I finished building our composting bin! Despite the lack of proper tools and any knowledge of what I was doing, it turned out pretty well. I used scrap wood to cut down costs although it was much harder to cut and align. As it turns out, the screen is the most expensive part by far.
I cut all the joints with a hacksaw and a chisel. Which took forever, and the resulting edges were not pretty, but the whole thing went together with the help of screws and a tube of wood glue. I think the end result looks pretty good. It holds all the yard waste we throw into it, which is the main thing. Project: complete!
