answer to your question is yes,
but I don't have my Stachiw book
with me to see what the actual
rating would be. You can ask
someone else on the list to
check their Stachiw book, or I
will be back home around the
24th and can check my book when
I return. You obviously will
have less head room with a
9-inch depth. You also have to
make sure that they anneal the

have an issue in the
making of my k-250 dome.
I asked for advice from
some members in the past
and now I have a new
problem. The company
that makes my dome
cannot blow the dome to
the specs (12 in height
24 in wide). So the max
height that is
acceptable is 9in to
avoid the dome breaking
when it is formed. So my
question is ,is it
acceptable to have a
smaller height and I was
wondering if the
pressure rating of the
dome will be ok.</span></p>
