hatch ring
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
