Tub
Let’s build the tub.
First, mark the insides of the tub right
and left. The sponson boom hole is
toward the bottom of the tub side.
Make these marks in the front portion of
the sides, where it won’t be seen later.
Check the fit of the bulkheads in the
right tub side.
Use a file to touch up the inside corners
on the bulkheads, to square off the tiny
radius left by the cutting bit.
Once you are happy with the fit of the
bulkheads in the tub side, glue them in
with CA. Use the square provided in the
kit to ensure each bulkhead is perfectly
square.
Make a mark on both tub sides (inside)
with a line that is an extension of the
transom cutout.
Use this line to align the transom
correctly on the tub side.
