I'm hunting for a specific sized enclosure for an upcoming project, and so far the usual surplus suppliers haven't yielded any luck. I've checked Alltronics, All-Electronics, Hosfelt, and MPJA (they have a few 'maybe' enclosures, but they're spendy).
I'm looking for something either very light weight aluminum, or plastic. It needs to be a design capable of being waterproofed, and roughly 5.5"x5.5"x3".
Anybody have a favorite source for this sort of thing?

D'oh .... I read feet instead of inches
I sometimes make enclosures by soldering together pieces of double-sidded copper-clad pcb material...very strong, electrically conductive/emi screen, easy to cut/drill etc. When constructed clean and buff, add any artwork then spray with a coat of pcb laquer to prevent tarnishing
P.S. you can also use the inside walls for heatsinking or mounting circuits 'ugly' or 'Manhattan' style.

You live in United States, so do I. Go to Lowes and ask for scraps of plexiglass. Then cut that with a tablesaw or score with a kitchen knife and break. Score many times over the straight edge and break on the edge of the table, while pressing down with a board to keep the breaking line from bulging up. I have a whole tecnique for this kind of cheap production I can tell about.

Have you checked craft stores? They usually have some nice small wooden boxes. It's pretty easy to waterproof them too, some polyurethane and a rubber band gasket works just fine.

Wood is definitely not going to work in this case. Too heavy, to easy to damage, impossible to genuinely waterproof.
Plexiglass would be too heavy and too easy to break. This will be for my portable ham radio during my upcoming hike.
If I have to fabricate the box, it will be done by creating a mold and using high pressure injection molding (I have access to tool & die shop) and some kind of highly impact resistant plastic like ABS.
I'd much rather go with a purchased enclosure though, much cheaper, easier, and faster.
Anybody got a favorite surplus place that specializes in enclosures?

Dave,
Thats simple. If it just needs to be waterproofed, just get a small waterproof utility bag like the kind they store equipment in during scuba diving or other outdoor sports.
Lightweight, cheap, and 100% waterproof.
Maybe even a underwater point-and-shoot camera bag. They small and cheap.
