Step 1: Gather the Parts!
- A 1.5" long 1/4-20 thumb screw (Not like the kind you break someone's thumbs with, but the kind that has a knob rather than a screwdriver slot)
- Some 1/4-20 nuts
- Some 1/4 -1" washers
- A 1/4-1.5" washer
- A 1/4-1.5" rubber washer
- A 1/4-20 cap nut
- A cheapo bike reflector
- A drill with a 1/4" drill bit
- 3 or 4 bucks
Step 2: Prep the Reflector and Thumb Screw
I then added three nuts to the thumb screw as a spacer. Could you use an actual nylon spacer tube? Probably. Would it work better? Probably. So why didn't I use one? I didn't have one, but I did have the nuts. You need this to keep the thumb screw knob from hitting the clamp screw.
Step 3: Assemble the Unit
So, some spacing things to consider:
1. When you tighten the reflector clamp on your handlebar the clamp screw may poke out through the top of the clamp. The smaller washers let it do this without hitting the big washer.
2. You don't want the camera to bottom out on the thumb screw, so add / remove small washers or spacer nuts to keep this from happening.
Step 4: Put It on Your Bike!
- The short screw and large / rubber washers increase stability.
- Using the second hole on the clamp means the camera screw doesn't have to hold the mount on your handlebar, which means that you can screw the thumb screw to the camera (easier than screwing the camera to your mount).
