Dan,
The point I never considered was using
the rings to force the hull into roundness. I can definately see where
this would be easier when putting them on the inside as they could be pounded /
hammered / tapped into place, spot welded, and then secured when all was
well. That answers another question in that the rings are to be pre made
and not welded onto the pressure hull when building them. In that way, the
roundness of the rings could be made true before installing. As for
attaching things to the rings inside the hull, is it safe to drill 1/4" holes
for bolts or is that comprimising the integretity of the ring too much
? ...or would welding mounting brackets to the rings and then drilling the
holes be preferable ?
On the K350, does the design just
eliminate the ring where the tower is, the tower collar providing the strength
in that area ?
Thanks for making my mind up for me
Dan.
Myles.
