Hollow Panel Waterfall Console

Overall 60 W x 13 1/4 D x 30 H in / Indoor display furniture

A thick frame without solid slabs

Plywood skins and short internal supports form the sides and lower plinth. Narrow solid-wood face frames cover the open edges on both faces. The top has corner cleats and a center support underneath; it is not a solid timber slab.

Choose the right project

Accurate 45-degree bevels and miters make this an intermediate build. Read every step first, practice on offcuts and dry-fit the shell before fastening. Do not scale measurements from the sketches.

Choose straight, dry trim and flat plywood with sound, attractive faces. Oak is needed for the open-grain highlighted finish shown here.

Verify on scrap

Use pocket screws intended for the plywood and wood species. Match pilot holes to the selected wood screws. Test driving depth in offcuts: screw tips must stay inside the plywood face, not break through the veneer.

Cut with full support

Wear eye and hearing protection and use dust extraction and suitable respiratory protection. Support both sides of the cut without pinching the blade. Clamp the guide outside the entire saw path. Disconnect power before changing blade, bevel or depth settings.

Control fastener paths

Keep hands away from the back and edges of any nailing or drilling location. Set the nailer nose squarely on the intended wood face and confirm solid backing behind it. Disconnect the nailer before adjustments or clearing a jam.

Protect the veneered surface

Use padded clamp jaws. Remove glue squeeze-out before finishing, and do not sand through the thin oak face veneer. Do not use filler to hide a loose structural joint.

Keep the console stable

Work with a helper when turning the shell. After assembly, place it on a level floor and fit an appropriate anti-tip restraint. It is not a seat, step, climbing frame or tested support for heavy equipment.

Inches are the cutting dimensions. Millimetres are rounded conversions. All plywood pieces are 11 3/4 in / 298.5 mm deep.

Measure the assembled shell before the final trim cuts. The face frames must fit the actual shell, not force it into shape.

Two different angled cuts

Bevel both short ends of A at 45 degrees so its outer face is the 60 in long side. Bevel only the upper end of each C. Cut both ends of H and I with opposing 45-degree miters in the wide face: the listed length is the long outside edge.

Leave the other ends square

B, D, E, F and G are square-ended. The lower ends of the outer sides C remain square and reach the floor.

One plywood sheet is sufficient

A practical layout uses three 11 3/4 in wide strips cut along the 8 ft sheet length. Allocate A plus one C to strip 1; B plus the other C to strip 2; both D pieces and all E and F ribs to strip 3. Leave the remaining sheet as spare material.

Keep kerf and defects out of the parts

The first two strip allocations use 90 in and 88 1/2 in before saw kerfs. The third uses 68 1/4 in. Mark blade waste and allow for end trimming and angled cuts; these are layout allowances, not extra finished lengths.

Use each trim board deliberately

Each 8 ft 1x4 can supply one 60 in horizontal and one 30 in vertical trim piece. Keep the long points on the chosen outside edge, and allow saw kerfs and small fitting trims. Reject bowed or damaged lengths rather than stretching the cut list.

Confirm the actual thickness

The nominal shell is 60 in wide: 58 1/2 in bottom plus two 3/4 in outer sides. Its finished depth is 11 3/4 in plywood plus two 3/4 in face frames. If material differs, dry-fit and resolve the affected fits before cutting all parts.

A x 1 / C x 2 / Circular saw, guide and clamps

Cut the long points accurately

Test a 45-degree bevel on scrap. Mark A and C on their outside faces, support the plywood fully and cut on the waste side. The top bevels meet the side bevels to make two square upper corners.

Keep the setup clear

The guide must not move. Clamp it across the guide and plywood with opposing pads, outside the saw path. Keep the saw shoe flat on the panel. The sketch omits the operator; use both prescribed grips during the actual cut.

Plywood pockets

Use the 3/4 in / 19.1 mm material setting. Drill three pockets at each short end of B. Drill three along one 11 3/4 in long edge of every E and F support rib, with the screw path exiting through the edge that meets its receiving panel.

Center support pockets

Identify one G cleat as the center top support. Drill two pockets at each of its short ends using the 3/4 in setting for the 3/4 in receiving face trim. This is not the usual same-thickness 2x2 joint: verify the jig setup and 1 1/4 in screw path on scrap first.

Keep the screws accessible

Mark the hidden faces and the final front and back. The center-support end pockets must remain accessible after the support is attached beneath A. Do not drill these pockets in the two corner cleats; they use straight wood screws.

Count the planned connections

These locations total 37 pocket screws: 6 at B ends, 9 in E ribs, 18 in F ribs and 4 at the center support. Keep extra screws for scrap setup and damaged fasteners.

B x 1 / E x 3 / Glue and 1 1/4 in pocket screws

Work on the hidden underside

Lay B on a protected surface with its underside up. Stand the three E ribs on their 11 3/4 in edges, perpendicular to B. Space them evenly along the length; their exact spacing is not critical.

Fasten without twisting

Keep each rib square and its full edge seated in glue. Drive three pocket screws per rib. When turned upright, the 2 3/4 in ribs and 3/4 in panel put the top of the bottom panel 3 1/2 in / 88.9 mm above the floor.

C x 2 / B assembly / Glue and six 1 1/4 in pocket screws

Transfer the height

Set the bottom assembly on its ribs. Stand one C beside it with its square end on the floor and its bevel at the top. Mark the top surface of B on the inside of C. Repeat for the opposite side.

Attach the two sides

Align B to these marks and keep all front and back edges flush. Glue the B-to-C joints and drive the predrilled end pockets. Compare diagonals and check both sides square before the glue sets.

A x 1 / Two G corner cleats / Glue and twelve 2 in screws

Close the upper corners

Fit A between the two beveled side tops. Align the outside edges and tape the joints while checking that both corners close at 90 degrees. Seat a G cleat against the two inside faces of each corner.

Drive from the cleat into the skins

Glue and fasten each cleat with three 2 in screws toward the top and three toward the side. Stagger the two rows so their paths do not intersect. Use suitable pilot holes and stop before the heads crush the wood.

Position the remaining G

Center the third 11 3/4 in cleat under A, running from front to back. Keep its short ends flush with the plywood edges so they can meet the two top face-frame rails. The nominal gaps to the corner cleats are about 27 in / 685.8 mm.

Attach it to the top

Apply glue at the top contact face. Drive three 2 in wood screws through G into A. The screw penetration must remain within the top skin. Leave the two pockets at each short end facing outward and accessible.

Keep the final connections for later

After the face frames are nailed on, these four end pockets receive 1 1/4 in pocket screws into the top front and back trim. Do not block the pockets or substitute screws that emerge through the visible trim.

F x 6 / D x 2 / Glue, 1 1/4 in pocket screws and 1 1/2 in nails

Add three ribs per side

Attach the F ribs to each outer side with glue and pocket screws. Set one on B, another about 12 in / 304.8 mm above B and another about 22 in / 558.8 mm above B. Keep the ribs clear of the corner cleats.

Nail only into backing

Align each D with the top surface of B and seat it against the ribs. Glue and nail D into those ribs. Mark their positions first: the nailer nose must contact the skin directly over solid backing, never the hollow gap.

H x 4 / I x 4 / 1 1/2 in brad nails / Four pocket screws

Fit one piece at a time

Start with a bottom I, then the two H stiles, then a top I. Trim the 45-degree miters gradually for a closed fit with flush outside edges. Repeat on the opposite face; both frames have the same outer size.

Aim through trim into the shell

Clamp with padded opposing jaws and drive nails through the trim into the plywood edges or cleats behind it. Keep the nose off the broad side face. Finally drive the four center-support pocket screws into the two top trim rails.

First face frame / Four closed miter corners

Check continuity around the opening

The four trim pieces form one rectangular frame. Check that the bottom rail reaches the floor, the top rail aligns with A and the stiles cover the hollow side edges. All four miters should close without forcing the shell.

Inspect the grain and surface

A pronounced cathedral grain is one possible face arrangement. The grain is cosmetic; do not use weak, split or loose knots at fastener locations merely to match a pattern.

Opposite face frame / Center support fastened at both ends

Inspect the other face separately

The opposite frame must be just as square and flush. Quieter, straighter grain can give it a different appearance without changing any dimensions. Inspect every miter, rather than assuming the first face proves the second is aligned.

Confirm the hidden work

Before finishing, verify the center support is fastened into both upper trim rails. Look underneath and check every cleat, pocket screw and skin-to-rib connection for a secure, fully seated fit.

Nail holes and small miter gaps / Compatible wood filler

Inspect under angled light

Mark small nail holes and cosmetic seam gaps. Check that each joint is secure first. A large open joint, loose trim or misaligned shell needs refitting, not a thick layer of filler.

Test the color response

Use matching offcuts to test filler with the complete finish. Filler can accept stain differently from oak. Keep it local to the defect instead of spreading it across the surrounding grain.

Filled nail holes / Closed cosmetic seams

Apply a small amount

Press suitable filler into the nail holes and minor gaps. Follow the product instructions for application thickness and drying. Remove excess without rounding the crisp mitered edge.

Recheck before sanding

Allow the filler to dry fully. Look again for shrinkage or remaining pinholes, and touch up only where needed. The finished corner should stay straight, square and firmly joined.

Solid face trim slightly above plywood / Sanding block

Feel for a small ridge

Run a straightedge across the trim and top skin. If the solid trim is only slightly proud, mark that high area. Refit a major mismatch rather than sanding the whole veneered top down to it.

Protect the plywood face

The visible oak veneer is thin. Keep coarse abrasion on the high solid-wood trim only and check often. Do not round the outside corner or sand through the face layer.

Leveled solid trim / Smooth oak veneer

Refine the surface gently

Once the trim is flush, sand the remaining surfaces lightly with 120, then 180, then 220 grit as appropriate for the finish. The aim is a smooth surface without erasing the edge definition.

Remove every trace of dust

Vacuum with a soft brush and wipe as directed by the finish manufacturer. Inspect for glue residue, sanding scratches and bare spots before opening the stain.

Compatible conditioner and black stain / Oak test piece

Follow one compatible finish system

Test the conditioner, stain and intended protective finish together. Apply the conditioner and re-sand raised grain only as directed. Apply the black stain evenly to the prepared oak.

Let the stain dry

Keep the console on a clean protected surface with ventilation. Follow the current product drying times, not a fixed clock estimate. Inspect the unhighlighted black finish before deciding whether to add grain wax.

Compatible pale grain-highlighting wax / Clean cloths

Test before the visible surfaces

Use an oak offcut or hidden area to confirm compatibility and the amount of pale grain contrast. This effect relies on open oak pores and will not look the same on smooth, closed-grain wood.

Apply and remove the excess

Buff the wax into the surface, then wipe across the grain after the product's stated dwell time. Leave pale material in the pores, not a thick cloudy film on top. Use only a finish combination approved by its manufacturer.

Pale pores over charcoal oak / Cured finish

Look along the light

Check the top and both faces for an even sheen, clean corners and consistent grain highlighting. Remove smears with the method approved for the chosen product before it cures.

Let the surface cure

Do not add a clear film over wax unless that combination is expressly approved. Allow full curing before placing objects on the console. Keep wet containers, abrasive objects and hot items off the finish.

Inspect the complete assembly

Verify the top, bottom and both hollow sides are secure. All nails should be seated without exposed points, and all fasteners should stay within the wood. Check for rocking, loose joints and damaged veneer before use.

Secure the furniture

Place the console on a level floor. Fit an appropriate anti-tip restraint to a solid internal cleat or other verified structural location and to suitable wall framing or anchors. Do not attach a restraint only to decorative trim or a hollow area.

Use it as a display console

No load capacity is established by this guide. Do not sit, stand or climb on it, and do not assume it supports an aquarium, stone top or heavy equipment. Keep heavy objects low and away from the front edge.

Maintain the finish

Clean with products approved for the coating. Protect the surface from standing water and heat. Inspect fasteners, restraint and finish periodically, and stop using the console if a joint loosens or the structure is damaged.
