Right, so I can't find the original thread where I first started this project, so, I'll collate the images in this thread.
The design spec:
1 - waterproof tank bag
2 - slash proof
3 - lockable
4 - needs to carry my camera, wallet and a few other odds and ends
Now, by lockable, I wanted a bag I could lock as well as that it could be locked to the bike.
First came the cardboard mock up:
Next was how to mount to the bike, so I went with a fuel cap ring mount I found online and modified it. You can see it here with the aluminum cross bar I made. This mounts to an aluminum mount using the two front gas tank bolts. It also articulates upwards to allow access to the fuel cap.
The next mock up I carved from foam - literally three layers of pink insulation glued together, then carved to roughly the shape I was trying for:
Tonight I got busy for a few hours with some thin sheet metal to start the metal mock up:
First was the bottom half/tray that'll mount on the aluminum cross bar:
After bending a top, we end up with this version, minus the sides needed to finish it - to say this is rough is an understatement:
Crappy pics by iPhone.
If this progresses further, I'd like to finish the interior with some neoprene for padding and the exterior with textured paint. I may also opt to try either a local metal working shop to construct another version of the box, or maybe a local fiberglass company to build one that way - we'll see. Just having fun playing now.
