On the Little Joe II build threads (either here or on TRF, I don't remember which) George or James illustrate using a dowel sandwiched between the fin halves to form a tab to glue into the body. I thought that rather clever.
I have a set of the Saturn V fins and like pictured on the Estes site, they are two halves glued together like LJII so adding a tab should be straight forward. |
