Have you ever watched a metal craftsman in action
such as a Blacksmith at a country fair... most people watch in awe as
the Blacksmith carefully heats a piece of iron in a charcoal forge
before placing it on the anvil and then proceed to hammer it into all
kinds of unique shapes, it all looks pretty simple doesn't it...and the
Blacksmith would probably tell you that it's not that difficult to
hammer & shape things from red hot metal simply because it is quite
fluid.
He's right you know, generally all it takes to work with metal is
a small amount of knowledge & instruction, and some solid
practice, and before too long even a novice will be producing
good quality metal craft items.
But there is a lot more to metal craft than just blacksmith work.
While you can't deny that blacksmithing is a lot of fun, and a
skilful worker can make many practical and ornamental items.
With a little practice you could also produce beautiful iron
work, simply by using basic skills & equipment.
In the early days the blacksmith was one of the most sought
after "skilled" workers in the village.
But you know, you can take the art of blacksmithing another
step. You could use the forge to melt metals.
What
if you created a small charcoal fired furnace using your existing
forge, it wouldn't take much work to build up a simple circle of bricks
on the forge hearth to form a deep bed of charcoal so that you could
produce a bed of red-hot glowing coals which will produce a large
amount of heat. Enough to heat and melt aluminium... maybe even bronze.
Of
course a crucible is required to place the scrap metal or ingots in for
melting purposes,and the crucible needs to be buried in the bed of
coals so the heat of the charcoal will do its work for you.
All you need to do now is to apply a gentle blast of air from the
forge bellows to begin building the heat in the charcoal, and the
crucible with the scrap aluminium, or home made ingots will quickly melt in the crucible.
Most
hobby workers use a small electric motor attached to a blower to
produce the correct amount of air blast, but for the moment, the manual
operation of the forge bellows will suffice.
High quality
hardwood grade charcoal will produce a high amount of heat, in fact
you'll notice with the added heat the alloy ingots will soon start to
melt, and once that happens the pool of metal in the bottom of the
crucible rapidly promotes the total melt.
Once the metal has all
melted, it is ready to pour into a sand mould. The idea is to prepare
your sand moulds well before the metal has melted, so that everything
is set up and ready to go. Once the methods & techniques are
learnt, the whole process is quite easy and straight forward.
Any practical minded person could do it.
