OK, the initial best suggestion was to add a relief hole to the
middle... duh! This worked, now I get the funny overlap at the last
two edges. Is this just a trial and error sort of thing? Do I just
tweak the angles till I get it right or is there a secret to it?
In the mean time, I am trying the make a pyramid, shell it, then rip it
method.
Thanx for the quick help.
