When I put together my domed hatch ( in my machining class) I first
had the hemisphere fabricated and then I had a 2" ring welded to the edge of the
hemisphere. At the time I was not really clear
on how everything was going to come together and now in hind sight I
realize that the 2" ring that I welded on should have been stainless
steel instead of what I used.
My question is, can I fabricate a stainless ring and
connect it to what I have now ? I could remove some of that
material ( the ring part ) which is 3/4" thick so as to reduce the
weight. I'm afraid if I don't make that ring part thinner the hatch will
be too dam heavy.
If I do add this new stainless ring should I just weld it to the existing
ring? and then put it in a giant lathe and machine it true?
Here is a picture of the hatch cover:
