Brian,
I think you're fine as is. The one that's
really nice to have in stainless is the ring that your hatch lands on, because
in getting in and out you scratch tha paint very easily there. But that said,
all the home built subs I've seen so far have steel lands due to the cost of a
large stainless ring. The "pro" subs have SS there, we just
repaint.
rgds,
Alec
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:
Thanks
Brian
