Excuse the picture quality it was taken with an old 6mp samsung compact.
Step 1: What You'll Need
An old reflector: (this is kind of essential I don't know how I would have done this without it.) You must have the bracket as that will be the bit you're using. The reflector itself can be used another way (if riding fixed) as showed below
Two picture hanger things: I don't know what you call them and as you can see mine are different sizes but they can be bought from anywhere whether it be ASDA (Walmart) or B&Q.
Nuts and Bolts: Details in the picture (With the exception of '5x20mm' I don't know what any of that means.)
A spacer of sorts: In my case my handlebars were a tad narrow for the clamp which meant I needed to use one. (A bit of blue tack would do it.)
Screwdriver: Obviously the type depends on your bolts.
iPod/iPhone (or similar)
Advisory case: To avoid material damage to your device.
Ruler's just for show.
Step 2: So We Begin.
2. Bend out your 'picture hanger things' so that the curled bits of metal where the nails go through run as flat as possible (I used the swiss army knife's flat body to aid in this.)
3. Bend them to fit your device as shown.
Step 3: Nearly There.
2. Lay the bracket over the top of the bolts. The side of the stem you're mounting it will dictate which way you do it.
3. Screw on your bolts. If you find at this point after the bolts have been tightened that the device isn't held securely, do some re-bending of the 'picture hanger things.'
4. Place it over your bars using a spacer (if needed).
The end result should actually be very solid when mounted. If not re- consult the steps and try more re-bending.
