Materials
One 4- by 8-foot sheet of 3/4-inch AC plywood
Twelve 1 1/4-inch wood screws
Primer and exterior paint
Tools
Tape measure, straightedge or carpenter's square, pencil, coffee can with 4-inch diameter, safety glasses, leather work gloves, jigsaw, 100-grit sandpaper, vibrator sander or sanding block, file, electric drill, paintbrush
Getting a 4- by 8-foot sheet of plywood home from the lumberyard may be this project's most challenging step. Rather than wrestle with it whole, have the yard cut 3 pieces from it:
One 24- by 48-inch piece (call it Section A) for the tabletop , One 44 1/4- by 48-inch piece (Section B) for the legs, tabletop support and cleats, and carrying clips, One 27- by 48-inch piece (Section C) for the seats and seat supports
If you want to save sawing time later, you can have the yard cut Sections A and B, plus the two 8 3/4- by 48-inch seats and the two 4 3/4-inch by 48-inch seat supports.
Tips for Cutting, Sanding and Painting Plywood
1. Once you've drawn the straight cut lines, use a coffee can with a 4-inch diameter as a template to round off most of the corners, lay out the handles, and shape the feet. Use a dime to round off the slots in the table legs, as shown on the diagram for Section B.
2. Use a jigsaw equipped with a sharp wood blade that will allow you to make both straight and curved cuts. Support the plywood on a stable work surface, cut slowly, and let the blade do its work.
3. The most important cuts will be the 3/4-inch-wide slots for the interlocking joints. See the Tip in step 3 on page 98 for an easy way to keep the measurements and cuts as precise as possible. During assembly, you may have to use the jigsaw or file to widen some of the slots for a smooth fit.
4. Wear safety glasses so you can watch the blade and your guidelines. Try to make smooth, continuous cuts to minimize sanding later. Wear leather work gloves to avoid getting splinters.
5. After you've cut your pieces, sand and round over all of the edges using 100-grit sandpaper, preferably on a sanding block or vibrator sander. Pay particular attention to the tabletop, seat edges, and handle cutouts.
6. When it's time to paint your picnic table, first apply a coat of quality exterior primer, then finish with 2 coats of exterior paint.
Now onto the building!
2. The football-shaped handle is a plus if you plan to carry your table often; otherwise, it can be omitted. Mark the handle with the coffee can (as shown at right), centering it horizontally on the board, then drill a 3/8-inch starter hole within the football. Make smooth cuts so the handle will be comfortable to grip.
3. Draw a line down the middle of the board (2 feet from each side)--this is not a cut line, but will serve as a handy reference point for marking the pieces. Mark the cutting lines as shown, again tracing around the coffee can. Darken the cut lines as indicated (in red) to create the curved edges and semicircle handles.
4. Cut out the piece of wood reserved for the tabletop support cleats and carrying clips. Mark and cut out the cleats as shown in the diagram below.
6. Cut out table leg 1 and use it as a template for table leg 2. Again, use the cleat to make sure the width of the slots is exact. Finally, cut out table leg 2 and the tabletop support.
TABLETOP SUPPORT CLEATS
Measure and mark the four tabletop support cleats from the center line
(here, also a cut line) and cut them out. Reserve the end pieces for the
carrying clips.
7. If the lumberyard didn't do it for you, mark and cut the two seat pieces and two seat supports, as shown.
8. Use the coffee can to round off the corners where indicated. Then use a cleat to mark the width of the various slots.
10. To ensure a snug final fit, position the cleats so that each pair sandwiches the tabletop support and the short ends butt up against the inside of the table leg. Screw each cleat in place with three screws (pre-drilling may be necessary).
