Would the refraction index make it hard to see forward out the
windows. They have to be more perpendicular to the line of
sight.

Hi guys. Man
it's cold out there. I think I'll go into town and buy some steel instead
of braving that shop today. Anyway, back when I couldn't make the
connection with the tank heads I needed, I started redesigning something I
could make from parts I could get easily. Fortunately I was able to get
the heads, but I came up with this design for a cheap and lightweight sub.
It obviously has some shortcomings, but because it's so compact, could be
something less complicated if a guy wanted to go relatively shallow on a
limited budget. Take a look and see what ''cabin fever'' produced. Frank
