I put treated wood sideways touching concrete to stop any moisture traveling.
I measured my desired finial height, subtracted my 2×4 and table top so I could snap a line down the whole wall. Ran the uglier 2×4’s as a toeboard so the top was easy to mount.
I built in my DeWalt radial arm saw. It barely fits under my overhead lumber storage.
The workbench is built at two heights. The left is for tool work (drill press, band saw, grinder, sander) as these tools have an elevated work height already. The right section is for stock handling. The RAS and compound miter are set up here and can handle 12’ stock without bumping the far wall.
Overall the left is 12’ long
30" and the right is 10' long 36”. Both are 24” deep and have a 21” shelf below. I plan on finishing the tops with hardboard, routing the edges and putting some cheap MDF moulding on to protect the walls. On the lower section I will probably put a solid toe board so it doesn’t turn into a mouse haven.
