PROJECT: Building a Framed Lampshade

PROJECT: Building a Framed Lampshade

This six-paneled, maple and rice paper lampshade project will test your precision and patience. After experimenting with many different angle combinations for cutting the wooden parts, I was able to put together a list of measurements and a couple of assembly jigs to help improve your success in making a framed shade like mine. Note that the overall height of my shade is intended to complement the size of the box elder lamp Rob made.

Using a Digital Angle Gauge

Setting up Wixey digital angle gauge

Wixey’s Digital Angle Gauge is a helpful battery-powered accessory for setting blade tilt angles without using a protractor or conventional bevel gauge.

It features an LED readout that reports angle settings to a tenth of a degree. To use the gauge, set its magnetized base against a saw blade and zero out the display.

When you tilt the blade, the Angle Gauge will report its exact tilt as it changes. For this lampshade project’s 29-degree bevels, the gauge’s simple and accurate operation came in very handy!

Cutting Panel Sides, Bottoms and Tops

Pieces for making lamp shade laid out
Six bevel-edged strips (left) and six flat-edged strips (right) will form the shade’s six panel frames.

I started by ripping a piece of 1/2″-thick maple stock, measuring 5″ x 24″, into six long strips that would become the 12 side pieces for the shade’s six panels.

Cutting strips with 29 degree beveled edges
Make sides for the shade’s six panels by first bevel-ripping both edges of the maple workpiece to 29 degrees.

To do that, I tilted my table saw blade carefully to 29 degrees using a Wixey Digital Angle Gauge, and bevel-ripped both long edges of the board.

Ripping strips of wood for lamp shade frame
Reset the blade to 90 degrees, and adjust the rip fence so the beveled offcut will be 1/2″ wide. Rip this strip free to form two panel sides. Repeat for the other edge.

Returning the saw blade to 90 degrees, I then ripped two 1/2″-wide x 24″-long strips with the bevel cuts on one edge of each. Repeat this process to make four more long strips with one beveled edge and one square edge.

Trimming ends of lamp shade frame
Crosscut the six bevel-edged strips into 12 side pieces for the shade panels. With a miter gauge set square to the blade, trim them each 11″ long, making sure to square their ends.

Now take what remains of this piece of stock and rip it into six more 1/2″-wide strips with your blade kept at 90 degrees.

Using flip stop on miter gauge to guide lamp shade frame cut
The author used a flip stop on his miter gauge to set these part lengths.

Each of the bevel-edged strips you just made will become two panel side pieces. Using a miter gauge on the table saw, I cut a dozen of these panel sides to 11″ long, carefully squaring up their ends.

Making twelve degree angled cuts in lamp shade frame
Cut the ends of the panel top and bottom pieces to 12 degrees.

You’ll use the remaining six long strips with square edges to make the panel top and bottom pieces. To do this, swivel your miter gauge to 12 degrees and cut six pieces for the panel bottoms to 5″ long. Cut six pieces for the panel tops to 1-1/2″ long.

Resetting miter gauge for making cut on lampe shade frame
Swivel your miter gauge to that angle, and trim one end of the square-edged strips to shape.

Use a stop block clamped to your saw’s rip fence to control the length of these long and short parts.

Using step-off block to guide lamp shade frame cut
Then use a step-off block on the rip fence to set the long bottom and short top part lengths.

And when you’re orienting the angled cuts on the ends of each bottom or top workpiece, cut them so the angles are facing one another. Finish sand all the wood parts you’ve made so far.

Panel Gluing and Clamping Jig

Diagram of lamp shade frame jig
The author used this melamine and MDF jig to set and hold side, top and bottom pieces in place when gluing up the shade’s six panels. One of the jig’s three sides consists of a wedged interface to provide progressive clamping pressure.

Gluing and clamping these side, top and bottom pieces together to form panels will be a lot easier if you use a simple jig. It consists of three fixed pieces of 1/2″ MDF that will form an outer frame around the panel when you assemble it. A wedged piece slides along one of the jig’s frame pieces to provide clamping pressure. I used a large piece of melamine as the base for my jig, because glue won’t stick to it. Cut three 2″-wide pieces of MDF for the jig frame parts. Bevel one edge of one piece to 29 degrees, and crosscut it 11″ long. Fasten this piece to the jig base with screws so its square edge is flush to one of the base’s long edges. Orient its beveled edge down so it will press a panel side down and flat when in use. Now miter cut the ends of a second MDF frame piece to 12 degrees, and make it 8-7/8″ long. Keep its long edges square.

Gluing up ends of lamp shade parts in jig
Spread glue on the part ends, and insert the panel workpieces into the jig. The bevels on the panel sides should engage the jig’s inner beveled edges.

Attach this frame piece to the jig with screws so one of its angled ends aligns with the same edge of the jig base as the first frame piece did and so it forms an angle with the first frame piece. The third frame piece I attached was the wedged clamping side. I first beveled the edge of this MDF frame piece to 29 degrees, then split the workpiece across its diagonal with the blade at 90 degrees to form two wedges.

Using wedge to hammer lamp shade part in place
Tap the jig’s adjustable wedge against the fixed wedge to secure the maple parts. Its beveled edge faces down to engage the panel side bevel.

Attach the wedge without the bevel to the jig base so the other wedge (with the beveled edge) can slide along it to provide tension against the panel parts as you glue them up. Cut and screw a cleat over the fixed wedge to hold down the sliding wedge during clamping. Then use your jig to glue and clamp two side pieces, a top and bottom to form each of the six panels. When you install the maple parts in the jig, face the bevels on the panel side pieces so they engage the bevels on the jig’s side and wedge. Gently tap the wedge into place.

Second Jig Combines Panels into a Shade

Installing lamp shade frame with installation jig
This second jig with six blocks will hold the six panel frames together for final assembly after the rice paper is installed. Prepare it for use with the six shade frames dry assembled and taped temporarily together.

Once the glue dried on my shade’s six panels, I created another quick jig from MDF that would be used to glue the panels together in an upright position. To arrange the jig’s six blocking pieces into a hexagon shape, I simply taped the panel frames together temporarily, butted the blocks against them and attached the blocks to the jig base with screws. I cut a shallow bevel along the inside edge of each block to improve its hold-down ability.

Ready to Install Rice Paper

Laying out lamp frame on rice paper to measure it

The best way to adhere the rice paper to the panels, I learned, is to use a mixture of wood glue and water thinned to the consistency of white school glue. I brushed glue onto the narrower (inner) face of each panel, making sure to not get any glue on the frame edges.

Snap blade knife used to trim rice paper
The author used a snap-blade knife to trim the rice paper flush.

I then carefully set the panel down onto flattened rice paper I had taped to a larger melamine surface, making sure there were no ripples in the paper. I found it easiest to place the bottom down first and then gently set the top down.

Cutting technique for trimming rice paper around lampshade frame
Cut the top and bottom first, then the sides. A slight sawing motion trimmed the extra paper off cleanly.

When gluing the panels to the paper, make sure they don’t sit too long, or the glue could soak through to your work surface. As soon as the glue tacks up, trim the rice paper overly large and turn the panels paper-side up. Allow the glue to dry for a few more minutes, then trim off the rest of the extra paper flush to the wood edges.

Final Assembly, Finishing and Hanging

Gluing together lampshade with framing jig
Spread glue along the beveled edges of the shade’s six panels, then install them in the blocked clamping jig to hold the parts in position. Here’s a job for a helper’s second set of hands!

When the paper joints are fully dry, you can proceed to glue the six frames together along their beveled edges, using the upright clamping jig and blocking to align and hold the parts in place. A second set of hands can be helpful for this step! Adjust the joints carefully as you position the six frames on the jig, and don’t overtighten the blocking pieces in case you want to make slight adjustments before the glue sets. After the glue on my lampshade frame joints dried overnight, but before I did any touch-up sanding, I sprayed a very light coat of aerosol lacquer to the inside and outside of the shade. I did this to help prevent any sanding dust from attaching to the rice paper. When that dries, sand the frame where you need to, and touch up any bare wood with more lacquer.

Hole for installing lamp shade screw mechanism

Every lampshade needs to have a support to hang from. For that, I used a simple 1/4″ x 1/2″ strip of maple with 21-degree bevels cut on each end. Drilling a slightly larger hole than the threaded post on Rob’s lamp harp, I was able to make a simple yet effective support for hanging it and wrapping up this project.
