A few days working at SculptCAD

I have been working with the Free Form program for a couple of days now, mostly focusing on making the duck that is part of the tutorial, but I have learned enough to generate this first 3 D model of my sculpture "Chicken Neck Johnson" for the SculptCAD Rapid Artists project. It still needs a lot of work before it is ready to be put through the 3 D printer.

At the End of the First Day of Construction on the Privet Sculpture Project

At the end of the first day of construction I learned that not all privet can be used the same. If the branch has any elbows it won't bend smoothly. The long shoots that grow straight up in one season are ideal for the ridged bundled arches that the PSP requires.

First Stake in the Ground for the Privet Sculpture Project

The structure will be staked to the ground using thick privet branches. It will be interesting to see what condition they are in after a year in the dirt. The dirt at this location is on about 10" deep then you hit lime stone, which is the reason this area is called Chalk Hill. The photo also shows some of the long privet branches that have been harvested to create the arched structure.

Location for the Privet Sculpture Project

The opening for Make Space: Installation at La Reunion TX is this Saturday, Feb. 27th. With all the rain and snow it has been hard for any of the artists to get out there, but I do have my sculpture sited now, and I have started the framing out of the structure. Above is the concept drawing superimposed at the site.

There has been some interesting issues around using privet as a building material, I'll blog about that later. Right now I need to get into my muddy boots and rain coat, pack up the truck and head out to La Reunion TX.

The Beam Plank & Flitch proposal for the Henderson Art Project

This is one of three Urban Timber Sculptures that Beam Plank And Flitch submitted to the Henderson Art Project. We focused on a minimalist approach that strikes a balance between the natural form and texture of the tree trunks and a graphic subtractive sculpture.

Privet, Basic Structure and Seed Distribution

The structure and seed zones of privet

Privet growing in the wild sends out branches from a central root ball. It has corresponding small branches that sprout along the main branch. As the main branch grows longer it bends, making an arch. The small branches on the top of the arch grow towards the sun light while the branches on the underside dry up and snap off, leaving rows of small stubs. These stubs are reinforced over the seasons to form a thorn like defense. This pattern of the branch arching, growing and branching out repeats every season resulting in the main branch becoming a series of arches that can extend over 10 feet in length (as observed at La Reunion TX).

With each season, new branches sprout from the root ball and grow straight up, using the older branches as support. Once they have cleared the leafy privet canapé, the small side branches begin. The seeds and new leaves will only form on new growth. The long clusters of hard round seeds tend to be located on the farthest tips of the branches where they can be seen by animals and whipped about in the wind.

Cutting a branch usually results in a growth spurt around the stump and along the branch. Cutting a branch at the base of the plant tends to multiple the amount of new branches sprouting up from the root ball.

New sprouting seeds

Cutting all the branches down to the base allows sun light to reach the unsprouted seeds, this combined with a little rain water will activate all the seeds.

Spreading the Seed

Frass, Droppings, Spore, Poop... What ever you call it, this is a big stinking pile of privet seeds.

One privet bush can produce thousands of seeds every year. These hard round black seeds have a multitude of ways of finding fertile ground. First is the structural nature of the bush itself. It grows in long arching branches that sprout from a central root ball. These branches drop seeds away from the root ball onto new open ground. The branches are also very wiry so in high winds they can act like whips to fling seeds further a field. Due to the small round shape of the seeds, they are easily washed into storm drains and creeks, this being probably the most common form of seeding in urban areas. Birds and some animals can eat the seeds, which are resistant to the acids in the digestive system, so they are excreted later in perfect condition to sprout in new locations.

Please note that privet seeds are slightly poisonous to humans, but they will kill a horse if eatten them.
