[PSUBS-MAILIST] Wanted: Aluminum I-beam

[Cliff Redus via Personal_Submersibles]

Hugh can you send a larger drawing.  I can not see any detail in drawing.

There has been a lot of work done by ASME for  using standard pipe
components. I like your first plan.  Yes they are heavy with flanges and
bolts but all the parts are off the shelf and there is not an issue of the
design being sound in holding pressure.
