I built this workbench out of scraps from other projects I had. The MDF for the top was left over from the router table extension. cupla new 2×4’s and some old ones, even made my own 1’ ply for the shelf from some old 1/2” ply that was in the treehouse we tore down this year. That wood has seen life in 4 projects now! started out as concrete forms, moved to temp decking, then the treehouse and now a workbench.
I used my Kerfmaker to notch out the 2×4’s so I could make the top kind of a torsion box, it also lets me use the edge of the MDF topper to hang clamps on instead of a full frame around the outside edge or to clamp down to when I have a work piece on it Picked up some plastic bins from HD to use as “drawers” to hold all my smaller power tools and some hand tool, also a rag box, and a bin full of fasteners.
I cleared the existing shelf above and the cupboards above for storage as well, still working on configuring that space for working rather than just junk storage.
