An easy to make Bench Seat
Wood you will need
Note: If you cannot source the stock sizes given below, slightly bigger or smaller will do. I used a softwood which required coating with a preservative for outside use. If you are able to get a treated wood or a wood naturally resistant to decay, all the better.
3/4" x 2 3/4" (20mm x 69mm) for the seat slats and back-rest slats.
(a) 13 pieces @ 48" (1200mm)
(a1) 1 piece @ 16 1/2" (412mm)
1 1/4" x 2 3/4" (32mm x 69mm) for the side frames.
(b) 2 pieces @ 23" (575mm)
(c) 2 pieces @ 24" (600mm)
(d) 2 pieces @ 31" (775mm)
(e) 2 pieces @ 21 5/8" (540mm)
(f) 2 pieces @ 25" (625mm)
You will also need:
Around one hundred 2" (50mm) exterior type wood screws, four 3/8" (10mm) galvanized carriage/coach bolts 3" (75mm) long, exterior type wood glue, wood preservative (if required).
You can get way with just a handsaw, electric drill and drill bits for the bolts and screws, a hammer, square, screw driver, measuring tape, pencil, a bit of sand paper, and that's about it.
