Riveting work

As a child, did you ever make one of those intercoms with two cans and a piece of string? Neither did Bub. Or at least that's not what he's up to in this picture.
He was listening though, for Gabe, who was inside one of the twin schooners as the two of them worked to fasten the hull planking to the frames.
As you'll see below, the planking is fastened in two ways: in the case of the double-sawn Osage Orange frames, it is done with large silicon bronze screws. In the case of the steam-bent frames, made of White Oak, they are fastened with copper rivets.
