I'm making an eight-foot study model of a personal lifting body
dirigible design of mine. I believe the ribs will be made of
fiberglass and widely-spaced for lightness. I want the skin to be
aluminum sheet.
It would be desirable to avoid installing a rib for every seam
between sheets of aluminum. So, I would like some advice on what is
the state of the art with infallible glue joints between hard aluminum
sheets.
I imagine there is no alternative to crimping the meeting edges as
is done when sewing two sheets of cloth together.
No way am I interested in rivets.

How about using sheets that are half as thick as you need and then glue them
on top of eachother with full overlap? I've used some 3M aluminum glue that
is stronger than the metal itself..
