Hi Brian. Did you see the pictures that Wilifred had here of his concrete
submarine? I was really impressed with the size and especially the shape. Quite
an achievement.
As to the voids, a vibrator is the only way I know of to get out the
bubbles, regardless of how you form it up.
In the thread, he mentioned compacting the concrete. I don't know what that
means. If you are seriously considering making a concrete sub, ask him for
advice, sounds like he knows what works.
I got confirmation yesterday from the steel shop about my sub hull parts.
They are shipping on the 28th. I'll be posting pictures when I start assembling
them. Good luck on your project. Frank D.
