Once upon a time, before a terrible lapse in judgment, I owned a Shopcart which did all these things you read in the title. The need for such a device has returned, and building one seemed the better option over the $1200 to purchase. The one feature the Shopcart has which I did not include was a hydraulic jack for raising the deck a pump at a time to keep it at the tablesaw height. My one improvement was the placement of fixed casters in the center. You can pivot this cart in a circle with one hand, and when you roll it, it tracks. (I opted for two fixed and two swivel casters on my early Shopcart—far better than four swivels.)
Height to top of deck: 34.5
Deck: 46×71; 2.75 thick
Deck lip: 5.5 high
Hardware: 2 floor locks (Grainger); 6 casters (2 fixed; 4 swivel) (Grainger); 3 HD door butt hinges (exterior door) (Habitat ReStore); 48” piano hinge (Hardware Supplier).
Notes: Deck is a torsion box with 11/16 webbing, pine and cedar (for lightness). Skin is 1/8 ply. 6 each 3/8” teenuts to receive lip bolts, installed during construction. Interior reinforcement for attachment of hinge board likewise.
Deck locking structure is 2.5” maple, pocket screwed. Pieces are identical for simplicity. I am indebted to J D Grinnell for the design of the locking device. It is simple, elegant, and secure.
Things I’d do differently: I bought cheap floor locks and they’re an annoyance to operate. They are important to the function and safety of the cart, so they’ll likely get changed out.
Silliness: When I saw the torsion box complete but for the top skin, I couldn’t resist it—I dug out some 3/4” steel balls I had stashed away and placed them in various compartments (they’re about 6” square). Now when you tilt the deck, there’s this lovely friendly music that accompanies the act.
