If I Had a Hammer...

Now that I have that tune stuck in your head, let’s switch gears from 60’s folk music to swinging an actual hammer.  One of the most satisfying processes in creating jewelry is using a hammer to add texture and dimension to a piece. Taking out your frustrations on an innocent piece of metal can truly be gratifying. Many wire artists, however, shy away from wielding a hammer because it seems too intimidating. Many say, “What if I do it wrong?” or “what if I destroy my work?”.  Those are some valid fears. You can take all of the mystery and apprehension out of the equation by arming yourself with a lot of knowledge and a little guts.
Let’s first get up close and personal with the hammer. The hammer most often used in creating wire jewelry is a chasing hammer. When used in metal working this hammer is used with chasing tools to embed grooves or lines in metal. It’s also used in setting rivets, stamping, and other texturing processes. For the wire artist it’s used to flatten and texture wire. Looking at the tool you’ll notice that the head of the hammer has two sides, one that’s wide and somewhat flat, the other looks like a small knob. In brief, the wide flat side is used to shape and flatten wire. The small ball peen side is used to add golf ball-like texture to the surface of flattened wire. All chasing hammers look similar with a little variation in head size and weight. The weight of chasing hammers can range from 2 ½ to 6 ounces. Choosing a chasing hammer is a matter of personal preference. For the wire artists needs, a 3 or 4 ounce hammer will accomplish most jobs.


To successfully flatten and texture wire it requires resistance. To give the needed resistance the metal is placed on a thick piece of polished steel called a bench block. When the hammer strikes the metal the bench block causes firm resistance that allows the full power of the hammer to flatten the metal.  Without this resistance the power of the hammer blow would be ineffective. Bench blocks come in a variety of sizes from 2 ½ X 2 ½ inch square to 6 x 6 inch square. The bench block that you choose is entirely up to you.
 
Before we begin swinging a hammer it’s a good idea to go over a few points of safety.  It’s always a good idea to protect your eyes so be sure to put on safety glasses before hammering. It’s also important to avoid hitting your hand with the hammer. To properly flatten and texture a piece of wire, though, you’ll need to hold it securely in place. This puts your fingers at risk. So what can you do? It isn’t necessary to hammer the entire length of wire at the same time. Some of the wire can hang off the side of the bench block. This gives you something to hold as you hammer. When one section is complete, turn the wire around and hold the newly hammered section while finishing the process.
Keep Your Fingers Out of the Way

Now that we have a basic understanding of the hammer, bench block and safety rules we can have a look at using the hammer. We’ll begin with flattening wire. Place a 3 inch (7 cm) piece of scrap 18 gauge wire on your bench block – a larger gauge can be used. Using a chasing hammer, strike one end of the metal until it flattens (Picture 1).

Continue this action down the length of the wire (Picture 2). You’ll notice that the flattened piece of wire isn’t perfectly square. As you hammered, the metal was stretched in several directions causing odd lumps on the sides of the wire.

This is easy to fix. Set the wire on its side and tap it with your hammer to square it back up (Picture 3).

Now that the wire’s flat we can add some texture to it. Using the flattened wire, place it back on your bench block. Turn your chasing hammer around so the ball peen end is pointing towards your work surface. Now tap on the flattened wire in a random pattern with the ball peen head (Picture 4). It’s good to tap a little then review your work. Continue tapping the metal until you’re satisfied with the results.

Notice the pattern that it gives the wire. Those little divots will reflect the light in such a way that it gives the piece a sparkle.  

Finished
See that wasn’t as bad as you thought. Using a chasing hammer isn’t scary or mysterious if you understand a little about it. Adding texture in this way will not only add depth to your work, it’ll also give life to your creativity.
