Gwen Youngblood's Riveting Essentials Kit for Jewelry Makers and Artists The Wubbers Riveting Kit, developed by instructor Gwen Youngblood, will teach you to rivet like a pro. The hardest part of traditional riveting is measuring the wire prior to forming the rivet. With the three different Rivet Gauges (14, 16 and 18 gauge) included in this kit, measuring wire is easy. The Rivet Punches allow you to set rivets in difficult locations and also attach bezel cups. The Rivet Punches are 1/8", 3/16" and 1/4" to allow for a wide variety of uses. The tiny riveting block measures 1" and has twelve small divots ranging in sizes from 3 to 13.5mm. These tiny divots allow you to set round-headed rivets while maintaining the round head. A 28-page project guide with photos is also included with this kit.
