Art Deco Speaker Enclosures

I am building a bookshelf and want to incorporate into it the speakers that I use for my television. This is the design using Sketchup for enclosing the subwoofer speaker. I need a porous material to allow the sound to radiate so in this project I decided to use metal. This is my first venture into using this material.

My usual construction style is Arts & Crafts. I've decided to depart from that style for this project and try Art Deco using sapele veneer. I'm no expert, but this style uses metal, contrasting pigments, and curved profiles. The curves are especially challenging because I solely use veneer. The previous posts show my construction techniques for the veneered shelves. I have two enclosures that are a mirror of each other. The left enclosure holds the woofer and the right is empty. Since the woofer emits sound from the front and right side, the porous metal needs to be on these sides.

The left side of the enclosure is a slightly curved surface using sepele veneer. It has been bonded to a piece of 1/8" MDF. The curve is created by forcing the MDF into routed curved slots in the top and bottom pieces.

For the porous metal, I've used sheet aluminum that is 1/32" thick. Creases are very noticeable, so cutting it was a concern. I've quite successfully used my tablesaw with an old crosscut blade. I've painted and used a water finish before inserting the metal. The blue tape protects the wood from scratches when I install the metal sheet.

The curve in the metal sheet is formed by bending it around an aerosol paint can. The cutouts in the back accommodate the speaker wires and power connection.

Curving the surface of the sheet creates a fair amount of vertical strength, but the rest of the enclosure is intended for vertical support and the ¼" plywood inserts resist racking in the front-to-back and side-to-side directions.

This enclosure is on a shelf which is the bottom of the bookshelf. A square hole in this shelf will allow the woofer to sit on the floor. I'm hoping this will allow the bass sound to still radiate into the floor and prevent unwanted vibration into the bookshelf.

Mission Style End Table with Slate, Part 3

Here is an update on the end table project. The complex part are the curved sides which bow out slightly from each side to match the curve of the top. The picture at right shows the bottom of the table with a coat of gel stain that fills the grain of the oak. I'm following my Mission Style finish recipe that I blogged about earlier. After the stain dries, I'll sand it and then spray a brown dye.

Economy and Reduced Complexity

Using solid quarter-sawn white oak would have been costly and showing flake on all four sides of the legs would have been difficult. This project almost entirely uses veneer. The core of the legs is ¾" plywood with ¼" MDF sandwiched between them. Quarter-sawn white oak veneer is glued to all four sides.

Enabling the Curved Sides

To create the bowed sides, I've cut a 15° slot into the sides of the legs. I don't want the curve all the way to the floor, so the challenge is only having the slot partially down the leg. Veneer allows me to cover the slot on bottom part of the leg. I sawed the slot the entire length of the leg, then filled the slot with filler where it wasn't required. Veneer was glued over the top and I exposed the slot again with a small diameter router bit on my router table.

Mission Style End Table with Slate, Part 2

Here is the table top with the slate installed. I sprayed it with Deft Clear Wood Finish, a lacquer finish with a satin sheen. Both the wood and the slate were sprayed. The lacquer added more amber color to the top making it a bit darker than I wanted. I'm starting to have reservations about using slate. The finish highlights any scratches and the surface is too bumpy. I plan to attach the top with screws so I can change it later if I get motivated.

I want to have an enclosed shelf underneath the top to store books and other stuff. To make it challenging, I'm trying to have curved sides to match the curve in the top. I've never tried bending wood before because it looked pretty involved. I wanted to see whether I could just veneer quarter-sawn oak to ⅛" MDF and bend it to the curve I needed.
To experiment, I've cut 15° angle slots into what would be the table legs. I've screwed a board to the legs and wedged a narrow board under the MDF at the peak of the curve. I was worried that the curved veneer would flex when pushed, but it's very stiff. This may work!
