The AC draws a lot of moisture out of the air. That is the drain for it and has been mentioned, its plugged somewhere downstream.
Don't plug it, otherwise your coil will be sitting in a puddle of water and drip down into the furnace below it. That curved dip below the tee probably has a bunch...
The edging can be iron on banding or solid wood. In fact, solid wood will increase the load capacity of the shelf and prevent it from bowing. You can glue it on and use a few pin nails to hold while it dries. Just keep the top edge of the wood level with the top edge of the plywood to keep it...
That looks like a nice design for a bookshelf.
Cherry, red or white oak, walnut. I buy the lumber rough and machine it down to suit my needs. But you need the tools (jointer, planer) to do that.
Buying 1x lumber at places like HD/Lowes is very expensive.
I wouldn't shy away from plywood. You...
I think for that much difference I would go asphalt.
Yes you have to reseal it periodically but it will still cost less in the long run.

I wouldn't glue the flooring to the plywood though. Wood needs to expand and contract across the grain with changes in humidity. You could glue the two sheets together, but screws would be...
