better playing around with hanging shelves and stuff and the important thing is I was seeing improvement.

The speaker I used had a lot of crud and crust inside the speaker grill, the whole thing being glued together. This stuff rattled around, and there was a hairline crack straight across the plastic grill that buzzed. Plus all that was buried behind another sound muffling layer.....the china "Philco" speaker cloth.

You reminded me of this solar off-grid type book from TaB books from 1982 or around there.
They talked about different battery bankes and the kinds of inverters you can run stuff off.
It mentioned rotary inverters, vibrator inverters, square wave slidstte inverters and the sine wave solidstate inverters.
It said having a sine wave inverter wasn't the end of problems, that some radios would work just fine on a cheap square wave but crackled like H**l on an expensive sine wave inverter. And vise versa
It mentioned a "Topaz" inverter which was a pretty no nonsense piece of gear.
