According to fura-2 :
You're absolutely right. There will be a hole, and I forgot to take
this into account in my post. I guess in the worst-case scenario I
could configure things so that I could fill the hole with weld (if I'm
good enough).

Hmm ... you *could* mount the halves of a Greenlee punch in a
hydraulic press, and punch holes without a center hole. But they
*still* would come out shaped like a Pringles artificial (reconstituted)
potato chip. :-)

Enjoy,
DoN.
