[PSUBS-MAILIST] Gamma test apparatus

[hank pronk via Personal_Submersibles]

Today I built a frankenstein looking  auto surfacing device.  I have a simple mechanical timer rigged with electrical contacts.  I have an electric gear head motor connected to the timer.  The motor has a cam mechanism that actuates a HP air valve that supplies air to the MBT's .  If this system fails, I still have my 5\16 "string" connected to raise the sub.Hank
