WOODWORKS: INTERMEDIATE PROJECT 2008-2009
MODULAR PLANTER BENCH
The beauty of this modular system is that it can be as short or long as you like; it can be straight, or it can take hard lefts or rights to follow the
footprint of a deck or patio. And, best of all, it’s simple, quick and inexpensive to build. You’ll be “up” and sitting in a few hours.
In this intermediate-level project, you’ll gain experience in making precise crosscuts and miter cuts and in doing an equally precise assembly.
And after you build it, you’ll learn more about applying and using finishes to protect the wood and keep it looking beautiful.

BEFORE YOU BEGIN
Good craftsmanship begins and ends with good work habits, so make
the following steps part of your routine workshop practice. If you have
any doubts or questions about how to proceed with a project, always
discuss them with your shop instructor.
• Carefully and fully review plans and instructions before putting a
tool to the project lumber.
• Work sensibly and safely. Wear safety goggles when doing work that
creates flying chips and sawdust; wear the appropriate respirator
whenever making sawdust or working with thinners or other solvents.
• At the end of every work session, clean up your shop area and put
away all portable tools.
Bench
8.
Cut the bench boards (G) to length and cut the corners (as shown
in Fig. 1). Rip parts H and I from stock left over from the 1x8 or from
scrap. Cut them to length.
9.
Position and install the guide cleats (H) (as shown in Fig. 4).
Use a scrap of 1x4 plus pieces of cardboard to determine the spacing
and ensure a loose fit when the bench is set on the planters. Use glue and
the 1-1/4" screws to secure the cleats.
10.
Position and install the trim strips (I) with glue and the 1-1/4"
screws. Sand all edges to soften sharp corners.
CUTTING AND ASSEMBLY
PROCEDURE
Planter boxes
1.
Cut parts A, B, C, and D to length. Rip part A to the required width
from 1x4 stock. Rip the four wide side pieces to the required width
(5-1/2") from 1x8 stock. (Note: parts H and I will also be ripped from
this stock, or from scrap.) To speed the job, clamp a stop block to the
fence so you can quickly make repeat cuts without measuring every
piece. Rip part A to the required width. (Note: Parts dimensioned
as 1x2, 1x4, etc., refer to nominal dimensions. The actual size of a
1x2 is 3/4" x 1-1/2"; a 1x4 measures 3/4" x 3-1/2".)
PROTECTING YOUR PROJECT
Any type of wood that’s used outdoors needs protection from water
damage. There are a variety of protective coatings available, including
clear and tinted wood protectors and semitransparent and solid stains.
Each of these finishes has a different look and maintenance requirement.
To provide complete protection for your project, use Thompson’s
®
WaterSeal
®
Advanced Tinted Wood Protector or Thompson’s
®
WaterSeal
®
Waterproofer Plus Tinted Wood Protector. Both products not only
prevent water damage, but also resist damage from mildew and
ultraviolet (UV) radiation in sunlight, and they exceed industry
standards for waterproofing on wood. Plus, the transparent tint will
give plain pine just the right amount of rich wood tone. These products
are available in five beautiful sheer wood tones.
2.
Drill and countersink pilot holes through the inner frames (A)
corresponding to the spacing of the side pieces (B) and using two
1-1/4" screws for each end of the boards to minimize cupping (Fig. 2).
Use scrap to cut 1/4"- and 3/8"- thick spacers to ensure even gaps
between the side pieces. The 3/8" spacers go between 1x4s and 1x6s,
and the 1/4" spacers are for sides that are all 1x4s. Your goal is to
make each space on a given side the same. Check this dimension
before cutting the spacers.
Woodworker’s Tip: Always be sure to choose a waterproofer that
claims to exceed industry standards for waterproofing on wood.
FINISHING TIPS
• Coverage: The approximate coverage of Thompson’s
®
WaterSeal
®
Advanced Tinted Wood Protector and Thompson’s
®
WaterSeal
®
Waterproofer Plus Tinted Wood Protector on pine is 200 square
feet per gallon.
• When you apply Thompson’s
®
WaterSeal
®
Advanced Tinted Wood
Protector or Thompson’s
®
WaterSeal
®
Waterproofer Plus Clear
or Tinted Wood Protector, do not mix it with other waterproofing
products, because variations in the final appearance of the surface
being treated may result. Also, do not thin these products.
3.
Start fastening the side pieces (B) to the inner frames. Apply glue to
the surfaces that will meet the frames and arrange the pieces so they’re
square to the inner frame. Drill shallow, 1/2"- deep pilot holes into the
side pieces through the existing holes in the inner frames and drive
1-1/4" screws into the holes. Fasten the sides to one frame at a time;
repeat the process for the second frame.
4.
Glue and fasten the floor pieces (C) to the top of the lower
frame, again using four screws per board to minimize cupping.
Use the 1-1/4" screws.
Recommended Finish
11.
Before applying Thompson’s
®
WaterSeal
®
Advanced Tinted Wood
Protector, the wood surface must be free of all dirt, wood dust and con-
taminants. This product can be applied to damp, freshly cleaned wood.
If the wood needs cleaning, use Thompson’s
®
WaterSeal
®
Deck Cleaner
& Brightener or Thompson’s
®
WaterSeal
®
Deck Wash. Read and follow
the directions found on the back of the can. After the cleaning is done,
read and follow the directions found on the back of the can of the Tinted
Wood Protector. Then do a trial test before full application. The surface
may darken slightly with application and color appearance is different
when the wood is fully dry.
5.
Glue and fasten the feet (D) to the underside of the box
(as shown in Fig. 1). Use the 2-1/2" screws.
6.
Rip the top trim pieces (E) to the required width from 1x4 stock.
Cut them to the actual length required and glue and fasten them along
the top edge of the box (Fig. 1).
7.
Cut the top frame pieces (F) to the actual length required. Use glue
and the 1-1/4" screws to join the corners and make the frame. Then
glue and nail the frame onto the top of the box with 6d galvanized finish
nails. Set the nail heads below the surface and fill the holes with wood filler.
After the filler dries, sand the top so the miter joints are smooth (Fig. 2).
12.
When applying this product, do not use it with other waterproofing
products, as variations in the final appearance of the wood may result.
Do not thin. To ensure good penetration, do not apply in direct sun-
light or on hot days. Do not apply if rain is expected within 48 hours.

Also, temperature must be above 50º F. and remain above freezing
for 24 hours.
NOTE:
The length of protection will vary depending on environment.
Perform the following splash test once a year to see whether
reapplication is necessary. Sprinkle water on various sections of surface
to be sealed. If water absorbs and darkens color of substrate within
5 seconds, the surface is porous and considered ready to be treated.
If water beads up or otherwise sits on top of surface, then surface
doesn’t need protection at this time. For maximum protection from
color change and other damage caused by the sun, reapplication is
recommended every year. Vertical and horizontal surfaces will
experience color changes at different rates.
13.
Shake or stir contents for a minimum of 2 minutes before use.
Intermix all containers (of the same color) to be used to assure
color uniformity.
14.
Use a paint pad or brush to apply, do not use a roller. For small
projects, a brush is the preferred applicator.
15.
Apply only one thin, even coat. DO NOT APPLY A SECOND COAT.
A heavier or additional coat will not improve performance or
appearance. Avoid puddling. Tackiness will result if overapplied.
Tackiness may also occur after application if overnight temperature
falls below 50°F. within 48 hours of application. Drying time will
vary depending on wood surface and humidity. Allow a minimum of
12 hours before using the bench.
PRODUCT SAFETY
For your safety and the safety of those you work with, always read the
safety warnings, which manufacturers print on their labels, and follow
them to the letter. Typical safety advice and instructions will contain
information such as the following:
WARNING!
Removal of old paint by sanding, scraping or other means
may generate dust or fumes that contain lead. Exposure to lead dust or
fumes may cause brain damage or other adverse health effects, espe-
cially in children or pregnant women. Controlling exposure to lead or
other hazardous substances requires the use of proper protective
equipment, such as properly fitted respirator (NIOSH approved) and
proper containment and cleanup. For more information, call the
National Lead Information Center at 1-800-424-LEAD (in US) or
contact your local health authority.
16.
Brushes and equipment used for water-based products must be
cleaned with soap and water; brushes used for oil-based finishes must
be cleaned with mineral spirits. Dry product can be removed with
mineral spirits.
