Metalsmith: Kitchen Tools in the Studio

Metalsmith
(A typically occasional series by Christine Cox)

The sweeps drawer under my bench used to be a mess. I had tools mixed in with metal scrap, used sandpaper, leather pieces, broken saw blades, and lots and lots of metal shavings from sawing and filing. It was a major undertaking to clean it and a job I avoided. At a local store I found a metal mesh drawer organizer. Now my tools all have individual homes and all I do to clean up the drawer is to lift the organizer out, dump out the sweeps and put the organizer back in. The mesh organizer is a great holder for my most-used tools too.

Silverware holders are also wonderful for organizing tools in drawers. Mandrels, sanding sticks and other hand tools will stay in their assigned slots without beating up their neighbors.

Metalsmith: Triangles and Squares

Metalsmith: Triangles and Squares
(another installment in a typically occasional series by Christine Cox)

templateA fast way to accurately mark 3 or 4 corners on a piece of work is to use a drafter’s template. For example, let’s say you want to put 3 tiny feet on the bottom of a round box. It can be difficult to line up 3 points that look good. Simply lay a triangle template over the bottom of the box and then find the triangle that is closest in size to where you want the feet. Mark the 3 corners with a Sharpie marker and you’re done. If you want the feet in a perfect square instead, simply use whichever square template is the correct size.

Metalsmith: Twist to De-Bur

Metalsmith: Twist to De-Bur
(another installment in a typically occasional series by Christine Cox)removebur-done

After drilling in metal there is often a large bur around the hole. It’s unsightly, dangerous and can throw off how your piece goes together. Eliminate it easily by using a drill bit that’s larger (by far) than the hole you’ve drilled. Chuck the large bit up into a pin vise. Place the metal, bur side up, onto a surface that allows the tip of the drill bit to drop down through the hole. I usually just place the hole over the V in my bench pin, or slide it off the edge of the bench, whichever is easiest. Press down firmly and twist to remove the bur. Caution, don’t go all the way through or you’ll be left with a hole much larger than you intended. Lightly twist back and forth a couple of additional times to clear the swarf and you’re done.

This is also a quick and dirty way to create a countersunk hole. Just push down a little harder as you twist to get the characteristic flared out edge around the hole.

4th Century: Coptic Alphabet

Books, Miniatures, Writing and Supports
(Timeline Project)

Coptic Alphabet
4th to 9th centuries – The Coptic alphabet was used in Egypt and was perpetuated thereafter by the Coptic Christian church. It was the first Egyptian writing system to indicate vowels.

Cross Pollination: Metalsmithing and Enameling

Image

Being both a metalsmith and an enamelist means that I’m constantly using tools made for one medium while playing in the other. I’ve made some fascinating discoveries that have made both jobs easier.

  • Better detail in Keum-boo (photo above)
    Keum-boo is the Korean art of fusing gold leaf to depleted sterling silver. The complicated technique involves heat and burnishing. Dissatisfaction with the level of detail I was able to obtain with traditional burnishing tools led me to a fiberglass brush used in enamel work. (Available from Thompson Enamel). Since the fiberglass can take the heat, it’s the perfect tool to pounce the leaf down into the smallest textural details while the metal is still on the hotplate. The photo above shows a piece of keum-boo over a texture made by passing the sterling silver through a rolling mill with a skeleton leaf. Just look at that awesome detail!
  • Glue that can take the heat
    If you are soldering something and you have difficulty getting the solder to stay where you put it, try this trick. Get some Klyr-Fire from your favorite enamel supplier. It’s a low-tack adhesive liquid which is made to take the heat of a kiln for just a little while.
    Using tweezers, dip each piece of solder into the adhesive before setting it into place on your piece. While soldering, the Klyr-Fire will last just long enough to keep the solder in place while you bring everything up to temperature. This is great for beginners who might burn their fingers while trying to heat flux to the glossy point and then add solder, or for those who tend to upset the soldering set-up while placing balls or chips of solder on a precarious surface. If you’ve been using hide glue for this type of thing, you’ll appreciate the lack of odor in the Klyr-Fire. (And in case you were going to ask, it won’t work for granulation)
  • Saturated pickle
    Sometimes a metalsmith needs pickle that’s really saturated to electroplate the silver line left on copper after soldering with silver solder. Save the pickle from enameling on copper. I keep a truly nasty pot of saturated pickle around for use in both enameling (to remove oxides) and for electroplating.
  • Polishing papers
    After years of experimenting, I have yet to find anything better than our 400 grit polishing papers for cleaning metal prior to enameling. Simply sand the metal under running water and with a few strokes the water will sheet off and not bead up. Perfect!
Triangle kiln support

Triangle kiln support

  • Triangle kiln supports
    You know how it is; every soldering operation is a new adventure in supports, clips, third-hands and binding wire. I’ve found that for flat items, which need to be heated from below as well as above, there’s often nothing better than a triangle kiln support (also available from Thompson Enamel). They’re made of steel, so they can take the heat, and they stay out of the way while you move the torch. They’re small and therefore not a giant heat-sink, as a soldering tripod would be. They’re far more stable than a nest or coil of metal. Use them right-side-up or upside-down for the best support option for the job.

    • The triangle kiln supports are listed in the Thompson catalog as “three point trivets” and are numbers TPT-1 through TPT-5
  • Old soldering tripod use
    If you have an old soldering tripod, use the steel mesh that came with it for transporting enameled items in and out of the kiln. Just bend the corners down so that you can get a kiln fork underneath. A piece of mica on top of the mesh will stabilize the piece during the trip to the kiln.
  • Silver Dust in the Sky
    If you work in either sterling or fine silver, save your silver dust when you are sawing. When you are enameling, use a sifter to clean out the silver dust and then sift a tiny bit of the silver onto your last fired layer of enamel. Fire it one more time and remove it from the kiln when the silver and glass have just fused together (think: fire polish). A quick polish and the silver will look like stars. This looks especially gorgeous on a dark enamel. You can also use the silver dust under transparent enamel (as you would silver leaf), but spend more time cleaning the silver ahead of time. You don’t want to pollute your enamel.

World’s Oldest Torah is in Beautiful Condition

oldest-torah_67952_600x450

There is definitely something to be said for making a mistake! In 1889 an Italian librarian looked at the writing on a parchment Torah scroll (the 5 Books of Moses) and decided that it was probably an inferior 17th century copy. He felt that the copyist must have been clumsy and that the letters were uncommon and strange.

Fast forward to the present time (and technology) and we find that the scroll was written between 1155 and 1225! The “uncommon and strange” letters were based on the Babylonian tradition of writing Hebrew rather than the Palestinian style with which our librarian was familiar. The benefit? The scroll is in perfect condition because it was mis-catalogued, and the world has the oldest existing complete Torah.
