Brian,
You'll also generate lead sawdust and some degree of  fumes.  Remember to 
take all the precautions with that.

Brian,
no didn't know you could cut it with a skill saw. Watch it  doesn't
get 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 of
the cylindrical hull section with lead. Maybe pour the lead to the  contour
of the bottom & add syntactic foam around the conning tower.
With the height of the conning tower that would improve your
centre of buoyancy. Tritons top pilot told me he liked to dive as  quick
as possible due to the instability issues that Vance described with
the CG & CB changing. you may find that you aren't so top heavy
once the conning tower is under. Perhaps you could attach a rope
around 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.

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
