A tambour-front cabinet looks more complicated than a hinged-door cabinet, but the mechanism is straightforward: narrow wood slats are joined on their backs so they can curve around a track. The project is best suited to an intermediate woodworker. You need accurate repeated cuts, a router or table saw, and patience when fitting the door. Plan on a weekend for the case and another day for the tambour and finish.

Planning and Materials
A useful finished size is 30 inches wide, 36 inches high, and 14 inches deep. That gives enough room for shelves without making the tambour too large or heavy. Build the case from solid panels or frame-and-panel construction, but do not glue wide solid-wood panels rigidly across their grain. Seasonal movement can split the case or jam the door.
| Part | Recommended material | Notes |
|---|---|---|
| Case sides and top | 3/4-inch solid wood panels or edge-glued boards | Allow for movement with buttons, figure-eight fasteners, or slotted screws. |
| Back | 1/4-inch plywood or narrow solid-wood boards | Plywood is the cheaper, more stable choice. |
| Tambour slats | 1/2-inch-thick straight-grained wood | Use clear stock with no knots or short grain. |
| Tracks | Hardwood strips or plywood-lined grooves | Waxed hardwood tracks run quietly and are easy to repair. |
| Interior shelf | 3/4-inch plywood or solid wood | Use adjustable shelf pins if storage needs may change. |
Choose a stable species such as walnut, cherry, maple, or quarter-sawn white oak. Avoid very wide, flat-sawn boards for the sides unless you understand how you will accommodate movement. You will also need a router with a straight bit, a table saw or bandsaw, clamps, a drill, a marking gauge, and a reliable way to sand repeated parts. A router bit set for woodworking is useful, but a single sharp 1/2-inch straight bit is enough for most of this build.
Build the Cabinet Box
Mill the case parts to identical thickness before cutting them to length. For a 30-by-36-inch cabinet, cut two sides at 36 inches by 14 inches, a top and bottom at 28 1/2 inches by 14 inches, assuming the sides remain full width. Cut a 1/4-inch-deep by 1/4-inch-wide rabbet on the back inside edges for the back panel.
Join the case with loose tenons, dowels, or a housed dado. A simple dado is strong and easy to repeat: cut a 3/8-inch-wide groove in each side and fit the top and bottom into it. Dry-assemble the box before gluing. Check both diagonals; if they differ by more than 1/8 inch, correct the case before the glue sets.
Attach the top in a way that allows side-to-side movement. Screws through elongated holes, figure-eight fasteners, or tabletop buttons work better than a rigid cross-grain glue joint. Install the back after the case is square. It prevents racking, but do not use it to pull a badly misaligned box into shape.
Install the Tambour Tracks
The door needs a continuous path: across the front, around one side, and into a storage pocket. The simplest layout has the tambour roll into a pocket behind the left or right side panel. Make the pocket at least 1 1/4 inches wide and slightly taller than the door so the slats do not scrape.
Rout matching grooves in the top and bottom panels before final assembly. A 3/8-inch-wide, 1/4-inch-deep groove is a reasonable starting point for 1/4-inch-thick door edges or guide strips. Round the transition from the front track into the pocket with a template or a series of closely spaced cuts. Sharp inside corners are a common failure point: the tambour binds there even when the straight tracks are perfect.
Line the tracks with smooth hardwood strips if the case wood is soft. Sand the strips to remove any raised grain, then apply a thin coat of paste wax. Do not flood the tracks with finish. Thick varnish or paint can reduce the clearance enough to stop the door.
Make the Tambour Door
Cut enough slats to span the opening, plus two or three extras. For a 28-inch-wide opening, 1/2-inch-wide slats usually require about 56 pieces. Make each slat 1/32 inch shorter than the clear distance between the tracks. This small allowance prevents binding when humidity rises.
Use a stop block to cut every slat to the same length. Mill the front face flat and ease its two long edges with a 1/8-inch round-over bit. On the back, leave a flat center section and soften the edges so neighboring slats can bend. Test five slats together before producing the entire set. If the assembly will not curve smoothly around the track, fix the profile now rather than after sanding 50 parts.
There are two practical ways to join the slats:
- Canvas backing: Glue the slats face down to tightly woven canvas with a flexible wood glue. Leave a 1/32-inch gap between slats. This is inexpensive and forgiving, but the canvas can show at the edges and may eventually loosen.
- Linked slats: Rout shallow grooves on the backs and install flexible tambour tape or narrow fabric strips. This looks cleaner and bends more predictably, but requires more careful routing.
Canvas is fine for a painted cabinet or a first tambour project. For a high-use cabinet, tambour door fabric tape is worth considering because it stays concealed and gives the slats consistent spacing. Keep glue off the front faces and remove squeeze-out before it dries.
Fit and Test the Door
Finish-sand the slats to 180 grit before assembly. Apply finish to the front faces while the tambour is still flat, but keep finish off the backing and track edges. A wipe-on oil is easier to repair than sprayed lacquer, though lacquer gives better abrasion resistance. Let the finish cure fully; a slightly tacky door will feel defective even if the woodworking is correct.
Insert the top edge of the tambour into its groove, flex the assembly around the track, and lower the other edge into place. It should move with one hand and stop without springing back. If it binds, look for glue squeeze-out, a proud slat, a tight curve, or a track that is not parallel. Do not force it. Forcing usually tears the fabric or breaks a slat.
Add Shelves and Finish the Cabinet
Install the shelf after the door operates smoothly. A fixed shelf can strengthen the cabinet, but adjustable pins are more useful for changing storage. Keep the shelf front at least 1/2 inch behind the tambour path so items cannot catch the moving door.
Ease all exposed corners with a small round-over, then apply two or three thin finish coats, sanding lightly between coats. Before loading the cabinet, cycle the door at least 20 times. Test it again after the finish has cured for several days. If the cabinet will live in a damp garage or unheated room, choose plywood for the back and shelf and leave slightly more door clearance. Indoor seasonal changes are normal; a tambour that works only in the shop is not finished.
For repeated slat work, a table-saw stop block is more valuable than an expensive specialty jig. Accuracy, clean tracks, and controlled clearance determine whether this cabinet feels refined or frustrating.
