Hammers used in Blacksmithing
Tuesday, January 13th, 2009At some point in their lives everyone has used a hammer. Its a hammer that you would use to change the shape of the metal otherwise its some other tool that was used to hit the metal in order to change its shape as that does not happen on its own. In its most basic form, that is what a Blacksmiths does with this hammer.
Hammering a piece of hard cold metal into a new shape is time consuming, requires a lot of effort and may not be successful. Its good to remember that when you apply pressure or force to metals they can be brittle depending on the particular metal so you can cause breakage and cracks. Its for this reason and this reason alone that you find blacksmiths pick and choose the material that they work with because it must be malleable in order to withstain the forming process. And before he tries to hammer it into shape, he heats it up until it reaches a consistency that allow him to hammer it into shape the shape he wants without damaging the metal.
Once the metal is heated in the forge, it is placed on an anvil and the Blacksmiths uses a variety of different hammers to shape the metal as he wants. In general the largest hammers, with the biggest and heaviest heads are used to create the basic shape and then smaller and lighter hammers are used to create the finer shapes and finishes. The blacksmith’s hammer is his main working tool in shaping metal and he has be strong to apply the force to the hammer blow, accurate in hitting the exact spot, knowledgeable about which hammer to use when and also be able to work fast – from the time the metal leaves the forge it starts cooling off and within a short time it will have cooled to the extent that shaping it properly become impossible.
There are many different application of the Blacksmiths hammer in metal working.
· Firstly is the one everyone knows – hammering the hot iron on various parts of the metal with differing amounts of force and from different angles to form a shape. This can include bending it to from a curve or create a corner of a specific shape. The hammer is also used hammer on the flat sheet of iron to make it thinner and create more surface area. This is known as “drawing†the metal. The reverse of this is “upsetting†where the blacksmith hammers on the sides of the iron piece to make is shorter and thicker.
· The hammer is used along with a “punch†to literally punch holes in the metal. The punch is placed over the spot where the hole is to be made and then hit with the hammer to create the hole.
· The hammer is used along with a chisel to either cut or split the iron. If you are wanting to cut through the metal, then you will use one end to hold down the surface of the metal and then hit the hammer on the other end which will then cut through the metal. The chisel can also be used against the end of the iron piece to split it into a Y shape.
* There is another use for a hammer that comes in handy when you want to make rivets or when you want to join two pieces of metal together.
· And finally, when if two pieces of metal are heated to almost the melting point and then the then hammered so that they meld into one piece; that is called hammer welding.
