A coffee table is a coffee table... or is it? Why not have a fun, unconventional place to hold your books and coffee and—dare I say it—your feet? This plywood and copper coffee table can be bright and shiny or tarnished and weathered, depending on what your personal space requires aesthetically. There is no set pattern, so every table will come out a bit different. Need a bigger table? No problem! Build a second and third table and they will fit together like puzzle pieces. How many will you build?
Use a tape measure to find the midway point of the plywood along one edge. Mark it with a pencil.
Find the midway point along the opposite edge, and mark it, as well.
Use a straightedge to connect the two marks with a cut line.
With the cut line as your guide, cut the plywood in half with a circular saw.
Set aside one of the pieces for later.
Decide on the shape you would like your table to be, and mark angled cut lines accordingly on the first piece of plywood.
Using these lines, cut off all the excess with a circular saw.
Place the first piece of plywood atop the second piece and use it as a template to mark the new cut lines on the second piece.
Cut off excess with a circular saw.
Place one piece atop the other, and line up the edges.
Once you've aligned your two halves, screw them together with 1 1/4 inch screws.
Lightly sand the tabletop with an orbital sander and 220-grit paper.
The sides will be significantly rougher thank the top. Use an 80-grit paper to sand the sides until they are fairly even. Then, switch to 220-grit to finish-sand to full smoothness.
It should come out soft to the touch. You may also want to "break," or soften, the hard, sharp edges. This can be done with the orbital sander or with a piece of sandpaper.
Make sure your tabletop is sawdust-free before moving on to the next step, by wiping it down with a dusting cloth.
Apply one coat of polycrylic finish, using a applicator brush.
Once the polycrylic finish is fully dry, give it a VERY light sanding with 220-grit paper.
An orbital sander is fine for the tabletop, if you don't exert any pressure. Just let it glide across the top. The sides are better suited for sandpaper.
After ridding the tabletop of any new dust, apply a second coat of polycrylic finish.
The tabletop is now finished. Set it aside for now and move on to the copper legs.
Use a tape measure and a pencil to mark cut lines on the copper pipe.
If you have never used a tubing cutter before, the next few steps detail how it is done.
Line up the cutting wheel on the tubing cutter with the cut line you made in the previous step. Tighten the knob at the bottom of the cutter until there is a medium pressure on the tube. There should be just enough pressure where you can feel the resistance yet still rotate the cutter all the way around the tube.
Each time the cutter does a complete revolution, tighten the knob a half turn. You should see this scoring mark begin to emerge.
After several revolutions, the copper will break in two.
Shine the copper with a steel wool pad.
Apply the glue in a thick coating to the inside of the fittings before attaching them to the pipes.
As you connect the pipes and the fittings, give the pipe a couple turns in order to disperse the glue evenly.
Use eight pieces at 16 inches, eight pieces at 2 inches, eight 45° elbow fittings, and four 90° elbow fittings to assemble the legs, as shown here.
Use two pieces at 4 3/4 inches, two pieces at 7 inches, two T fittings, and connect them with a 12-inch long piece, as shown here.
Add four 90° elbow fittings to the ends and four 90° elbow fittings to the ends of one piece at 7 inches and one piece at 11 1/2 inches, as shown here.
Add the four legs to the supports.
Lay the tabletop flat on your work surface, bottom side up. Center the legs on the underside of the tabletop, as shown.
Attach pipe straps over the pipes, near the elbows and T-fittings.
Attach the straps to the tabletop with 1 1/4 inch screws.
Flip your table... and you're finished!
