How to Build a Desktop Book Caddy

Tools you'll need

Tape measure - Check actual stock and use the regional dimensions.
Sharp pencil - Mark waste, part names, screw centers and bounded glue zones.
Square - Keep cuts and upright joints square.
Saw - Square crosscuts across the full board width only: a suitable sliding miter saw, circular saw with guide, hand saw or retailer cutting service.
Drill/driver - Use controlled torque to seat countersunk heads flush without crushing wood.
Clearance, pilot, and countersink bits - Match the selected screw's shank and core; make a test joint in an offcut. Start pilots in the upright edges at about 5/64 in (2 mm), roughly 70% of the thread root diameter for softwood per the USDA fastener chapter, and enlarge only if the offcut test splits or the screw binds.
Clamps - Hold each upright square to the base while drilling and assembling.
Sanding block with 120- and 180-grit abrasive - Keep mating faces flat while easing exposed edges.
Safety glasses - Wear for cutting, drilling and sanding.
Hearing protection - Use when powered tools produce hazardous noise.

Materials

Planed pine board - One straight, flat, dry, untreated board supplies all four pieces. Verify actual thickness, width and usable length against the plan before cutting.
7 Countersunk wood screws - Buy a small pack (at least eight): #8 x 2 1/2 in in the US, or 4 x 60 mm elsewhere. Through a 3/4 in (19-20 mm) base the screw reaches about 1 3/4 in (40-44 mm) into the upright, so at least 32 mm of full-depth thread remains after excluding a tapered point of up to 8 mm. Shorter 2 in screws leave only 22-26 mm of thread and do not meet this rule. Prefer fully threaded screws with clearance holes through the base.
Interior PVA wood glue - Glue the full back joint and only each end's marked central 2 in zone; follow product clamping and cure directions.
4 Self-adhesive felt furniture pads - Use four equal-thickness pads near the base corners after the finish cures; verify stable placement on the intended desk.
Water-based clear satin wood finish - Single finish option for the first contract. Follow label preparation, ventilation, recoating and full-cure directions before storing books.

Step by step

Check your books and desk space

Use the outside dimensions to check the desk footprint. Compare your books' cover depth with the clear inside depth and their combined spine widths with the clear inside width. Choose a wider size if needed. This caddy is intended for a few paperbacks or notebooks on a flat desk, not for carrying books. Check your actual books rather than assuming every notebook format fits.

Inspect the board and mark four parts

Choose dry, straight, flat pine without splits or loose knots. Measure its actual thickness, width and usable length against the plan. Identify grain along the board length. Review the stock diagram for one base, one back and two ends, plus trim and kerf allowances. Mark each part and the waste side; do not lay out finished lengths back-to-back without allowing for the saw cuts. Choose the better face of the base as the inside face and mark its underside clearly: all seven screws enter from the underside, so a reversed base puts countersunk heads inside the book compartment.

Crosscut the base, back and two ends

Clamp and support the board. Square one reference end within the trim allowance, then crosscut the base and back at the selected outside width. Crosscut two ends at the end length. Keep every piece at the original board width; no rip cuts are needed. Cut successively from the new square end, keeping the blade on the waste side. Label all four parts and compare the matching pairs. Recalculate the stock plan if actual kerf or defect trimming exceeds its allowance.

Sand and dry-fit the four parts

Sand with 120 grit, then 180 grit. Ease exposed edges but leave mating faces flat. Stand the back on the base at the rear and both ends on the base at the outside edges, flush at the front. The full original board width becomes the height of each upright. Check square corners and keep the end-to-back gaps shown in the model: 1/8 in in the US or 3 mm elsewhere.

Mark and drill seven screw positions

Follow the underside drilling diagram: three screws along the back thickness centerline at one-quarter, one-half and three-quarters of the outside width; two screws per end along its thickness centerline. Each end pair sits one inch in the US or 25 mm elsewhere to either side of the end's center. Clamp each upright square. Drill clearance holes through the base and matched pilot holes into the upright, then countersink only until heads will sit flush. Test the selected screws in an offcut first; use the specified length and thread engagement. Pilot the upright edges at about 5/64 in (2 mm) unless your offcut test shows the screw needs more; drill square to the edge so the screw stays centered in the 3/4 in (19-20 mm) thickness.

Glue and fasten the back

Apply a thin, even glue film along the full back-to-base contact. Both grains run along the caddy width. Clamp the back square and flush with the rear edge, then drive its three underside screws until the heads are flush. Remove squeeze-out as the glue label directs. Keep the other joint areas clean for their marked glue zones.

Glue the marked zones and fasten both ends

Mark a central glue zone on each end's bottom edge and matching base contact: 2 in long in the US or 50 mm elsewhere, spanning the end's thickness. Apply glue only inside that zone. Clamp the end square and flush at the front, then drive its two underside screws flush. Repeat for the other end. Leave the remaining contact unglued, remove squeeze-out beyond the zone and keep the rear gaps open. Do not screw or glue the ends to the back; the limited glued area leaves the rest of the cross-grain joint free to accommodate movement.

Let the glue cure and check the joints

Keep the caddy unloaded for at least 24 hours, or longer if the glue label directs it; PVA reaches working strength well before that but should not be stressed sooner. Remove clamps and inspect all seven screw heads, the back joint and both end joints. Check that the base lies flat, the ends are square and firm, and both rear gaps remain open. Correct splits, loose joints, proud screws or rocking before use.

Apply a clear finish

Remove sanding dust and apply the selected indoor clear satin wood finish to accessible faces and edges. Follow its label for preparation, coat thickness, recoating and full cure. Keep the four pad locations clean and do not place books on uncured finish.

Fit four pads and arrange your books

Once the finish is fully cured, attach four equal-thickness felt pads near the underside corners. Set the empty caddy on its intended flat desk and check that it does not rock. Add suitably sized books gradually, keeping them upright. Confirm the caddy remains stable and does not slide or tip. Remove the books before moving it; it has no carrying handles.

Tips

Check your actual books against the plan's inside depth and width before cutting — “notebook” and “paperback” sizes vary more than you'd expect.
Mark the base's underside before drilling. All seven screws go in from underneath, and a flipped base puts the countersunk heads inside the compartment where your books sit.
Glue only the marked zones on the end pieces, not the full contact area — leaving the rest of that joint unglued lets the wood move naturally instead of splitting.
Test your screws in an offcut first. The pilot hole size in this plan is a starting point; if the screw binds or the offcut splits, go up slightly before drilling the real parts.
Give the glue its full cure time — at least 24 hours — before loading any books. A joint that looks solid isn't at full strength yet.

FAQ

What size books does this caddy fit?

That depends on the width you choose — check your books' cover depth against the caddy's inside depth and their combined spine widths against the inside width, and size up if you're not sure.

Why is only part of each end piece glued?

The base and back are glued along their full contact, but each end piece is only glued in a marked 2 in zone. Gluing the full end-to-base joint would fight the wood's natural movement across the grain and risk splitting over time.

Can I carry the caddy while it's full of books?

It's designed to sit on a desk, not be carried loaded — there are no handles. Remove the books before moving it.

Do I need to finish it?

The clear satin finish is optional but recommended since the caddy sits out on a desk. Either way, let any finish fully cure before setting books on it or attaching the felt pads.

Which screws should I use?

Countersunk wood screws sized to reach about 1 3/4 in into the end pieces through the 3/4 in base — in the US that's a #8 x 2 1/2 in screw. Shorter screws don't leave enough thread engaged to hold securely.
