Anything not explicitly spelled out is<br> subject to interpretation or disregard. I always<br> create completely dimensioned and toleranced engineering<br> drawings for this purpose, in addition to material<br> specifications and test performance requirements, and make<br> clear that if the part doesn't pass QC, the supplier is<br> responsible for correcting the problem. I get such an<br> agreement signed. Of course, I have the benefit of having<br> been doing this professionally for years. Strict hobbyists<br> cannot be expected to be as informed.<br> That said, I would take the required<br> tolerances, roundness, test procedures and so forth right<br> out of the guides, and present this when getting quotes so<br> that I get the true cost for what I need, and discover right<br> away if it is not within a supplier's capabilities.<br> How did your dome turn out? Were you able to<br> correct it?<br> Sean<br> <br> <br> <br> <br> On January 9, 2015<br> 7:29:44 PM MST, hank pronk via Personal_Submersibles<br> <personal_submersibles@psubs.org> wrote:<br> <br> Sean,<br> EE did my parts and my dome was quite bent when sitting on<br> the bench.

Sweet. Thanks Sean.<br> It's going to<br> take a syntactic buoyancy package to get it<br> right,<br> but it<br> looks like a decent alternative. A 6 1/2 foot<br> sphere displaces<br> about a thousand pounds more than the pair of 5<br> footers.<br> Pretty close, and might be marginally less<br> <br> expensive.
