[PSUBS-MAILIST] gamma ballast tanks

[hank pronk via Personal_Submersibles]

Scott,
I just posted a picture of Gamma with the new unpainted ballast tanks.  The tanks cost 130 dollars each inc shipping.  If I had a K350, this is what I would do.
Your new sub has 3 front ports, so it is a perfect fit.
I would confirm the dimension of that sphere because they say the actual volume in cubic inches and that works out to 139.85 net lbs in fresh water but at 24 in it is 205.72 net lbs in fresh water.
