PLANS FOR A SWIMMING RAFT
These instructions describe the materials
needed and guidelines for building an 8'
x 12' (2.4 m x 3.7 m) swimming raft. The
materials needed are shown in Table 3.
The plans for the raft are shown in Figure 5.
CONSTRUCTION STEPS
1. Following the illustrations, create the
framework shown in Figure 6. With the
frame structure upside down, nail on
the four cross ties and the four skirt
boards.
2. Cut the three STYROFOAM ™ Brand
Buoyancy Billets in half for the six
shorter pieces shown in Figure 7.
3. Consulting Figure 7, lay the sections
of the STYROFOAM ™ Brand Buoyancy
Billets across the cross ties. Place
skids on the foam as shown. To
connect the foam, drill six holes
through the skids, foam and the cross
ties. Insert the long bolts and reach
under the cross ties to apply washers
and nuts.
4. Turn the structure over and tighten the
nuts to a snug fit.
5. Install lengthwise bracing first, then
install cross bracing.
6. Consulting Figure 4, nail on deck
boards using a piece of 1/2" (13 mm)
plywood to space boards 1/2" apart.
