Bending Hull Strakes
Bending Hull Strakes: Put a small amount of ammonia (clear type, not lemon
scented! LOL) in the water (hold your nose!). Don't worry, the model won't smell
like cleaning fluid. The ammonia evaporates quickly. And use a fan for
ventilation. A water trough, like the ones used for wetting pre-pasted wallpaper
is great for this purpose. The ammonia helps, especially with sharper bends. The
plank section must be dry before gluing. I use a bending template jig (diagram
below) made of hard wood (with radii to match the different hull curves) to let
the sections dry, while gluing each preceding dry piece. Position a hair dryer
(on low) near the jig. Helps speed up drying time. The radii are slightly over
bent to allow for 'spring back'. Really sharp bends, or hard woods may need
steam bending. Wear gloves!

You don't have to follow the entire curve of the plate (s) with your plank
strip. You can just bend enough of the plank around a portion of the plate arc,
until you achieve the desired curve. The thickness of the plates is optional.
Don't make them too thin however (the planks may twist). 1/8" -3/16' thickness
is usually good. Generally, the larger the scale of the model, the larger the
scale of the planks, adjust the plate thickness
