Place the TierraCast® link on the bracelet in desired location, and use a fine-point Sharpie® (or other extra black permanent marker) to mark where to punch the holes.
Turn the rotary leather hole punch to 2.5mm, and punch holes in marked spots.
Place the rivet post through the bottom of the bracelet, and set it on the steel block. Place the cap through the link, and push this onto the post. Place the rivet setter over the cap, and tap firmly with brass hammer. If it's still loose, then tap again until the rivet is set. See the Rivet Setter Illustration for details.
Add other rivets as decorative elements if desired.
Use BeadFix™ or 2-part epoxy to glue snap cap over top of plain snap.
If desired, curve the spiral link with bracelet bending pliers.
