RE: [PSUBS-MAILIST] Nuytco sub observations

[Alex <spm2@nomad.ignorelist.com>]

It looks like that spehrical section is both pressed and welded. That's the
best of both worlds. The spherical end is not too big to where metal thinning
is a a problem. And the welded sections look like they were made on the same
press to match the same sphere. That way everything fits together perfectly,
and only a few sections are needed!
