- The component parts of the otter boards, shown here with<br />
prepared otter board bars.<br />
Fig. 230<br />
- A jig is required for bending the four otter board bars 10.1<br />
to shape: hammer nails into the corner points as shown in<br />
the full-size drawing, and bend the wires round them as<br />
shown.<br />
- Slip the split pins 10.2 onto the otter board bars, and solder<br />
them in place.<br />
Fig. 231<br />
- The otter boards are assembled as a mirror-image pair.<br />
- Glue five strips 10.3 to each of the inner otter board frames<br />
10.4, and drill 1 mm Ø holes through the strips as<br />
shown.<br />
- Glue the outer otter board frames 10.5 on top. Cut back<br />
the wooden strips to follow the outline of the frames, and<br />
sand the cut ends smooth.<br />
- Shorten the split pins 10.2, and glue them to the otter<br />
board bars.<br />

- Make up the net hooks 10.6 as shown in the full-size drawing,<br />
and glue them in place.<br />

- Carefully lay the net fabric over the templates, smooth it<br />
out flat and press it down. Cut the top and bottom net<br />
sections along the outline of the templates, leaving them<br />
3 mm oversize.<br />
Fig. 238<br />
- Lay the net panels over each other, with the templates on<br />
the inside. Line up the outlines, and peg the sections<br />
together as shown in the photo.<br />
- Tack the net panels together at the corner points using<br />
thread.<br />
Figs. 239 and 240<br />
- Sew the net panels together using a needle and thread,<br />
working along the side edges and the bottom. Tie knots<br />
in the thread at intervals of about 1 cm; this prevents the<br />
net becoming pulled out of shape or distorted. <strong>Le</strong>ave the<br />
upper end of the net open.
