[PSUBS-MAILIST] SeaQuestor progress.

[David Colombo via Personal_Submersibles]

Hi Rick, use aluminum flashing that you buy from the hardware store as the
form cut to shape on both ends of the foam block. Draw your hot wire across
the form, and you can get the exact shape. Play with voltage on your hot
wire to determine the speed and smoothness of your cut.
I will be doing the same thing for ballast tanks to fit around my external
ribs under the exoskeleton.
