questions about the acrylic dome
Cliff
Although they have been used on many subs for
many years, the dome of a K-250 is not to present day standards. It is a
free blown bubble blown in a 1/2 inch thick sheet. It's not a cast dome.
As a result of blowing the dome it is thinner then 1/2 inch at the top.
The outside radius is 12 inches.
There is no flange on the dome. It is just
a half sphere.

questions about the acrylic dome
Can someone with plans for the K-250 answer
some questions about the acrylic dome:
1) Is the dome an ASME/ANSI PVHO hemispherical
window with equatorial flange?
2) Dome outside radius ( Ro in ASME/ANSI PVHO
nomenclature)
3) Dome thickness ( t)
4) If hemispherical viewport with
equatorial flange, what is the flange width (M in ASME/ANSI PVHO
nomenclature)
5) Flange thickness
Thanks in advance.
