Re: [PSUBS-MAILIST] Reverse engineering in CAD

[Peter McKellar <submckellar@earthlink.net>]

Hi Steve,

cursing helps :)  i find staring at the screen vacuously for hours (sometimes drooling and 'sleeping on an idea') helps too.

Alas, the design phase is expected to take at least 12mths.  I am fairly certain that my preferred material - acrylic, will end up being impractical, both for cost, fabrication and weight.  This will then force further changes to my design........

basically, don't hold your breath hahaha.  in fact you will need much more than 72hrs emergency air.

Question:  we all know that the laws of the sea say that when shipwrecked and drifting in a lifeboat, you kill and eat the cabin boy first, then work your way up the ranks.  Another option is everyone chops off a leg (in turn by rank again).  Is there a similar protocol when stuck on the bottom?  I was just thinking that 72 hours emergency air for two people is 144 hours for one.........comments?

note:  my wife says shes not going ANYWHERE with me hahahah :)

cheers
peter

Well, hey, that's a good idea, too !  Works for me.
"K.I.S.S."  It's all geometry and genius :-)  [ cursing helps, too ]
Looking forward to seeing what you come up with.

cheers, --Steve
