1. First, punch the belt surface from the front with a 3mm punch.
2. Put the long nail of the rivet on the base.
3. Nail the belt cover.
4. Install a short cover on the belt.
5. Align the rivet die with the short cap and beat the die with a hammer. It's best to get it in place at once, and make it stronger.
6. Finally, take a look at the installed front view.
