Meltdown-Oxycutting, William Wallbank and Sons, Auburn

The now derelict 'William Wallbank and Sons' was a foundry on the Parramatta Road, Auburn, built in 1932.
I've been painting the machinery before it is all stripped out and sent to a scrap metal yard.

Some of the ladles and other machinery that couldn't be sold intact were being broken up for scrap by oxycutting. 
During this exciting process, I painted some small and medium circular canvases, known as tondos.
In Art, the circular format of the tondo was often used for religious subjects.
Extreme chiaroscuro was also exploited by artists such as Caravaggio, to heighten the contrast between the gloomy background and the intensely illuminated saints or angels.
The fire in the dim interior gave the scene a mysterious atmosphere, reminding me of the nocturnal paintings of one of my favourite artists, Georges de la Tour.
Figures in his paintings are enveloped in shifting accretions of darkness - hands and features picked out by pooling, smoky light.

Oxycutting is one of the oldest welding processes.
A torch is used to heat the metal to its kindling temperature. When it's cherry red, a stream of oxygen is focused on the heated part and chemically reacts with the ferrous metal, producing more heat and forming molten iron oxide which is then blasted out of the cut.
The melting point of the iron oxide is about half that of the metal being cut, so it will immediately turn to liquid iron oxide and flow away from the cutting zone.

Starting a cut in the middle of a workpiece is known as piercing.
Once it has started, steel can be cut surprisingly quickly, far faster than if it were completely melted through.
Sometimes remnants of iron oxide remain on the workpiece, forming a hard "slag" which can be removed by tapping or grinding.

The hottest part of the flame is approximately 6,000 °F (3,300 °C) - hot enough to easily melt steel.
But the flame of the cutting torch is not intended to melt the metal, just bring it to its ignition temperature.
The rest of the heat is created by the burning metal itself.

.
A basic oxy-acetylene rig is faster than a petrol-driven cut-off grinder, as well as lighter, smaller, quieter and not as prone to severe vibration. 
Oxy-acetylene torches can easily cut through ferrous materials as thick as 200 mm. 
However oxy-acetylene has its limitations. It can only efficiently cut low- to medium-carbon steels and wrought iron.
High-carbon steels aren't suitable because the melting point of the slag is closer to the melting point of the parent meta.The slag from the cutting action mixes with the clean melt near the cut, which means the oxygen doesn't reach the clean metal to burn it. With cast iron, graphite between the grains interferes with the cutting action of the torch. Stainless steels can't be cut either with this process, because the material doesn't burn as easily.

Painting this was fascinating, but there was an undercurrent of sadness, as it
marked the point of no return.
The life of the former foundry was at an end, and its vivisection will be the last fires lit inside.

"Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice."

"Fire and Ice" by Robert Frost

Steady rest

I've been painting the machinery in the William Wallbank and Sons ex- foundry in Auburn, before it is all stripped out and sent to a scrap metal yard.

I've been painting a series of still life studies on salvaged "press plates".
These leftover circles of mild steel were found lying on the machine shop floor, and were being gathered up to be thrown away.

It was fascinating painting the relics of industry on salvaged objects that were part of the waste product from that industry.
The lustre of the smooth metallic surface shows through every brushstroke, reproducing every sparkle, shine and glimmer of the knobs and finials.

Although the William Wallbank foundry dated from 1932, some of the machinery was much older. I found a nameplate on one from "Russia", which meant that it must have dated from before the Soviet era, and probably from before World War I.

The steady rest on a lathe, has a frame and 3 adjustable jaws to support a workpiece such as an axle or a shaft while it is being turned, milled or drilled.
It prevents slender, flexible pieces springing back and forth, and also allows deep cuts, drilling, boring, or internal threading.

The over arm with the top jaw can be unfastened and swung out of the way so that pieces can be removed and replaced without needing to adjust the jaws.
There should be 0.001 inch clearance between the jaws and the workpiece.
The bearing surface is usually machined directly on the work.

When the work is too small or awkwardly shaped to machine the bearing surface, a 'cathead' can provide the bearing surface.
The cathead has a bearing that is surfaced, a hole through which the work extends, and adjusting screws to fasten the cathead to the work.

When it isn't possible to hold the work in the chuck, one end can be supported by the headstock centre and the other by the steady rest.
A leather strap or rawhide thong is used to tie the work to the driveplate and to prevent it from moving off the headstock centre.

After the locking screws on the adjustable jaws are tightened, the bearing surface needs lubrication with heavy oil before turning on the lathe.

The bearing surface and adjustable jaws always need a heavy oil film between them, as when the workpiece heats up it will expand, closing the distance between it and the jaws.
