[PSUBS-MAILIST] making progress

Looks good Brian, nice tool.When I test, I always pull a vacuum to ensure there is no hatch leak and it ensures there are no other leaks.  When I tested my escape pod there was nothing holding the hatch but vacuum.   Hank

 Hi everybody,                            Finished making a cutting tool for making 1" concaved hemispheres into aluminum for the ultimate purpose of making aluminum molds for 1" lead balls .    Finally acquired enough lead to sink my boat now !!   My plan is to weight it per my best guess for level from fore to aft.  If I'm off and the nose is high or low I will shift weight or add weight in either the bow or astern.  Since I can flood the ballast tank from outside the boat I should be able to get the whole thing balanced before I actually am inside the pressure hull.   My goal is to balance it out with just the top part of the conning tower exposed.  That would be with the ballast completely flooded, then I'll have a inside bladder that I can use to add the few extra pounds to take me down.  Will probably secure the hatch additionally with a strap from the outside just in case some water wants to get in there before there is enough pressure on the hatch really seal it good.  Also am ordering the additional axel for my trailer so I can safely haul this beast. See hemisphere drill below: ,  decided to put a Morse taper on the shaft that way I can create molds on the lathe using aluminum round stock. Brian
