It's a confusing photo, Rolling clamp rack built on a yard sale cart, weight rack, and lumber rack in the back ground. All build from scrap wood (and the weight rack shows it), construction dumpsters, and salvaged crates.
Restored 4" jointer on scrap wood and salvage flooring deck. The 2X4s that make the frame under the plywood are much crappier than what you're selling. They only have to be true on 2 sides, then a 60 grit belt on a sander to "fine tune".
Old cabinet with scrap wood racks ... and a fine assortment of truing tools. All those dividers cut from warped & twisted dunnage.
Shave horse, salvaged beams
Wood cost on all of this is pretty much just sweat equity. My friends call my shop OPG- Other Peoples Garbage. Putty and paint, makes it look like what it ain't.
