Read this first

You cannot assemble this bench in your garage and carry it upstairs — at 98 inches wide, it won't fit through the bedroom door. The bench gets built in the bedroom. Cut and paint in the garage; assemble in place upstairs.

The frame at a glance

What you're framing — outer 4x4 posts, slimmer 2x4 dividers between sections, top and bottom rails connecting them. Labeled with every dimension you'll cut to.

Front elevation diagram of the workbench frame. Two outer 4x4 posts, two interior 2x4 dividers, top and bottom rails, with overall width of 98 3/8 inches and frame height of 46 1/2 inches labeled. Three section openings of about 29 1/2 inches each are marked as lens cabinet, general storage, and Husky bay. — Front elevation. The bench butts flush against the left wall (left edge of the diagram) and the right edge stops just before the bedroom door.

Phase A — Cut and prep ~4 hours

Workshop scene: stacks of cut pine 2x4 boards with a 4x4 post on top, a tape measure, speed square, pencil, and circular saw arranged around the lumber on a concrete garage floor.

Acclimate your lumber for 3–5 days

Buy the 4x4s and 2x4s, stack them in your house (not the garage), let them adjust to indoor humidity. Cutting wet pine and then assembling = warped joints later.

Cut the 4x4 outer legs to 45 1/2"

A circular saw can't go all the way through a 4x4 in one pass. Use a speed square as a guide, cut one side, flip the post, cut the other. Sand any tearout flat.

Cut all the 2x4s per the cut list

See the cut list on the reference page. Label every piece in pencil on the back face — "front top rail", "left side bottom", etc. — so you don't have to figure it out twice.

Have the store break down the plywood

At the saw desk at Lowe's or Home Depot. Bring the cut list. The first few cuts are free; ask for them to be square (within 1/16"). This is the single biggest time-saver in the project.

Drill the leveler holes in the bottom of each 4x4 leg

3/8" bit, 1" deep, centered on the bottom face. Hammer a T-nut into the hole flush. Thread the leveler in. The leveler should stick out about 1/2" to 3/4".

Cross-section diagram of a 4x4 leg with a T-nut hammered into its bottom face, a threaded leveler stem screwed up into the T-nut, a plastic foot pad below, and carpet underneath. — Cross-section of a properly installed leveler. The threaded stem screws *up into* the T-nut — there's no gap between the leg and the foot.

What this means

You're installing the foot of the leg. The T-nut is a brass insert with internal threads. Once it's hammered into the wood, you can screw the threaded leveler into it. The leveler can be adjusted up and down to make the bench sit flat on uneven carpet.

Drill all the pocket holes on the 2x4 rails and dividers

Both ends of every rail, top and bottom faces. Two pocket holes per joint. Reference the joinery section on the reference page.

Cross-section of a pocket-hole joint: a horizontal 2x4 rail meeting a vertical 4x4 post, with an angled hole drilled from the bottom face of the rail and a screw driven through it into the post. — The angled "pocket" hides the screw inside the joint, leaving the outside face clean.

Drill the shelf-pin hole columns in the lens cabinet side liners

Two pieces of 3/4" plywood (you cut them in step A4). On each piece, drill two columns of 5mm holes spaced 1 1/4" apart, 1 1/2" in from each long edge. Stop drilling 6" from the top and bottom — you don't need shelf positions all the way up.

Pro tip

Use a strip of pegboard as a drilling jig. The pegboard holes are already evenly spaced; clamp it to your plywood and drill through the pegboard for a perfect column.

Phase B — Pre-paint everything 1 full weekend with cure time

Garage paint booth: sawhorses holding freshly black-painted 4x4 posts and 2x4 boards drying. A second pair of sawhorses holds black plywood door panels. Plastic drop cloth on the floor.

Why pre-paint

If you assemble the bench first and then paint, you'll be on hands and knees painting carpet baseboards and the underside of cabinet shelves with a brush. Paint everything flat in the garage before it's a bench. You'll save 5 hours and the finish quality jumps a tier.

Set up your spray area in the garage

Plastic sheeting on the walls, drop cloths on the floor. Lay out two sawhorses for parts to sit on while painting. Make sure you have ventilation. Do not spray paint in the bedroom.

Sand all 4x4 and 2x4 parts to 180 grit

Hit any rough edges, splinters, and saw marks. Wipe with a damp cloth, let dry 15 minutes.

Mask the joint faces and pocket holes

Use painter's tape to cover the ends and edges where parts will touch each other during assembly. Paint inside a pocket hole gums up the screw. Paint on a glue surface kills the bond. This step is annoying but mandatory.

Prime everything — especially knots

Zinsser BIN or Cover Stain. One full coat over all wood. Don't skip this — pine knots will bleed orange-yellow stains through black paint for months otherwise.

Light sand with 220 grit, wipe clean

Just a knock-down sand. Take off any nibs or raised grain from the primer. Wipe with a tack cloth or damp rag.

Spray paint coat 1 on all parts

All 4x4s, 2x4s, plywood doors, lens cabinet side liners. Spray plywood doors on a flat surface, flip after dry to do the other side. Let dry per the paint label (Advance: 16 hours).

Doors warp if painted on only one side

Always paint both faces of every plywood door, even though only one shows. Same number of coats per side. Single-side painting causes plywood to bow within days.

Iron-on edge banding on the doors

While coat 1 is drying, work on the doors. Iron-on banding goes on with a clothes iron set to "cotton" / no steam. Trim the overhang with a sharp utility knife, sand flush with 220 grit.

Light sand again with 220, spray coat 2

Second coat covers any thin spots and gives the finish depth. Sweep the edges of the doors to catch the edge banding (paint sticks fine to the banding after a light scuff).

Let cure 48+ hours before assembly

Fresh paint dents and scratches very easily. If you can stretch this to 72 hours, do.

Phase C — Carry the parts upstairs ~30 minutes

Move all painted parts to the bedroom

Frame parts, plywood doors, plywood cabinet bottoms, hardboard backs, lens side liners. Lay them out on the carpet in roughly the order they'll be assembled.

Bring up your tools

Drill, driver, level, tape measure, stud finder, lag bolts, washers, socket and ratchet for the lag bolts, painter's tape, pencil, screws.

If you got this far

Take a photo of the finished bench from the same angle as the hero image at the top of this site. Send it to me. I want to see what it actually looks like in your room.
