Next, mark the bevels on the bulkheads.<br />
Use a tick strip to transfer the bevel line<br />
as shown on the plans, or cut the bulkhead<br />
patterns from the plan and glue<br />
them onto the bulkheads. You can also<br />
lay the patterns over the bulkheads and<br />
use a pin prick to locate the bevels. Cut<br />
the bevels with a #11 hobby knife blade<br />
as shown (see figure 4).<br />
Some of the bevels are very slight, especially<br />
the deck bevels and the side<br />
bevels near amidships. These slight<br />
bevels are not drawn because they are<br />
hardly measurable. They can be sanded<br />
after the bulkheads are installed instead<br />
of pre-cutting them.<br />
Glue the bulkheads in place, making<br />
sure that the WL marks on the bulkheads<br />
and the center keel line up. Use a<br />
square to make each bulkhead perpendicular<br />
to the center keel, then tack a<br />
temporary strip to the top to hold the<br />
bulkhead in place while the glue dries<br />
(see figure 5).<br />
After all bulkheads are in place, tack or<br />
tape a temporary batten on each side of<br />
the hull just below the gun deck as shown<br />
(see figure 6). This is a critical step. Measure<br />
the spacing between bulkheads and<br />
retack the battens until the hull is aligned.<br />
Even though the center keel was assembled<br />
flat, it could warp out of line. The result<br />
could be that you wind up with a banana-shaped<br />
hull. Check the spacings between<br />
bulkheads, and port against starboard<br />
spacings. Look at the hull to see if it<br />
is properly aligned.<br />
When you are satisfied that the hull is<br />
aligned, check that the bottom of each<br />
bulkhead feathers out and lies precisely<br />
on the bearding line. Trim as necessary<br />
to line up. Also, check that the top of<br />
each bulkhead at the centerline is flush<br />
with the top of the center keel. Since all<br />
alignment is based on the WL marks,<br />
there could be some slight errors. Sand<br />
or add shims as necessary until the<br />
bulkheads and center keel surfaces are<br />
flush (see figure 7).<br />
