Technical Information for Building an Wooden Planter Boxr

A. Materials List:

2 A Sides 1/2" x 6 1/2" x 11 1/16" Redwood
10 B Slats 1/2" x 1 3/8" x 18" Redwood
1 C Bottom 1/2" x 7 3/4" x 18" Redwood
4 D Screw Eyes 12 GA. X 1" Stainless Steel
1 E S-Hook .12 x 1 1/4" Stainless Steel
4 F S-Hooks .091 x 7/8" Stainless Steel

B. Cutting Procedures:

  1. Cut all pieces for this project from an 8" x 84" piece of lumber.
  2. Use a planer to plane the lumber to 1/2" thick.
  3. Use a table saw and a radial arm saw to cut out the sides (A), slats (B), and bottom (C), to the sizes listed in the materials list.
  4. Use a shaper with a 1/2" rounding over bit to route the top edges of the slats (B) and both top and bottom edges of the bottom (C). If a shaper is not available, a portable hand router could be used.

C. Sanding Procedures:

  1. Rough sand all parts with an orbital sander and 80 grit sandpaper.
  2. Intermediate sand all parts with an orbital sander and 120 grit sandpaper.
  3. Finish sand all parts with an orbital sander and 220 grit sandpaper after the assembly procedure.
  4. Hand sand all edges, details, with 220 grit sandpaper.
  5. Note: If a lathe is not available, you should be able to purchase the towel rod ends at a hardware store or a hardwood lumber store.

D. Wooden Planter Box Assembly Procedures

  1. Turn the sides (B) upside down so that the top edges are on the workbench. Clamp the sides with hand screw clamps to hold them in place. Place glue on the bottom edges of the sides and position the bottom (C) flush with the outer edges of the sides. Use a nail gun and 1 1/4" nails to secure the bottom to the sides.
  2. Rotate the assembly so that the edges of the sides are exposed. Use hand screw clamps to hold the assembly in place.
  3. Place wood glue on the edges of the sides. Position the top slat (B) flush with the top and outer edges of the sides (A), and nail the slat in place using a nail gun and 1 1/4" nails. Nail the other four slats in place. Be sure to position the slats adjacent to one another, to eliminate gaps. Also, use two nails in each end of each slat.
  4. Rotate the assembly so the other edge of each side (A) is exposed. Glue and nail the remainder of the slates (B) to the sides.
  5. Allow the glue to dry over night.

E. Finish Procedures:

  1. Use plastic wood dough to fill all nail holes, cracks and imperfections.
  2. Hand sand all edges with 220 grit sand paper.
  3. Remove all sanding dust with a wax tack rag.
  4. Apply boiled linseed oil with a brush.
  5. Allow linseed oil to penetrate the wood for approximately 10 minutes, then wipe clean with a clean white rag.
  6. Allow linseed oil to dry over night.

F: Attach Hardware:

  1. Screw the four screw eyes (D) into the top corners of the planter box.
  2. Place an S-Hook (F) in each screw eye.
  3. Make sure that the chain links (H) are all the same length. Place the other end of each S-Hook (F) through one end of each chain length.
  4. Place the S-Hook (E) through the other ends of the four chain lengths.
  5. Screw the screw hook (G) into a beam on the patio, or wherever you want the planter box to hang, and attach the S-Hook (E) on the screw hook.

*Congratulations, your wooden planter box is finished and ready to use!
