We are designing a seastead.  There are 4 floats that made of duplex stainless steel
and are like 4 foot diameter pressure tanks with dished ends.
The sides are 1/4 inch thick and the ends 1/2 inch thick.
The body (above the water) has some frame and some corrugated duplex stainless covering things (maybe 2 or 3 mm thick).
The floats are about 20 feet long.  The living area is about 16 feet by 40 feet.

If we wanted to purchase machines to make our own pressure tanks and the corrugated parts,
please give me an idea of the size of the building and the cost of the machines.
Look at two cases, say we wanted to be able to make 1 per week, and then also 1 per day.
Assume we want higher automation when it is available.
