I don’t know if it’s just Colorado stores, or what, but there are some clearance blue pine boards for really cheap at home Depot. The 1x4x8’ are $1.22 ea. And there is some prefinished shiplap blue stuff that’s $17/6"x8’x6pk.
I’m buying a bunch and making shop fixtures out of it.
I’m pretty sure it’s not beetle kill, because the stain is everywhere on the outside and nowhere inside, but that might make even better for cnc projects.
