[PSUBS-MAILIST] Question for the group

[hank pronk]

Graham,
You didn't mention if you are mounting these tubes horizontal or vertical.  If they are vertical, disregard what I said.

 Hi  
 
 Has anyone experimented with a different variable ballast
 tank I am thinking
 of making a tube of gas pipe which is made of thick plastic
 inside I plan to
 fit a bellows air bag, this will be blown up by the air line
 which blows the
 water out of the steel ballast tank . One end of the tank
 will be fixed so
 as to hold the bellows in place the other end of the tank
 will be drilled
 with holes to allow the water to escape and the bellows to
 expand. The
 pressure will blow the air out of the bellows when the
 return vale is
 opened. This method also eliminates the fear of what the
 inside of the steel
 ballast tank is doing due to sea water corrosion.  Has
 anyone any views as
 to why this method will not work.

 A club designed sub "OSS - Open Source Submarine" was
 attempted years 
 ago.  It had a good start but stalled soon
 afterward.  That kind of 
 project is difficult to complete unless someone with a clear
 vision and 
 desire to lead the effort takes charge of it.  I don't
 think I have it 
 linked from the main site anymore but the page still exists
 at 
 www.psubs.org/oss if you want to look at it or revive it.
 
 Franks saucer sub was taken over by his daughter.  Her
 intent was to 
 finish it and she did write into PSUBS shortly after Frank's
 death 
 notifying us of that intent, however I have never heard back
 from them 
 again and don't know what ultimately became of the sub.
