Installation preparation

©2017 Barry Smith - Drill shaving on wood
Next week I hope to install the five post Water and Snake motifs post sculpture. Today I stated the process of finalising the work on the functional aspects of the posts including:

  • attaching the snake motif tops to help reduce cracking and keep water from rotting the tops of the posts; 
  • creating more reinforcing purchase on the legs for concreting them into the ground; and 
  • filling cracks in the timber and giving them a final sand and oil.

Preparing and attaching the etched snake motif top plates.

In a way there is not a lot to show but it basically took all day. As you can see from the photo above I finished as the sun began to set. Fiona's making red curry - probably be accompanied by a white???

Colour in a bleakish week

The past week has had its challenges including a visit to the hospital and finishing the re-skinning of the inside of the trunk of the Buttress Root sculpture at Little Yabba Creek.

But amidst that there was time to celebrate orchid colour and shapes.

This morning was cold and windy; but again nature offered spots of colour on the verges.

Sometimes persistence pays

I have been trying to find scraps of time to get a couple of projects finished: A School of Funky Fish 2  for an up coming art festival; and the Snake and Water 5 post sculpture.

After final grinding and polishing Funky Fish 2 is ready for packing and sending out west. Fiona provided valuable design advice on layout of the fish forms to create a sense of cohesion and movement. The timber base is salvaged camphor laurel - sanded and oiled.

I had finished the etching of the snake and water motifs but needed to remove all the shellac and paint to reveal the finished plates. That took a lot of methylated spirits and muscle. But I think the end results show the effort was worth it.

The final job on the Snake and Water sculpture, before installation, is to attach 4 etched plates to each of the 5 posts. Still a way to go but edging closer. I hope to do the install in the next couple of weeks.

Adding a new skin

©2017 Barry Smith - Welding in progress - photographed using the iPhone whilst having my eyes protected by a very dark welding mask - couldn't really see the image at all.
Almost two months ago I posted that I had all but completed the installation of the Buttress Root sculpture. There was remedial earthworks and signage to do. But then it was discovered that two spelling mistakes had been made in the routing process in one of the poems inside the trunk section of the sculpture as you can see from the photo below.

©2017 Barry Smith  - Spelling errors
What to do about that? It was decided that it would have to be rectified by creating a new skin that was routed with the corrected spelling; and install that over the offending text. Any other option would have looked bad. Over the last two days I have worked with Edith-Ann and Oliver (the welder) to install a new skin to the inner side of the trunk.

That sounds simply - but let me tell you that it was extremely difficult to get the skin to sit within the old trunk section. Many clamps and much gently brute force were required to get the skin to conform and enable Oliver to tack and weld it into place.

Still we got there after: clamping; tacking; welding; cutting off the excess when the the full weld was completed; grinding; buffing and polishing; and filling in the groove in the base with a hi-tech industrial concrete repair material.

A beautiful finished product - you would not know we have added a 4mm skin. The trunk in fact looks even more solid now that the trunk metal is 14mm thick. It all just needs to weather again.

The rectification was given sign-off by the authorities. I'm now officially happy; but tired after a couple of heavy days. We will raise a glass of red to the completion of the work.

A mammoth etching episode

©2017 Fiona Dempster - Deep etch
Fiona and I had set aside this morning to etch the 22 plates I have drawn up and blocked out for the five post snake and water motif sculpture I have been commissioned to do. Good news is that we got to do the job.

We dissolved  1kg of copper sulphate and 1kg of salt in 10 litres of hot water - lovely colours. Even though this etching process is sometimes referred to as non-toxic it needs to be done outdoors with all the necessary safety gear as it does give off fumes and it can burn the skin and eyes.

We began by leaving the plates in the etching bath for 5 minutes; but the mixture loses its potency as it goes along; so the last batch ended up being in the bath for just on 10 minutes. In the earlier stages there is also a lot of heat - this diminishes as the etch goes on.

To improve the etch Fiona was removing the floating copper residue off the surface as we progressed.

The plates look pretty messy when taken out of the bath; and need to be cleaned with a strong pressure of water as soon as they are out. If you don't wash the plates off the residue just fouls up the surface of the plates and makes for harder cleaning later.

We ended up with a great line up of etched plates - washed and dried and put out for the final drying before cleaning the paint and shellac block-out off.

We aimed for a deep etch and achieved this as you can see from the detail photo at the beginning and below.

Below is a photo of some of the copper residue that was left in the bottom of the etching bath.

Next step is to clean the shellac off with methylated spirits and the paint off with petrol. That is for another post once the job is done.
