blind riveting the sheet aluminum to the aluminum tube ribs?
Thanks again.
Shouldn't need many rivets. I'll leave it to guys like Frank and Joe to give a more-knowledgeable assessment, but it sounds good to me.

Standard practice on the Fly Baby is to install ~0.025" gutter flashing across the front of all the wing, horizontal stabilizer, and fin. For more of an antique look, Kurt Gruber left it off the vertical tail:

You can see this plane with the stock metal under the fabric Note that the fin ribs are almost invisible in comparison:
