After creating full size templates
for the 10 stations and 2 stems, I managed to squeeze them onto a single
4x4 foot piece of 1/2" BC plywood, and then contact cemented them as shown
here. |
 |
The stations and stems were then
rough-cut into sizes manageable on the small bandsaw. |
 |
All cuts were made outside the
lines, awaiting the disk sander to trim all stations and stems to the
proper shape. This assured a fair degree of accuracy without a lot
of finesse at the bandsaw. (No "Norms" here . .
.) |
 |
Here the pieces are trimmed to final
shape using a small disk sander. It is easy to follow the lines when
cutting proceeds at a very controlled pace. |
|
|
 |
Ten stations cut to their final
dimensions, with the centerline and sheer lines marked on the forms.
The bow of the kayak starts at the rear stackup of
stations. |
 |
This construction is approx. 1/3 of
the strongback, the 17' long guaranteed straight building adjunct that the
rest of the project will revolve around. We build two 6"x7"x8' boxbeams,
and tie them together with a smaller boxbeam that will seat inside and
allow for overall length adjustments for the entire strongback
assembly. |
 |
One means for attaching the
strongback to the legs is shown here - I have built a horizontal member
that will contain the cross-section of the strongback and attach to the
leg assembly, yet to be created. Two of these are necessary, as are
two sets of legs. |
|
|
 |
Both 6" x 7" x 8' box beams are
complete, resting on the new leg sets. I don't think I'll use
staples in the kayak, all of these forms have been done without fasteners,
except where it must be a removable assembly. |
 |
Here I'm making the last 5" x 6" x
4' boxbeam to tie the two larger beams together and allow for some length
adjustment. This shows the internal forms that keep the box beams
from turning into parallelograms. |
 |
A small clamp farm is handy to have
if you want to work without the use of fasteners. I used carpenter's
wood glue for these fixtures, and a clamp time of 30 mins.
Time to cut & prepare the pieces for the next
task. |
 |
Finally a completed
strongback. I temporarily need the box beams to help build a long
guide board setup for ripping the cedar strips. That means I can't
mount the stations to the strongback until I rip the
strips. |
