Three vertical 2x4 rack frames on a rolling base — stores full-length lumber upright instead of leaned against a wall.
| Part | Qty | T × W × L | Material | ✓ |

| Bottom frame middles Divides the bottom frame into the three storage bays. | 4 | 1 1/2" × 3 1/2" × 27" | 2x4 | ☐ |
| Upright legs Two per rack frame, three rack frames. | 6 | 1 1/2" × 3 1/2" × 60" | 2x4 | ☐ |
| Upright rungs | 9 | 1 1/2" × 3 1/2" × 24" | 2x4 | ☐ |
| Top tie-ins Ties the three rack frames together at the top. | 4 | 1 1/2" × 3 1/2" × 24 3/4" | 2x4 | ☐ |
| Item | Qty | ✓ |
|---|---|---|
| Construction lumber, 2x4, 10 ft Line total for all ten boards. | 10 each | ☐ |
| Locking swivel casters, 5" Line total for all four — a loaded lumber cart is heavy and low-clearance casters bind on shop floor debris. | 4 each | ☐ |
| 2-1/2" self-tapping star bit screws | 100 each | ☐ |
| 2-1/2" pocket hole screws Optional, for the upper tie-ins. | 16 each | ☐ |
Overall cost: $$. Lumber varies by region, species, and season, so we give a band rather than a figure.
Tools: Circular Saw, Combination Square, Drill / Driver. Materials: Construction lumber, 2x4, 10 ft, 2-1/2" self-tapping star bit screws
Screw the two side rails, two end pieces, and four middle dividers into a rectangular frame with three evenly spaced openings. Two screws per joint, driven with the star bit screws.
Get this frame square before moving on — every rack frame above it registers off this base, so an out-of-square bottom telegraphs up into a cart that leans.
Tools: Bar / Pipe Clamps, Circular Saw, Drill / Driver. Materials: Construction lumber, 2x4, 10 ft, 2-1/2" self-tapping star bit screws
Build three identical ladder-style frames from the upright legs and rungs, two screws per joint. These are what actually separate and support the standing lumber.
Tools: Combination Square, Drill / Driver. Materials: 2-1/2" self-tapping star bit screws
Level the bottom frame first, then stand each rack frame at 90 degrees to the base, checking plumb with a square before driving four screws per joint.
Do this one frame at a time rather than all three loosely stacked — a rack frame that's slightly out of plumb is much easier to correct before the next one is screwed in next to it.
Tools: Drill / Driver, Impact Driver. Materials: Construction lumber, 2x4, 10 ft, 2-1/2" pocket hole screws
Cut and install the four top tie-in pieces connecting the tops of the three rack frames, either with pocket screws from inside or angled star bit screws from top and bottom.
This is what stops the cart racking side to side once it's loaded and rolling — don't skip it even though the bottom frame already feels solid.
Tools: Drill / Driver. Materials: Locking swivel casters, 5"
Attach the four locking casters to the underside of the bottom frame, screwing into both the frame rails and the middle dividers where possible for a wider fastening pattern.
Check that all four lock before loading the cart — a cart that rolls away while you're pulling a 10-foot board off the top rack is a hazard, not a convenience.
