Making gourd shapes – or water tanks?

We have an order for public sculptures of 6 gourds brought by the first Maori to Gisborne.. Two are done and placed in the Captain cook memorial park, and now we are doing the last 4. The shape is suitable for water containers too…

The way I built the frames for these two was pretty quick- I drew the profile on recycled particle board, screwed screws along the profile for bending the vertical ribs to, measured the length, cut nine d10 (10mm deformed ie indented) rebars for the large gourd, 6 for the 900mm one, then bent them to the line of screws. I pre-bent the right angle bends at the base using a bender tool.

Then D10 horizontal ribs, circles (bent around a barrel and a concrete cone cast from a road cone) were tied to the vertical ribs on the inside. Then I wound fencing wire (medium tensile, heavier gauge ‘no.8’ wire) around the outside of the ribs. The ribs of the big gourd were supported by a drum shape bent from 150mm square mesh.

Carving the spiral

Just spent most of today doing this, in between visitors… overnight setting but still nice and soft to carve… in a twist of the unfolding it’s now not for the bronze ‘sunwheel’ – clients want a smaller one for that… will buy this one as well for a different site… with whatever feature I come up with… including carving…so I went for a celtic knot plus some branch hints and on one side a medallion probably to have a celtic knot in it too…

Note the tungsten scraper and also the steel ruler which scraped at an angle around the spiral helped true up the curve.. on a boat hull this is I believe called ‘fairing’ the lines. Also for carving the knotwork I found it helpful to paint primer on first so it is easier to draw and see to cut to the lines… More work needed but at least main carving done while plaster is softer. Tomorrow it will be harder. ..but still ok to scrape with tungsten blades.

Spiral herb garden progress

Well I’m finally back to ferrocement, in Gisborne now based at Dreamspace gallery and workshops, 61 Carnarvon St. Main focus in the ferro: ‘dreamhavens – cabins you only dreamed of’… see www.dreamhaven.nz  . (formerly hobbithaven – this was lost in cyberspace when my old email peter at eutopia disappeared with eutopia.co.nz – sigh!)

The Tairawhiti Environment Centre here asked me to make a herb spiral for them, and a garden path edging. Here are some photos. The spiral was a challenge as it is a complex shape to bend steel to – a spiral of steel rebar becomes a giant spring which needs strong framework to hold it. I put it over a ‘christmas tree’ frame specially made for forming circles and sprirals. But next time I will try welded joins – tied ones slip and the spiral twists… So, welding learning curve next… Also note the colour – hybrid of some ‘marigold’ oxide in the final coat and a wash of iron sulphate (used in lawn care for moss control) within a day of last coat and carving of it. Also note the black non-woven weedmatting for protection while the plaster cures – we got a 4 metre-wide roll of the thick felty stuff from Permathene which works well as it is wettable, doesn’t flap about, and won’t tear or fray like woven does. Raewyn will help fill the spiral and plant it. We are donating it to the cause – good advert I hope!

The garden edging took a lot of bending over and joining up 6 metre lengths, but it is very strong. They plan to fill it with smooth pebbles.

ferrocement birdbath fountain, carved

I did this (based on the cafe eutopia fountain we did 12 or so years ago now, still the centrpiece of the courtyard) the week we returned to Gisborne for the birth of our first grandchild (Bruno – he’s doing well, looking forward to seeing him play around the carved raised beds we made… As you can see, a few more sleeps before that can happen!).

Anna wasn’t sure about doing water in it so I just made it as a birdbath for now. The ‘finished’ photo isn’t quite – it rained overnight and the paint wasn’t quite dry enough to do the ‘shadowing’ effect by painting on black acrylic paint then wiping it off – you can see the parts where I did manage to do it before I had to catch the plane back home!

the whole thing took about 2-3 full days I guess. Carved mainly with the tungsten paint scraper I recommend in the book Fantastic Ferrocement. http://www.smashwords.com/books/view/152684

I did make a smaller tungsten chisel for the fine details that were in deep inside the ‘tree roots’ where the scaper couldnt reach. I will post on that later – when I’ve perfected it!

Five 6mm rods were the upright reinforcing, with roughly 2mm soft wire wrapped around it to make a finer armature for the two layers of chickenwire (more than two counting inevitable overlap on the curves). Instructions in Fantastic Ferrocement stand – some minor developments, such as using straight rebar tie wires instead of bag ties for tying the rebars together.

Note the whitish first coat – Resene Limelock to seal in the lime for painting before the plaster is cured. The twist going up the ‘trunk’ is all added – carved into the second thick coat of plaster. Also the ‘roots’ all carved from the extra thick plaster around the base.

I noticed again doing this how good it is to use plenty of plasticiser and mix in the concrete mixer longer than usual for the second coat, until the mix is aerated and wonderfully light and creamy to spread on. Also of course used plenty of fibre. These two things made it possible to get around a one inch  to two or three inch (25-75mm) layer near the base – in one coat.

A deep birdbath/fountain like this can be made safe/shallow for little children by putting gravel in it, I think.

It went so well, while my other stuff (more conceptual things like the Qor game, and my philosophical writing) has been falling on indifferent ears, that I’ve decided to take several people’s advice and do art for a change, sculpt and perhaps paint again, etc. And maybe make enough to keep bank, wife and kids happier…:) I did a little oak carving recently, in that spirit:

Moonwit Dreams, from my fantasy epic the Apples of Aeden. I made a silicone mould for it too, and have tried some casting in plaster of Paris, oil-finishing the casts by dipping in hot linseed oil, then finishing by ‘shadowing’ as in the original above with dark acrylic.
