You might use them as forms to build your own home-made octogonal sound boxes of what ever depth you are wanting. Here are a couple of links that on CBN that may inspire you...

1. The 'Bird's Mouth Mast' Method of Making an Octagonal Sound Box or ...
2. Building Round Sound Boxes for Banjos

The first link talks about how to create an octagonal box frame by making 45 degree cuts (easier to do than 22.5 degree cuts) and is pretty interesting method. It was adapted from the mast making trade (mast for old time sailing ships). A belt sander is used to sand off the little extra bits of wood that remain after the glue-up.

The second link builds an octagonal frame and then rounds off the corners with a stationary belt sander to yield the round frame needed for a banjo. It includes the math for calculating the size of each trapezoidal block that will for the octagonal frame.

Hope this helps.

that is exactly the boat shelf  Iwas talking about. They are out of stock atm, so maybe my next build :)

Im pretty excited about the trays, I ordered a second set so I can make the larger ones deeper and louder for acoustic play.

I may need to have my own corner hardware cut.

CB Gitty sells box hardware (including corners and hinges) http://www.cbgitty.com/box-hardware/
Searching on google or eBay for "flight case corners" often comes up with interesting corner protectors - I think it would be difficult to get them to reshape to fit the octagonal tray though.
I recall another member built a "Boatar" http://www.cigarboxnation.com/forum/topics/boat-load-of-fun-on-newl...

This will be an interesting project to follow.
