I saw Fblades Funky-Retro-Cheap Ass Belt Buckle and thought that looks good but i wanted to make my own that i could put on different belts
Step 1: Tools
Here are the tools and materials i used, not all of them are pictured :
2 Flat screwdrivers to prise the cassette apart
Ruler and pencil to mark the holes to be drilled
Molegrips, snippers and pliers for cutting and bending the wire coat hanger
Drill with 3.5mm and 4mm drill bits
Wire coat hanger
Also not pictured super glue and clamps
Step 2: Dismantle the Cassette
Carefully open the case and then take all of the insides out, you can throw them away they are no longer needed
Step 3: Drilling the Holes
In this step you should measure the width of your belt so you can cut and bent the coat hanger to the right size, once you have measured the belt halve the amount you have and then you should have that amount on either side of the middle of the cassette then mark and drill(3.5mm). For the hole where the screw goes simply drill a hole(4mm) in the middle offset from where the tape used to be wound.
Adjust the size of the holes you drill for the screws you use and the thickness of the metal you use.
Step 4: Putting It Together
When you have drilled your holes you should bend your metal so it fits in the holes like in the picture, then slide it into the case and bend the legs so that it stays in place, then put your screw into the other hole. You mite want to put the case back together to see if it will close.
Step 5: Last Step
The last thing to do is superglue the case back together, clamp it and leave it to dry then when its dry wear it and be all the envy of your friends.
