Brian,no didn't know you could cut it with a skill saw. Watch it doesn'tget hot & seize around the blade.Cheers Alan

Alan,             I like the idea of the ropes to control in case of rolling during a test.   BTW, got all that lead today, did you know that you can cut lead with a Skill saw ?   I just tried it today, works really good.  I think I might be able to position all that lead in my ballast area with out having to melt it .   I can secure it with some sort of bolted bar arrangement. Brian

Brian,so if you add weight you need to add floatation to counter it.When I first saw the video I thought perhaps fill the bottom ofthe cylindrical hull section with lead. Maybe pour the lead to the contourof the bottom & add syntactic foam around the conning tower.With the height of the conning tower that would improve yourcentre of buoyancy. Tritons top pilot told me he liked to dive as quickas possible due to the instability issues that Vance described withthe CG & CB changing. you may find that you aren't so top heavyonce the conning tower is under. Perhaps you could attach a ropearound the conning tower next attempt & limit any roll just in case.Cheers Alan

Hi Alan,   Going to add a lot of weight to the bottom of the concrete ballast , at the very bottom.  Need to cut an access hole in that area so I can put lead bars in there and bolt them in. Brian

Another interesting video Brian.I see what you mean about the stability.Pity you couldn't have sunk her completely to see how stable she was once that big conning tower was under the water.What's the next step?I am not sure I am getting all the posts so apologies if I'm doubling up on any one else's comments.Alan
