Copper toggles, almost done... (it's only taken a year!)

I have been working on this project for a year. No kidding - not a continuous year, but a year nonetheless, from the time I first got the notion to see if I could do this.

copper toggles, soldered and ready for enameling

 I have a passion for making my clasps look like an integral part of my work, rather than an add-on afterthought. Which is why I frequently stitch toggles for my beadwork:

It's not always a matchy-match thing, although I have a big case of the matchy-matchies (regardless of what they say on Project Runway ... sorry, Tim. I try to live by Tim's rules, but I will always be matchy-matchy!)

But I DO like for my clasps and connectors to look like they belong to my designs, so I end up making a lot of my own clasps.

For situations where beadwork toggles just don't seem appropriate, and copper and silver don't always work, I was often left scratching my head. So I started thinking ... I have hundreds of colors of enamels ... why can't I make some enameled clasps that will work?

I've seen enameled toggles and S-hooks out there, but the toggles and bars I'd seen didn't have soldered attachment rings; they had sawed or punched holes for attachments.

I dabble with soldering, and knew that the heat of the torch or kiln would melt my soldered joins: can't solder first, because the enameling process will melt the joins; can't enamel first, because, lordy! What a mess the enamel will make when you try to solder! I kept mulling the idea around, for months, and finally called my friend Barbara Lewis, who is known to dabble with enamels (LOL), and Barbara suggested I try soldering the attachments with Eutectic solder, which was created for enameling. She made no promises, but thought it would be worth trying.

Within a week I had ordered the Eutectic Solder from Thompson, but it was out of stock, and it was about 3 months before I actually received the solder. In the interim, I spent a couple of days getting out all my metalworking supplies, setting it all up, and then cutting and prepping the copper pieces which I would eventually solder, once I finally received my Eutectic solder.

Once I received the solder, I put it in a safe place until I would have time for the actual soldering ... I was wrapped up in a beadweaving frenzy! So, several more months passed ... and then, I was finally ready last week to try the Eutectic solder.

First problem: Remember how I had put the solder in a safe place? Y'all know what that means ... I had to spend 2 days looking for it! I finally found it, the second day, in the very first place I had looked - it was the safest place, and the place where it belonged, but my memory had told me I had left it in the package from Thompson, so I had been looking for a manila envelope, when actually, I had opened it, painstakingly labelled its Ziploc back "EUTECTIC SOLDER FOR ENAMELING" in giant Sharpie letters, and placed it with my other solders. If it had been a snake, it would have bitten me, but I wasn't looking for snakes ... I was looking for manila envelopes!

Fortunately, when I had prepped the copper pieces, I had made all the join surfaces nice and flush, and didn't have to spend hours sanding and filing to get a good flush connection.

I put away all my beadweaving stuff, then set up the torch, fire brick, and all the other tools and toys I needed for soldering, pulled out the Eutectic solder, which was in wire form, and proceeded to try to cut off a couple of tiny pieces of solder. Good grief! The Eutectic solder is impervious to cutting with my usual wire cutters! It is hard as a rock! I got stronger cutters, and managed to get a few pieces cut, although they were larger than I needed. But I didn't have a cutter strong enough that could cut the pieces smaller, so I was stuck with big pieces of Eutectic solder.

The instructions I had gotten verbally from Thompson when I placed the order (I had asked whether the Eutectic solder contained flux -- at the time I placed the order, I didn't know what form it came in) were to apply flux liberally, so I fluxed the heck out of everything. I let the flux dry, made sure my little copper wire attachments were lined up where I wanted them, placed the solder, and tried to fire up the torch. This is when I discovered I was running low on acetylene, but I finally got the torch lit, and the soldering went pretty quickly and smoothly. One of the rings moved a tiny bit, but I can live with it.

The Eutectic solder is silver, but that doesn't bother me, because I plan to enamel these babies. There's obviously way too much solder, but I don't know how I could have cut the Eutectic solder any smaller; again, the excess doesn't really worry me, because it should get covered by the enamel. *Hopefully*.  I smoothed the solder seams, then tumbled these pieces because they had been annealed by the flame when I soldered, but mainly to give them a good smoothing, since I won't be able to get rid of any lingering rough edges after I enamel them.

So, this is my progress after a year. Now these pieces have been put in a safe place (note to self: They are with your enameling mandrels), waiting until I have the time, energy, and inclination to haul out all my enameling stuff and get it set up.

Things would be so much better if I had a studio with dedicated space for everything, so I never had to deal with putting away one medium so I could set up another space- and tool-intensive one!

I'll let you know if I ever get these suckers enameled! Fingers crossed! Hoping the solder will hold!

Wavy Soldered Bangles

I ended this week by making these sterling silver and copper bangles:

soldered wavy bangles

My friend Deborah (we think we are twin daughters from different Mothers, because of the many similarities we keep discovering we share) is to blame for these; a few months ago, she mentioned the new bangle presses available from Wubbers, and next thing you know, I had purchased yet another toy!

I let the presses age for a few months, as one does, and then I decided to give them a whirl. My first project was a pair of "Ruffled Hoop" earrings that Wubbers has a free tutorial for on their website (registration is required, but is also free); these earrings were an unmitigated disaster: the wire gauge proved to be too small to withstand the pressure from the press. Multiple attempts were made. So I gave up on the earrings, and a couple of weeks later, had time to try the bangles.

The bangles are also from a free tutorial at Wubbersu.com. As with most of my soldering, the hardest part was trying to get the 2 edges of the join flush prior to soldering. But after several hours, I finally did. (Which is why I rarely solder - it just takes to long for me to get the 2 sides flush. Wish I knew why ... everyone in all the videos makes it look so easy. Aarrgggghhhhh!).

But anyway ... I did the copper ones first, not wanting to waste sterling in case I was as unsuccessful with the bangles as I was with the earrings!

large wave (top) and small wave (bottom) copper bangles

The top bangle was made with the large wave press, and the bottom one with the small wave press. I like the way they turned out, but all the effort I put into texturing the 2 bangles pre-pressing, just as described in the tutorial, was wasted, as the press smooshed all my hammering and texturing into what you see above. They look fine, but you can't see the beautiful textures I beat into each one!

Then I moved on to sterling, and I decided to try something different. After soldering the 2 bangles, I put them on my steel bracelet mandrel (separately), and hammered a beautiful texture into each one. (the tutorial called for hammering the wire flat/texturing it prior to soldering, which causes the flattening of the bangle to be oriented in a different plane than if you flatten the soldered bangle on the mandrel (trust me on this).

So, then I put the sterling bangles into the presses, one into the large wave press, and one into the small wave press.

When I started to hammer the small wave press, after about 3 or 4 good pounds, my bangle sproinged open at the join. Oops. I will have to doctor on that one later.

The bangle in the large wave press fared better, but interestingly, the press turned my hammered/flattened/textured surface 90 degrees perpendicular to the way it HAD been oriented, which I wasn't expecting. It's an interesting look, but, or course, the texturing only shows on one side.
So this idea has to go back to the drawing board, too, and I'm already mulling over some ideas on how to make this work the way I envision it.

But, in the course of soldering these bangles, I used up the last of the acetylene in my torch, so I can't make any more bangles until I get a new cylinder of acetylene!

Reviving a Mini-Zombie

Remember the Zombies? Those projects you're so excited to start, but then never finish?

I'm not doing very well on my resolutions to dig up some of my Zombies and finish them, but let's not dwell.

I AM doing better at not creating Zombies - much better. I used to start projects left and right, casting them aside a few days (or weeks) later for something newer and shinier. Now, I make a concerted effort to finish one project before starting a new one...but sometimes, stuff gets in the way. Know what I mean?

In the wake of the flurry of creative activities surrounding the 5x5 challenge I just finished, I almost created a new zombie!

Remember this piece?

Mojave turquoise pendant

I was just about to take it apart and redo it, when I was chosen for the 5x5 challenge - I set it aside on my workbench, in a safe place - and .... 2 weeks later (seems like 6 weeks!) - forgot about it!

It never made it to my box of Zombie projects in the Zombie cabinet, but trust me - I completely, totally forgot about this piece. Yesterday, I was itching for a new project, wandering around the bead shop looking for ideas and inspiration, and decided to wander back to the workbench for a stronger pair of glasses, and caught sight of this pendant.

I spent some time yesterday afternoon trying to extract the cabochon from its bezel:
 prying the bezel open like a sardine can - the stone is still stuck tightly in place!

finally: the cab is free!

Today, I'll get busy with this redo - starting with measuring and cutting the bezel wire. This was actually the hardest part last time, because of the irregular shape of the cab.

Stay tuned - I really will get this pendant finished. Soon. Fingers crossed.....

Mojave Turquoise Pendant

I have decided to take a break from beadweaving for awhile, and get back to working with metal!

I started this pendant on Sunday, and it is almost finished (it needs the final ultrafine buff, to really bring out the shine in the silver):

Contemporary Sterling Silver pendant with Mojave turquoise and CZs

The Mojave turquoise cab is just gorgeous - nice pinks and purples, and beautiful veining. It would make a gorgeous piece all by itself, but then I put it next to these 8mm lilac CZs, and - wow!  I really love this combination!

I started playing with designs on paper, and what you see in the 1st pic above is very close to my final drawing.

Freeform cabs are a little harder to work with; here is the soldered bezel:
Fine silver bezel

Getting the bezel the perfect length was quite a challenge, given the irregular shape of the cab!

The irregularly shaped bezel really didn't want to lie flat on the sterling silver table, and needed a little (a lot) of encouragement from the t-pins. Notice all my solder paillons,  lined up and ready for the torch!

Despite my best efforts, the t-pins changed the bezel shape a tiny bit during all this maneuvering, but once soldered, I was still able to get a good fit with the cab.

Next, I added the wire support for the CZs - I used 18 gauge wire for this (a decision I now regret)

18g wire soldered to bezel

The next step was to add the pronged settings for the CZs - I soldered these to each end of the 18g wire.

I forgot to take a pic of the finished piece before I set the stones - sorry!

Here is the back of the completed pendant, showing the bail:

Here is the front of the pendant again:

Pendant front - Mojave turquoise and CZs

I am not thrilled with the outcome - I love my design, but there are a couple of flaws in the execution. For one, I should have used a thicker wire for the CZs - when these are bumped, the wire moves and bends. Not really what I was going for!

The second thing I don't like is visible at the top of the cabochon - where you can actually see the wire along the bezel. Notice how it isn't visible at the bottom beside the bezel. This has happened because the cabochon narrows to such a sharp point there at the top, and when I was setting the stone, I had to push the bezel more there at the top to get a good snug fit, and when I pushed the left top side of the bezel over as far as I needed to, it revealed this wire. If I had foreseen this, I would have figured out a different way of soldering the wire to the bezel. Live and learn, right?

As I said, this piece still needs a final polish (and tumble) - if the wire hardens more, I may decide to live with the design. If the wire doesn't harden more, and keeps bending, OR if I just can't accept the way the piece looks at the top of the bezel, I will probably take it apart and redo it.

What do you guys think? I'd love some feedback!
