So theoretically there is some number of radial ribs that above this number, the head would reach a deeper max depth. Hi Cliff.
I understand a little better now the way the stress is applied on the
heads. I saw the knuckle stiffeners on Carsten's post too. Lots to consider here
before I fire up the torch and start wacking stuff out.
I wonder if increasing the hull thickness around the window sleeves and
hatch would be of any use. I could add 1/2 inch plate to the exterior without
cutting out the whole sleeve assemblies.
Because the head's "knuckle" area is the weak point it would be fairly easy
to add a bunch of radial stiffener pieces to that area on the inside. Even if
they were only 6 inches apart around the perimeter. Looking at the main
window assembly with a more conservative eye, it now looks kinda weak to me.
That's why I'm considering replacing the whole assemblies with thicker
sleeves.
