As presented at AGI 2004…
Riveted Bead Caps
Supplies
Jeweler’s saw (or glass saw, for small diameter tubing)
Dapping Block and Punches
Steel Block
Torch, Charcoal Block and Heatproof Surface
Pickle
Hand Punch or drill
Transfer Punches
Pre-cut metal disks from Rio Grande (24 or 26 gauge)
Leather Mallet or Hammer
Jeweler’s Files
Buffing wheel and polish (White Diamond and Red Rouge)For an average bead, we use ½” disks. Use a transfer punch to mark the center of each disk. Use a hand punch or drill to make a hole in the center of each disk. The tubing should be a snug fit through the hole in the disk. Put the disk into the dapping block. Choose a punch that fits the hole in the dapping block and use a hammer to hit the punch a few times until the dome is a well-formed cap that fits nicely on your bead.
Place a cap on each end of the bead. Insert tubing through the bead and both caps. Mark and cut the tubing so that you end up with 2-3mm of the tubing sticking out of each cap. Don’t forget to allow for the length you’ll lose when you file the ends of the cut tubing! If you anneal and pickle your tubing before the riveting process, the ends will flare more easily.
Working on your steel block, begin with a dapping punch slightly larger than the inside dimensions of the tubing and use a hammer to gently start to flare the end of the tubing with a couple of taps. Turn the bead over and flare the opposite end. Return to the original end and repeat this sequence using increasingly larger punches.
After the rivet is flared to your liking, polish the caps. Take care not to heat the bead too much in this process; it can unanneal your bead and/or cause it to crack. Use Emery paper to remove any scratches, then polish.
Silver Core Beads
Supplies
7/16” OD Stainless Steel Tubing coated with bead release
11 mm diamond core drill bit and Dremel®
Jeweler’s Saw
½” diameter sterling silver tubing
Torch, Charcoal Block and Heatproof Surface
Pickle
Corrugated cardboard
Dapping Punches
Leather Mallet or Hammer
Steel Block
Jeweler’s files
Buffing and Polishing Supplies (White Diamond and Red Rouge)Make a bead on the stainless tubing. Experiment with various widths and thicknesses, but we’ve found that beads less than 9mm wide and 6mm thick tend to break during this process. Anneal. Use the core drill in water to open up the bead until the sterling tubing just fits through the hole.
Cut the tubing so that 2mm extends on each side of the bead. File the ends until they are smooth. Anneal and pickle the tubing.
Make a hole in the cardboard that is slightly larger than the diameter of the tubing. Place the cardboard on top of your steel block and place the tubing into the hole.
Choose a dapping punch that is slightly bigger than the diameter of the tubing. Use the leather mallet to tap the punch into the tubing 3 or 4 times or until the silver starts to flare. Turn over and repeat. Choose a punch that is 3 or 4 sizes larger and repeat until the tubing is nicely flared.
Turn the large punch over and use the flat side against the silver to finish hammering the silver down flush with the bead.
Use Emery paper to remove any scratches, then polish.
We first learned of these techniques through the articles listed below. We are indebted to Bronwen and Susan, and very grateful for their generosity! It still took a lot of trial and error, and lots of practice to end up with something we liked. We finally developed methods for creating these beads that suited us. We have formulated this demo for folks who, like us, have little or no metalsmithing experience.

For Riveted Caps —
Tubing for beads made on a 3/32” mandrel: 2 or 3mm OD
Tubing for beads made on a 1/8” mandrel: 3 or 4mm ODFor Silver Core Beads –
Some folks use sterling tubing that is the same size as their mandrel. I find that the bead release makes the bead hole a little sloppy for a good fit. Your mandrel should be slightly smaller than your tubing.[FONT=Trebuchet MS]Tink

Beth"In the South, the breeze blows softer...neighbors are friendlier, nosier, and more talkative. (By contrast with the Yankee, the Southerner never uses one word when ten or twenty will do)...This is a different place. Our way of thinking is different, as are our ways of seeing, laughing, singing, eating, meeting and parting. Nothing about us is quite the same as in the country to the north and west. What we carry in our memories is different too, and that may explain everything else." --Charles Kuralt in "Southerners: Portrait of a People"

(Jump Ringer Saw Blades for the Foredom Flex Shaft)September 9, 2004 at 5:49 pm #1067613When I started searching for some images of completed riveted and core beads, I realized how few of them I’ve actually photographed. The ones I make these days typically go to established customers who don’t need to see pics. (Oh how I love you guys! LOL!)
Here are two pics of my very first silver core bead (Teal Seeded Glass with enameled black trails) and one display pic of an etched riveted heart with some cool surface treatments.

I have the Harbor Freight punch and had trouble with it … I think because my sterling sheet was too light. What gauge are you having success with?
Thanks for this tutorial; I really appreciate your time & expertise!

Nolly, I’m using 24 gauge disks. I’d like to try something around 26 or 28 sometime to see how that works.
