It will be like a port frame but with a 5\8 steel plate with a prop shaft tube weld to the centre with giant gussets. Normally I would weld in a ring that is several time heavier than it needs to be, but in this case I can not get crazy with weight. The weight is important because it is still an escape pod. I have sized the ring to be 20% heavier than the material removed from the sphere. I am assuming that the 5\8 plate that is bolted to the ring adds support to the ring. I realize the added plate is only as strong as the bolts securing it, but there must be a benefit, or does this not count? </div><div>Hank</div></div></body></html>
