Shoulder bolts are certainly an option.  I was hoping somebody here had 
experience with hinge rivets (not riveted hinges) so I could determine 
if it was something I wanted to mess with.  I'll probably only ever make 
one tool box like this.  An extra half hour or so probably doesn't 
matter for just one, but the knowledge, tools, and skills may be useful 
for other things.
