Materials

A modern blacksmith generally works with mild steel, which is almost the same as wrought iron except for the small difference [0.1%] in the amount of carbon. Using the techniques and the heat from the fire the iron becomes malleable and the blacksmith becomes free to do what he likes and, more importantly, what the client likes.

Legs for a table. The material has been shaped and bent to look as though the metal has been held into shape by the balls and rivets.

I can work with wrought iron and cast iron for restoration projects, if they are requested by the client. Other materials can also be incorporated into a design to add colour, texture, contrast, reflect light/images or to help the function of the piece. Other materials include coloured and plain glass, wood, stone, mozaic tiling, copper, stainless steel and bronze.

Techniques

Blacksmiths, mainly over the past 3000 years, have invented various techniques to work the material in different ways. The techniques are performed when the material is hot and malleable and include forging [spreading, drawing down and upsetting], splitting, punching, twisting, bending, dishing, fire welding, heat treating [normalising, annealing, case hardening, hardening and tempering] and joining [rivets, collars and mortise and tenon joints]. All these techniques can be used individually or combined together to create a rich and infinite variety of functional and decorative items.

 

Techniques used while making a peacock head from 12mm square mild steel

 

Upsetting - squashing down the bar to add more material for the feathers

 

Spreading - moving the material [that has been upset] to the sides with the cross pein

 

Marking patterns with the chisel and O punch

 

Bending the bar in preperation for fire welding the beak

 

Fire welding the fold together by heating the bar up to melting point and tapping it together so it joins into one piece - amazing metal!

Bending the head round over the edge of the anvil and using the hardie wrench/pegs

 

Cutting on my curved cut off hardie tool

 

Spreading and shaping the end once it has been cut off

 

Punching the holes in by hitting an impession on one side then turning it over to pop a hole through

 

Other techniques

 


Twisting flat bar. Simlpy turn with the wrench and the corners or groves create the pattern

 

Twisting square bar

 

Drawing down - a forging technique [along with spreading and upsetting] where I am changing the section of the metal between the hammer and anvil

 

Splitting the metal with a chisel

 

Drawing down/Forging the split into a point/taper then bending over the bic

 

Dishing the copper on the swage block. The swage block is handy for dishing as I can use all the hollow areas to hit the sheet down into. It also accepts my tin smithing tools so I can planish it [hit the bumps down and smooth it off]
