Step 2Fabrication
1) Cut plastic pipe to approximate length of flashlight.
2) Cut two slots crosswise in the pipe to constrain the bungee.
3) Cut pipe lengthwise so that a small gap remains when flashlight is inserted. This allows the bungee to squeeze both the pipe and the flashlight.
4) Insert flashlight into pipe.
Notes:
- You will slip with the knife. Don't put your skin in the blade's path.
- You may break a blade tip. Always wear safety glasses. (Don't ask.)
- No dimensions are critical.
- If your handlebars are not quite perpendicular to the direction of bike travel, you can cut the crosswise slots at a slight angle to make the light point forward.
