[PSUBS-MAILIST] Concrete Sub Hybrid



Hi Brian, 

I can understand the confusion since I just recently figured that one out. ;)'   I didn't ask about it, since I figured you had explained it in the list at one point, and I planned on going back and seeing what you had said. 

I think I might of finally figured out a way to make my Batic THUWG go vertical either nose up or nose down when fully submerged. But I think I might just add that feature on the second one (if it gets built) to keep things simple(er).  Why you ask would I want to make the sub go vertical when submerged. Well because it's fun would be the shortest answer.  What's good for a reed fish is good for me.  Dancing with whales will be a blast.

Regards,
Szybowski

Frank, Technically my sub is not really a concrete sub, it's a hybrid.  Only the main ballast, which is for surface transit, is made out of concrete (ferro-cement).  The rest will be steel.

Hi Brent. Your sub was built a long time ago, and I'm sure the available paints have gotten better since then. The grey paint is probably a zinc rich coating if it's still in good shape after all these years. I have some paint called "zincalate" that we used all the time when I was working and it lasts many years. I have a friend who used it on a small metal ladder for his live aboard sail boat, and it was still good after 5 years, submerged in salt water for long periods. It's not cheap, but works. Will you be doing your own sand blasting? I'm not at that stage yet, but will probably rent a blaster when the time comes. Brian from Ojai may want to get together with us when you visit. He's building a concrete sub. Frank D.
