Gas/RCABS Hybrid
I still have my kilo in the works and a Seawolf in the closet. Both utilize the 2" SD with gas ballast system. I was thinking of adding a snort system to minimize gas use. I managed to salvage a micro airpump from a friend's broken digital sphygmomanometer . The only problem I see with the airpump is that it lacks the induction tube connection nipple. Air enter the pump through small holes on top of the pump. These holes a sealed by flap seals. I can still use it as a snort system, but the induction tube would connect directly to the inside of the sd so I'll need to use a float valve to seal the sd once the sub dives.
After some pondering I realized that the pump I have is similar to what RCABS submariner use. I was wondering if it would be possible to make a gas/RCABS Hybrid instead. Looks feasible but would the shaft and control seals on the SD Be able to handle negative pressure induced by the pump?
