|| There is only one
frame which falls at the widest part of the hull. It's often easier to do
a full size layout drawing of the frame and set your wood on it. The final
measurment of the bottom and the side frame are 39" and 16". They have
to be slightly longer initially. How much longer depends on the actual
width of your stock. If your wood was miraculously exactly 1.5" wide then
we could trust our drawing which says they are 39 15/16" & 16.55"
before the angle is cut. But in the "real world" your stock might be 1
5/8" so just lay your wood on your drawing and transfer the lengths.
Clearly mark the center of the bottom piece to help with
I like to cut the side pieces a couple
of inches longer than 16", and trim them later. This allows me to
temporarily screw a piece of scrap 1x2 across the top to stabilize the frame
while all the fastening is going on.
|| . Here's the pattern for the gusset. You
can draw a full size pattern or do something like I did with these foam
board scraps. Just make two 6" legs and a 9.5" leg and connect
them to each other. Instant pattern! Place them on your ply and trace the
|| The gussets are sandwiched between the bottom frame
and the side frame pieces. (see drawing) Glue and nail the assembly, with
one 1 ½” SS deck screw in each corner where the frame members overlap
These are drain holes that are found in most
traditional boats, which allow water
to move freely from one side of the frame to the other. They are more
important in a larger boat where any water needs to drain to the bilge
|| I feel they are optional in this small a
boat since a boat this size is often turned over to empty, or bailed and
sponged. There are a couple of ways to make limber holes.
|If you have external chine logs, just saw the corners off
the frame. (See sketch.)
||They will need to be more inboard if you do inner chine logs. Notch for
inner chine logs before you attach the frame to the sides. (See sketch.)
|Whatever you do make sure you seal them well with epoxy or
paint prior to assembly. They are difficult to get paint to once once
assembled, and they could suck water into your frame and promote rot if
water is left standing in the boat.
