Hi,
I just started thinking about the idea of doing a
preliminary pressure test on my hull (when it's made)
by fitting a vacuum
pump to the outside. This would be done on the bare hull but with the dome view
port in place.
I would need to have a negative pressure of 250
psi.
Does this sound reasonable? Are there cheap vacuum
pumps that can produce this negative pressure or are there
air pumps that I could modify & attach the
intake to the hull ???
Or has anyone done this?
Regards Alan
