Drilled a piece of Montana, and made my wife, her mom, and our 2 daughters pendants tonight We had a great time letting everyone pick stones and bails, then I put it all together. I figured out a nice rig for drilling the pendant with no blow out, I will take a pc of it next time.

You've got some nice stuff going there, John! How was it drilling?

Could you share what metal you're using to form the jump ring, and do you solder it once it's in place? We just did our first drilled cab, and the method of making jump rings from round wire is not working. They don't stay closed. I tried a couple of commercial jump rings, same problem, with the added twist that of course the commercial jump rings I have around are not always going to be the size I want. Maybe they need a touch of solder. Tried it with silver and 14 kt. GF both...I don't know how to solder those materials but of course I can find out if that's what I need to do. Hubby has lots of experience in soldering the common metals used in electronics but not jewelry.
I should get off my duff and post the stone itself.

John, John, John. You are turning out to be a great cabber and jewelry maker. Giving the old timers a run for their money. It is also great that you are getting the rest of the family involved. In a couple of years you may have some competition within the family. Jim

Thanks all, Jim, I'd love it if the family got involved. My wife and mother-in-law said "you should sell your pendants." I replied, "well I want to just give them to everyone I know who would like one or more." My wife replied back "Yes, but after you've done that you're going to have tons left, and you should sell *those*" - got a chuckle out of that. peachfront, I don't know much about jump rings. I used 20ga 18ga copper wire with silver plating. I don't know if it will hold or not, but my father in law is pretty much the handiest guy I know and he said he had some solder that would work, so they were going to solder it at home. I *did* talk to a local jewelry maker about the rings and she said that to get them to stay shut a lot of jewelry makers DO solder, but that if you use heavier wire there was a way to get them to stay shut, as follows: - wrap the wire around a dowel or something cylindrical a handful of times.
- clip the rings out of the coil
- when you open and close them, don't stretch the ring open so the wires are in line with each other, they won't ever stay shut after that, instead open them by pulling them apart *perpindicular* to the line of the wire.
- when you close the ring, bend the wires back to center then rub the ends that touch back and forth several times so they rub against each other.
The key was not pulling the circle out of round according to her, instead pulling it open sort of like you pull a keyring open. I don't know if that makes sense, and I don't know if it will resolve the issue you are having. It seems the safest bet is to solder. I can't do that either though. I have looked into trying to meet up with a silver smith, she is interested in my stones possibly as trade for instruction in smithing. That feels a bit daunting to be honest, I am just figuring out how to tumble and cut rocks, so silver smithing seems like I may be wandering off a bit. Anyhow, still having lots of fun and learning as I go. *CATHY* - so here is how I drilled. I have a folding table with a hard top that I set a small, shallow plastic container on. I used a small bar clamp that had a rubber pad on the threaded part of the clamp, and I flipped it upside down so the metal end went under the table and the rubber, threaded end was above the table and the container. I pulled a thicker slab of some stuff I probably won't cab (call it scrap) inside the bottom of the bowl and then placed my slab of montana on top of that. I used the bar clamp to reach over the edge of the container and threaded it tight on top of the montana, so the montana, scap and container were sandwiched together, held tight to the table. I put enough water to just cover the top of the montana and used the dremel as instructed somewhere around here to first rough a spot and then switched bits to drill. I pulsed up and down for about 10 minutes and it cut through with no problems. Added bonus was that the handle of the bar clamp stuck straight up and I was able to use it as a guide as I went up and down with the dremel. I couldn't believe I didn't trash the montana, it actually worked pretty well.

Thanks, John. Reviewing the jump ring steps again, I have to conclude that the wire I'm using is too flimsy. Great summary of the needed steps here, I have bookmarked your post for future reference. I forgot where this thread was and posted our first drilled pendant in the cabochons forum...I'll just put one of the photos here at the bottom since it's a repeat across another forum.

Hi peachfront. I am the least qualified to speak on how to do this stuff so I hope someone more knowledgeable than me can weigh in on this.
The one thing I realized right away about drilling is that there is a relationship between how far from the edge of the stone you drill, which affects how big the diameter of the jump ring then has to be, which in turn dictates the gauge of the wire you use for the jump ring. There is also a material factor in there, if the wire you are using is soft, you probably want a larger gauge than you can get away with if the material is hard.
Having said all that I have no idea what the numbers in that equation are. Like most everything I do, for me it is "feeling it out."
I actually misspoke above when I said I used 20 gauge. I ORIGINALLY used 20 gauge, but it seemed too thin for the diameter of ring I needed given the distance of the hole from the edge of the stone. I redid it with 18 gauge and t was much more secure.
I hope that helps.

That is way cool about getting the family involved. My grandkids "help" me all the time. They have gotten a pretty good eye and give me great ideas. They like to pick out the things they want for jewelry, too. It's really fun, as I'm sure you know.
Sounds like your jumpring advice was very sound. At the risk of muddying the water.... You could make a big jumpring with 18g and form a "D" ring with it. I'm sure I can't describe it right (Sun. -my brain takes a holiday) but if you google how to make a D ring, I'm sure you could find something. The point is, not only will the back be flat, but the extra bends in the ring will harden it real well. You want something big and strong for those cabs.
