I decided to engineer a new box for my outback for the rear 8" hatch since it doesn't get used for anything else. I was using the dry bag method up to now.

All that's needed is a CNC router, Hand held router, table saw, 1/2" and 1/4" ABS plastic, ABS glue and some basic dimensions.

Directions;

For the rounded part; Program the router using master cam, load drawing into CNC machine operating software. Adhere the 1/2" sheet of ABS to the router. Push the go button. Wait a couple minutes, remove plastic from router.

(The round hole in the top serves two purposes; one is to route the power cable, the other is a finger hole to lift it out.)

Cut squared pieces to proper dimensions using the table saw.

Glue it all together with ABS glue. Let sit for 24 hours to cure.

Use the hand router to round off the top edge of the box.

The box should fit any Hobie with 8" round hatches.

The battery I use is a 12 volt, 14AH. Slightly larger than typical but I can run my FF/GPS for about 3 days without a charge if necessary.

If you use a typical battery with the box I made, you can put your keys and wallet in it too.
