Hi All,
I
have just recently meet a potential new psubber just down the street from me
through my 11 year old daughter's playmate. Her dad has all the makings
of a sub enthusiast. (and he's going to maybe let me use some
of his equipment !! lathe, welders, mill..etc !! )
Anyway he was telling me about a process used in producing cylinders like
torpedo tubes where they are made perfectly round using a giant form that is
punched in the middle of a molten sheet of metal and stretched around
it. Then a some sort of series of rollers forms the cylinder into a
perfectly round shape. In this process there is no seam which is welded
long-ways down the cylinder.
If one could find some of these Navy surpluses cylinders that were the
right size, and the grade of steel determined, they might be able to be
used for a psub.
Does anyone know of this process? It may not be absolutly nessesary
for a psub but it really addresses that roundness issue.
