i can't imagine the nail heads supporting any weight. I think you
must rely on fiber to secure the algy to the plaster.
If the mold is slit on only one side, the other side must have some
kind of hinge. You can lay gauze right up to a vertical line, on
either side, and so avoid having to cut it. In fact you can make the
mold with gauze alone and use regular plaster to strengthen the
outside, and to form flanges at the 2 parting lines. That seems a
much easier way to work. Look at the torsos of Fred Reenders.
Don't fill the whole cavity with solid plaster unless you greatly
reinforce the mold. And why would you want something so heavy? You
probably mean to slosh several batches of plaster inside, with fiber,
until all sides are about 1" thick.
