  • Garage bin shelving unit

    Garage bin shelving unit

    Give garage bins a visible, accessible home

    This fixed plywood shelving unit provides three open storage bays for totes, baskets and folded shop supplies. Full-height sides and a full back enclose the storage, while wood cleats support the shelf ends and glued front/rear stiffeners help the shelf decks resist bending. The fourth deck forms the top; leave it clear rather than using it for overhead storage.

    The unit is 48 inches wide, 24 inches deep including its back, and 72 inches high. It stands on the floor and must be secured to wood wall studs with two compatible anti-tip restraints before use. The wall connection prevents tipping; the floor supports the cabinet’s weight. This is a dry, indoor storage prototype with no assigned load rating.

    Measure your bins and installation space

    • Each of the three front openings is 46 1/2 inches wide and 18 1/2 inches high beneath the front stiffener. The shelf deck is 23 1/2 inches deep. There is more height behind the front rail, but the bin still has to pass through that opening.
    • As a size example, two bins each up to 22 inches wide × 22 1/2 inches deep × 17 1/2 inches high leave nominal handling space. Measure the maximum outside size including lid, handles and any latch protrusions. These dimensions describe fit, not an approved bin weight or a particular tote product.
    • Allow space to pull bins straight out, not just room for the cabinet. Locate outlets, garage-door hardware, pipes and switches before choosing a location. Confirm two sound wood studs can be reached by the upper restraints.
    • Check floor level and moisture. Seal panel edges. Do not place unfinished plywood against a damp slab or use this plan outdoors. Solid full-bearing shims can correct a small floor variation; a significantly sloped garage floor needs a separately designed base. Baseboards may create a wall gap that the selected restraint system must accommodate without bending the brackets.

    Cut list

    All dimensions are inches and use actual 3/4-inch side/deck plywood, 1/2-inch backing, 3/4 × 1 1/2-inch 1×2 cleats, 3/4 × 2 1/2-inch 1×3 stiffeners and 1 1/2 × 3 1/2-inch 2×4 stock. Measure your materials before cutting. For a 48-inch outside width, deck length = 48 minus twice the actual side thickness. Stiffener and block length = deck length minus twice the cleat thickness. Cut decks to the dry-fitted opening if your stock differs.

    Material allocation: two full 48 × 96-inch sheets of 3/4-inch plywood and one full sheet of 1/2-inch plywood. From the first thick sheet, crosscut a 72-inch section; rip two 23 1/2-inch-wide sides from it. The remaining approximately 23 7/8 × 48-inch section yields one deck. From the second thick sheet cut three more decks, orienting their 46 1/2-inch dimension across the sheet. The thin sheet yields the 48 × 72-inch back. These layouts allow a nominal 1/8-inch kerf but little extra length for trimming the first sheet; verify usable sheet sizes before committing. The offcuts remain useful for other projects.

    Three 8-foot 1×2 boards yield the eight cleats (three per board, one spare). Four 8-foot 1×3 boards yield the seven stiffeners (two per board, one spare). One 8-foot 2×4 yields the anchor block. Reject badly warped, split or knot-weakened pieces, especially the cleats and anchor block.

    Connection details are schematic. Select anti-tip hardware approved for the illustrated through-bolt and wood-stud attachment.

    Fasteners and restraint hardware

    • Approximately 80 #8 × 1 1/4-inch wood screws: 48 cleat-to-side screws (six per cleat) and 32 deck-to-cleat screws (four per shelf end). The 1 1/4-inch cleat screw passes through the 3/4-inch cleat into 1/2 inch of the side panel; test in scrap so points do not emerge.
    • Forty #8 × 1 3/4-inch wood screws: five per stiffener and five for the upper rear block, driven through the deck from above. Glue the full contact edges/faces before assembly. These screws draw the parts together; the narrow glued stiffener edge needs continuous contact without gaps.
    • Approximately 55 #8 × 1-inch screws for the back, plus wood glue. Pilot holes are especially important where screws enter the 3/4-inch side-panel edges. Keep every screw centered in the material it enters. Do not substitute drywall screws.
    • Two furniture anti-tip angle-bracket assemblies with a manufacturer-approved through-bolt attachment to the cabinet top and screw attachment to wood studs. The upper rear block supplies solid backing under the 3/4-inch top. Choose bracket feet that reach this block and permit fastener holes away from its edges; do not drill or modify the bracket unless permitted.
    • Cabinet-side bolts, large washers and locking nuts must pass through the bracket, 3/4-inch top and 1 1/2-inch block: 2 1/4 inches of wood plus hardware. Select diameter, length, hole locations and quantity to the restraint manufacturer’s instructions and use every required hole. Wood-stud screws must provide the specified embedment after drywall and any permitted spacers. The thin back alone is not a restraint attachment.

    Build the shelving unit

    • Cut the panels and rails; label front, rear and inside faces. Check the two sides match. Mark four shelf-underside lines on both inside faces: 6, 27 3/4, 49 1/2 and 71 1/4 inches above the panel bottoms. These produce shelf tops at 6 3/4, 28 1/2, 50 1/4 and 72 inches.
    • Glue and screw one full-depth side cleat below each line, with its TOP on the line and its 3/4-inch-thick dimension projecting inward. Use six 1 1/4-inch screws through each cleat into the side face at approximately 2, 5.9, 9.8, 13.7, 17.6 and 21.5 inches from the front. Center these screws vertically in the 1 1/2-inch cleat height; pilot and countersink without crushing the wood.
    • Prepare three lower decks with one 45-inch stiffener glued beneath the front edge and one beneath the rear edge. Center each rail across the width, leaving 3/4 inch at each end for the side cleats. The 2 1/2-inch dimension hangs vertically; the 3/4-inch edge contacts the deck. Use five 1 3/4-inch screws from above per rail, spaced along its length and centered across that narrow edge. Clamp flat until cured.
    • Prepare the top deck with the same front stiffener. At its rear replace the narrow stiffener with the 2×4 anchor block laid FLAT: 3 1/2 inches front-to-back and 1 1/2 inches high. Its rear edge is flush with the deck rear and its ends leave 3/4 inch for each side cleat. Glue and fasten with five 1 3/4-inch screws through the top into the block, along a line about 3/4 inch from its front edge. Reserve the remainder of the block for the selected restraint bolts; lay out all holes first to avoid conflicts.
    • With a helper, assemble the two sides and four decks on a flat supported surface. Shelf ends sit directly on the cleats; the stiffeners fit between them. Glue the deck-to-cleat contact and fasten each deck end with four 1 1/4-inch screws from above, centered in the cleat’s 3/4-inch projection. Locate these at roughly 3, 8, 13 and 18 inches from the front to avoid the cleat face screws. Pilot and check that the two screw directions do not collide.
    • Compare the cabinet diagonals and clamp square before attaching the back. Glue the back to the side rear edges and the rear stiffeners/block. Screw the back into the centered side edges at approximately 8-inch spacing, keeping about 2 inches from the ends. Add six screws across each rear rail and the upper block, staying clear of deck screws and future restraint holes. Use 1-inch screws; confirm the points do not emerge through the narrow rails. The full back must be attached before standing the cabinet up.
    • Seal and finish all exposed surfaces and panel edges; allow glue and finish to cure. With a helper, stand the empty cabinet in place, level it and provide full-bearing support under both side-panel bottoms. Do not load the unit yet.
    • Locate two separate wood studs near the upper rear block. Fit both anti-tip assemblies according to their instructions. Their horizontal feet must bear on the top over the solid block, not over an unsupported part of the top. Through-bolt the cabinet side using washers and locking nuts accessible from the upper bay; attach the wall side to studs with the specified screws. Accommodate baseboards only with the hardware maker’s approved spacer or strap arrangement. Secure both restraints before use.
    • Confirm the cabinet is square and stable and all joints and restraints are secure. Try empty bins first. Keep the top clear; place heavier suitable contents in the lowest bay and distribute stored items rather than concentrating weight at the center.

    Prototype checks and limits

    Unreviewed prototype — not build tested. The geometry, material allocation and nominal fastener clearances have been checked digitally. Shelf bending, cleat connections, racking resistance and anti-tip hardware performance have not been physically tested. No shelf or cabinet load rating is assigned. The concept render demonstrates bin storage; the construction drawings and measured hardware determine the build.

    • Do not climb, sit or stand on the shelves. Keep children from climbing the unit. The back is for cabinet bracing; the two stud-connected restraints are still required.
    • Do not use this prototype for engines, batteries, bulk liquid containers, machinery or other concentrated heavy loads. A load rating requires a separate structural design and physical validation.
    • Inspect for sagging decks, loose cleats, splits, backing separation, floor movement and restraint loosening. Stop using the unit and unload it if any appear.
    • Before marking the plan build tested, assemble and check a physical prototype with the actual plywood, fasteners, floor condition, wall construction and restraint hardware.
  • Mobile workshop assembly table

    Mobile workshop assembly table

    Revision 2 · untested prototype. This version specifies the connections and fastener schedule, simplifies the shelf, and adds cutting and joint drawings. It has not been physically build tested. Use the drawings for construction; the cover rendering is an illustration.

    A mobile table with room to clamp

    A 36 × 72-inch plywood top sits on a 30 × 66-inch upper frame, leaving 3 inches of overhang on every side. The default finished height is 34 inches, including your caster assemblies. Four legs are laminated from pairs of 2×4s. Two lower rails attach directly to the inside faces of the legs and support a rectangular 60 × 23-inch shelf—no shelf notches or special rail-end connectors.

    Revision 2 upper frame layout, 30 by 66 inches beneath a 36 by 72 inch top.

    Choose and measure the caster assemblies

    Use four matching plate-mounted swivel casters with both wheel and swivel locks. Each mounts beneath an 8 × 8-inch plywood pad. The leg bears on the pad; two steel corner braces connect the pad to opposite side-grain faces of the leg. This avoids relying on screws driven into the leg’s end grain to retain the pad.

    Select the caster and corner braces together before cutting the legs. Use 2-inch-leg steel corner braces with two usable holes per flange. Check that the horizontal flanges fit within the pad. On a full-size paper layout, mark the 3 × 3½-inch leg footprint, the two brace footprints, and the caster plate. Select a caster bolt pattern whose heads, washers and tool access clear the leg and braces. A plate that cannot satisfy that layout is incompatible with this mounting detail; do not enlarge holes or weaken the leg to force a fit.

    The installed caster assembly height is the distance from the bottom of the wooden leg to the floor. Include the pad thickness, mounting plate, swivel assembly and wheel. Enter that measured height in the calculator. Wheel diameter is not the installed height. All four assemblies must have the same installed height.

    Calculate the legs

    The upper frame rests on the leg ends. With actual 3½-inch-deep rails and a ¾-inch top, the construction above the legs totals 4¼ inches. Leg length = finished height − installed caster assembly height − 4¼ inches. If your material differs, use the actual combined rail depth and top thickness in a manual calculation; the on-page calculator assumes the specified 4¼-inch stack.

    Example: a 34-inch finished table with a 5-inch installed caster assembly needs eight 24¾-inch leg components. A 6-inch assembly reduces those components to 23¾ inches. Choose and measure hardware before batching those cuts.

    Outfeed mode targets a surface ⅛ inch below your equipment’s work surface. For 35-inch equipment and 5-inch caster assemblies: finished table height is 34⅞ inches and leg length is 25⅝ inches. Confirm the appropriate clearance, miter-bar path, fence movement and support position for your actual equipment.

    Revision 2 height stack and rectangular shelf. Finished height equals leg length plus caster assembly plus 4.25 inches.

    Materials and fasteners

    Allow ten straight 2×4×8-foot boards and two nominal 4×8 sheets of ¾-inch plywood. Inspect for twist, splits and damage; the layout is a purchasing allowance, not a guarantee of yield from defective stock. Use wood glue for the leg laminations and multipurpose wood screws intended for wood construction, rather than drywall screws.

    Buy approximately 50 of the 3-inch wood screws, 75 of the 1¾-inch wood screws, and 25 each of the 1¼- and 1½-inch wood screws. Add eight steel corner braces and four casters. Select the 32 machine-bolt assemblies only after laying out the actual hardware. Include washers under heads and nuts where the hardware permits, and enough bolt length for full locking-nut engagement. Keep bolt heads outside the leg’s bearing footprint; all hardware must clear the swivel and brakes.

    Cutting layout

    Boards 1–2: one B from each. Boards 3–4: one D from each. Boards 5–6: split the five C parts as three and two. Boards 7–10: two A parts per board. The layout accommodates a ⅛-inch kerf and the maximum configured 32¾-inch leg length. Shorter legs leave larger offcuts.

    Sheet 1 supplies the top. Sheet 2 supplies the 60 × 23-inch shelf plus four caster pads and four gusset squares. Square and measure the sheets before laying out final cuts. The diagram includes separation for kerfs; keep defects out of the leg connections and caster pads.

    Assembly sequence

    1. Lay out the hardware and record the height. Complete the caster-pad paper layout above. Measure the assembled pad-and-caster height. Select standalone or outfeed mode and write down the calculated leg length. Confirm actual lumber dimensions and plywood thickness before trusting the numbers.

    2. Cut and label. Cut B, C, D and the plywood blanks. Cut all eight A laminations to one checked stop setting. Make a sample cut and measure it before batching. Rip and crosscut the shelf to fit between the legs; if the actual opening is tighter, trim only the clearance needed for a slip fit.

    3. Glue the legs. Pair A pieces broad face to broad face to form four 3 × 3½-inch legs. Use an even glue layer, align both ends, and clamp against a flat reference until cured according to the adhesive instructions. A twisted lamination makes the entire table harder to square.

    4. Assemble the upper frame. Position two C end rails between B long rails. All members stand on their 3½-inch edge. Check a 30 × 66-inch outside rectangle, equal diagonals and no twist. Fasten each C end with two 3-inch screws through B. Put the screw centers about ⅞ inch from the top and bottom edges of B. Use the screw maker’s pilot and countersink guidance, especially near ends and in split-prone stock.

    5. Add the crossmembers. Fit the other three C pieces between B. With 1½-inch rail thickness, four equal clear bays are 14⅝ inches. Clamp each crossmember square, then use two 3-inch screws through B into each end. Recheck the diagonals and frame twist after fastening.

    6. Seat and brace the legs. Place the frame upside down on a flat surface. Orient the leg’s 3-inch dimension along the 66-inch direction and its 3½-inch dimension along the 30-inch direction. Set each leg end directly against the underside of the frame at a corner, with the outside faces aligned. Add two J triangles per corner on adjacent outside faces. Align the triangle’s 8-inch horizontal edge with the frame top and its vertical edge down the leg. Each gets two 1¾-inch screws into the rail and three into the leg. Keep screws clear of the triangular edges and stagger positions on adjacent faces so the screws do not intersect. The frame bears on the leg ends; the gussets retain and brace the connection.

    7. Install the lower rails. Mark a line 8 inches up from the bottom of every wooden leg. Set the top of each D rail on that line, against the inside faces of the two legs on one long side. The 66-inch rail overlaps each end leg by 3 inches. Use two 3-inch screws through the rail into each leg, centered within that overlap, approximately ¾ inch below the rail top and ¾ inch above its bottom. These screws enter leg side grain. Repeat on the other side; check the diagonals and squareness before tightening fully.

    8. Install the caster pads. Center H beneath each leg. Fit two corner braces on opposite leg faces with their horizontal flanges resting on the pad. Drill the pad holes from the actual brackets, deburr the holes, and through-bolt those flanges with washers and locking nuts. Fasten the vertical flanges to leg side grain with compatible 1½-inch wood screws. The wooden leg must bear flat on the pad; no bolt head or washer may sit between them. Check the layout before drilling any caster holes.

    9. Bolt on the casters. Through-bolt each caster plate to its pad using four bolt assemblies sized to the caster’s instructions. Tighten locking nuts without crushing the plywood. Turn each caster through its full sweep and operate its locks to check clearance. Re-measure from the leg bottom to the floor; if it differs from the value used to cut A, resolve that discrepancy before continuing. Fit all four casters, then turn the table upright with assistance.

    10. Fit the shelf. Set G on the two D rails between the legs. It should rest on both rails with a slip fit, not force the legs apart. Install four 1¼-inch screws along each supported shelf edge. Position the screw line over the middle of the 1½-inch rail thickness. Keep unsupported shelf ends free of unnecessary holes.

    11. Attach the top. Center F for 3 inches of overhang on every side. Drive six 1¾-inch screws down through the top into each long B rail. With the top’s 72-inch direction as X, suitable positions are X = 9, 18, 27, 45, 54 and 63 inches; the two screw lines are 3¾ inches in from the long edges. Check those locations against the actual frame and other fasteners. Set heads flush, not deeply buried, and leave the top unglued so it can be replaced.

    12. Inspect the prototype. Check the finished height on the intended floor with all locks set. Inspect every pad, brace, bolt and screw, and check for rocking or racking before use. Recheck fasteners after initial movement. For outfeed, confirm clear travel with the equipment isolated before using it for support.

    Finish and maintenance

    Ease exposed edges and sand splinters. If desired, apply a finish suitable for your shop use, keeping it out of glue joints before assembly. Let it cure before glue-ups. Replace a damaged top or caster pad rather than relying on finish to strengthen it. Periodically check locks and fasteners.

    Prototype notes

    Revision 2 replaces the original four lower stretchers with two side-grain-fastened shelf rails. The shelf is now rectangular and the caster pads are 8 × 8 inches. Do not combine the old shelf, pad dimensions or rail lengths with this revision.

    The dimensions and part relationships have been checked digitally, but the mounting hardware has not been purchased or physically fitted, and the table has not been built. No load rating is established. The configured height and caster ranges describe geometry, not tested performance. Prototype checks still include racking, shelf deflection, lock performance, mounting-pad stiffness, hardware clearance, and actual outfeed fit.

    Fastener reference: GRK’s multipurpose screw information. Follow the instructions for the actual fasteners, brackets and casters you select; the reference is not a certification of this table.
