Dances of Death
The Magic of Jean Tinguely
The material common to all of these projects is scrap steel [perhaps an interesting aside to conjecture as to whether an artist operating in today's credit-crashed global economy could afford to operate with such an expensive materil on this scale - a tangible illustration of the effect of capital on the form of art]. Tinguely manages to breath new life into dead elements of previous living machines through the creation of fresh machines and systems, creating crude but elegant devices such as the drawing machine below...

Tutorial 19/11/08
Sounded good to begin with, but after doing a half day of research, mindlessly downloading pictures of crashed or decaying aircraft and Jean Tinguely scultptures, the questions returned once more; if I am to assemble a series of sculptures then I still have to come up with some kind of rationale for their assembly; thinking of them as sculptures or designs makes little difference to my immediate situaion - by looking at death I may have been steered in the direction of a framework with which to create a thesis or narrative, but it is still a blanket concept.. the search continued for a methodology which which to name, construct, and set in motion the elements of a design at a more detailed scale..

The Cockpit: Pilot Instrumentation
Archaeological Windcatcher Clocks
Energy is provided by the wind, stored inside a variable speed coil mechanism, and redistributed using an escapment and control system containing a horizonal weight pendulum. This motion is transfered using wheels to a cylindrical weighted brush, which rythmically rubs away at the surface of the steel structural component still attached to the decaying timber...
This last image is a render manipulated with a simple radial blur in photoshop to represent motion. Overall I am happy with the image but the top left hand corner contain some slight pixelization that I may have to do something about...

Michel Gondry + Bjork
Another video, Hyperballad, does go beyond the singular celluloid surface, and collages various angles and images onto the frame. This reminded me of the Bryan Cantley drawing exercises the Masters students participated in recently; layering, distorted perspectives and coded surface textures are common to both artists... I guess it all leads back to the imperative of suggesting altered states within a static 2-d frame...
Theo Jansen's Strandbeest
Again, similar to the investigations into horology, this kind of influence may be more relevant when I begin to refine a design, this week has probably seen far too much thinking and reading, not enough doing!! But fascinating and inspiring nonetheless...
'Escapement'
The above self reversing process is an example of a mechanical process; the reilability of an escapement depends on the quality of workmanship and the level of maintenance given. A poorly constructed or poorly maintained escapement will cause problems. The escapement must accurately convert the oscillations of the pendulum or balance wheel into rotation of the clock or watch gear train, and it must deliver enough energy to the pendulum or balance wheel to maintain its oscillation.
[World's largest pendulum clock, Shinjuku]
The crucial element in escapement design is to give just enough energy to the pendulum in order to keep it swinging, and to interfere with the free swinging of the pendulum as little as is possible. As the lubrication of the escapement ages, friction will increase, and less power will be transferred to the timing device (for example, the pendulum). If the timing device is a pendulum, this means the pendulum will swing a shorter and shorter arc. Contrary to popular opinion, the time taken for a pendulum swing is not constant regardless of the size of the swing; the swing time changes with the size of the swing. Therefore, a dirty escapement will cause inaccuracy because the arc of the pendulum swing becomes shorter (the clock will speed up). To minimize this effect, pendulum swings are kept as small as possible.
For now I think all that is crucial for me to understand is the principle, a self-reversible, repetetive, oscilliatry process. The immediate obvious [metaphorical] link to my site can be found with the coming and going of the tide. I hope the fascinating details of calibration and tuning can be re-visited once a convincing design is up and running, but for now I guess I should leave the clocks alone for a while, and get some more drawings done.
I have been [quite rightly] advised to back up my hand drawings by scanning them; once this is done it should be simple to post them chronologically to chart the project.

Chrongraphs
The Greek words "chronos" and "graph" stand for "time" and "writing". A chronograph is a chronometric (time-measuring) device which contains a mechanism that allows to stop at least one hand to facilitate reading of the elapsed time.The chronograph was invented by a Frenchman, named Rieussec, back in 1821. Literally, this was the only timepiece that bore the name Chronograph rightly. It was actually written on the dial with a small pen attached to the index. The length of the arc of the circle displayed the time that had passed. The index was fixed, while the dial turned. In 1822, Rieussec was granted a patent for his invention.
The diagram above shows the typical gear train of a watch. The escapement of a watch begins with the escape wheel. Next you will have the pallet. The pallet makes contact with the balance wheel as shown in the diagram. The balance wheel swings back and forth and with each swing locks and unlocks the pallet as it engages the escape wheel. This arc-of-motion can range from 18,000 beats per hour to as much as 28,000 beats per hour on some wrist watches.
Seismo[graphics]
The small rod, f, which is seen at the extremity of F, is for the purpose of allowing electricity to be dispensed with, if need be. In this case the screw, h, is so regulated that F descends farther, and that f may depress the armature of the magnet just as the current would have done.
Apparatus for the Study of Vertical Movements.—In this apparatus, the contact is formed between a mercury cup, T, and a weight, D. The cup is capable of being raised and lowered by means of a screw, so that the two parts approach each other very closely without touching. At the moment of a vertical shock a contact occurs between the mercury and weight, and there results a current which, acting upon the electro, E, frees the pendulum of the clock as in the preceding apparatus. In this case, in order that the contact may be continuous and that the bell may be rung, the piece, A, upon falling, sets up a permanent contact with the part, a.
