Separate elements: The object is made up of 3 separate parts: the threaded turn piece (figure 1), the shaft (figure 2), the body (figure 3). Material: The object is made up of 2 main materials. That of a unknown wood and a small metal nail which has the ability to rust. The rust itself shows that the object has aged. Engraving: Object has a "British Made" engraved on the body. Durability: Does not break when dropped reasonable heights Manufacturing: Hollow in turn piece is evidence of that part being made with a lathe.

It has pivotal movement around the pin in the shaft. (Figure 4) The body moves laterally along the shaft. (figure 5) The threaded turn piece turns into the body to lock the shaft in place. Similarly the body and shaft can rotate long the threaded turn piece. (Figure 6 & 7) The body can rock along a the curved surface on the bottom of the body. (figure 8) The body can be placed flat on surfaces vertically and horizontally. (figure 9 & 10)

Threaded turn piece has curved element that fits thumb and finger comfortably. (figure 11 & 14) Shaft is not comfortable for you hand to hold Metal pin does not seem to be where you hold the object. Body shape makes it hard to hold and reference what is top and bottom.

----------------------------------------------------- Textural Observation
Wood texture leads us to identify the wood as possibly The patches of stains suggest an environment with sticky substances or materials.

Uninformed use speculation Possible use for this tool could be: Clamping of material between metal pin and body. Which can be locked by turn piece. Although the lack of length of the metal pin suggests this is not a good use fro the object. (figure 20) Reference measurement. Moving the body and then locking it in place allows the user to keep a reference measurement. (figure 21) Curve marking: Using the metal pin as a pivot point the user can rest a pen on flat of body and turn. (figure 22)

 After the initial observation it known to be scribe and more specifically in this case a marking gauge for wood and metal working. Also known as a scratch gauge. Parts: Stock, Stem, Pin and Turnscrew What does it do: It gauges not measures. Transfers a measurement from reference material and scribes (leaves a mark) that same size. Uses the edge of the material to create a parallell line. Who is it for: Its primarily for woodworkers but metal workers too. Why use a marking gauge over a pencil: Accuracy: The knife or pin makes a much more accurate line. Tear out: The pre-engraved line helps reduce tear out when doing the final cut. Tool Guide: If you have lines engraved by a scribe tools such as chisels have a good place to sit, less guess work. (the wood whisperer) Historically: Evidence of marking gauges for sale in the 19th centuries but more evidence of the pin's being for sale alone. this tells us that this was a tool many woodworkers were manufacturing themselves. (Mystery of the Marking Gauge, Popular woodworking Magazine, 2006, Jansa, 36) When know that the marking gauge in question was manufactured do to the "BRITISH MADE" etching. Historically made out of beech wood.( Types & Other Variations: While there is evidence of many types of gauge fabricated for specific needs there are a few more common ones. (IBID, 37) The Tenon gauge - used primarily for motis & tenon Panel Gauge - is a larger version used to mark out longer cuts and have a larger surface for bearing the right angle. Cutting Gauge - A form that replaces the pin with a cutting blade in knife or circular form. Two pin version - This allowed the worker to scribe two lines at once and improved productivity.
 Definition "A marking gauge, also known as a scratch gauge, is used in woodworking and metalworking to mark out lines for cutting or other operations. The purpose of the gauge is to scribe a line parallel to a reference edge or surface. The gauge consists of a beam, a headstock, and a scribing or marking implement, typically a pin, knife, pen or wheel. The headstock slides along the beam, and is locked in place by various means: a locking screw, cam lever, or a wedge" (Museums Victoria)  Context
 Then VS Now
Newer gauges are more commonly made of metal or a combination of metal and wood. Common improvements are rules added onto the stem and many contemporary ones use a circular blade.
----------------------------------------------------- Societal Impact Socio-Cultural Impact This tool and those like it helped created more accurate builds. Leading to more detail work and building. It has also shown to increase speed and productivity. It removes some elements of human error in the measurement process by using reference measurement to the material needed. Political Impact Even though there was some manufacturing of marking gauges historically they were made by the woodworkers and the parts needed could be purchased separated. Technological Impact With material and technological availability and progress happening the design has changed to use blades and have more circular designs. It is visible on the online woodworking communities that there is a resurgence in the more traditional designs using pin's and beechwood that has been facilitated by online DIY and education culture. ----------------------------------------------------- Augmentation
Issues Grip and agronomics could be improved for ease of use. Stem gets stuck and doesn't slide through stock easily Stock rock's not clear by there is a curve Solutions Make attachable rubber grip for pin to apply pressure at scribe. Elongate the stock and put ribbing for the comfort of the hand Include laser engraved ruler on stem Include metal shaft for the stem so it slides more smoothly Flatten the bottom of the stock so that it doesn't rock when set down and can be manufactured more quickly.

In addition to the physical abstractions there are concepts regarding: Reference | Measurement | Craft which can be abstracted from this object.
1937 - Karel Honzik - Biotechnics: Function Design and The Vegetable World
Form as a ecological process Internal forces and external forces interact to produce form so form and function are continuously interacting. Meaning that if performance requirements could change then form and function are both dynamic in nature. Technology is a natural process because natural and manufactured forms are driven by the same fundamental objectives of efficiency and suitability. Man and Plant reach the same outcomes even from different outcomes, plants arrive at it b its own tropism while man uses intuition, experience and calculation. Although we both strive for intrinsic perfection of a final form both the natural technology and man made technology can only be invalidated by the emergence of new conditions. Finite Solutions deny inevitable progress, highlighting need for adaptability. While some examples of exceptional biotechnics (Victoria regis & bamboo) The multiplicity in nature should lead us to doubt finite solutions. Nature does not have finite solutions (look at diatomacae with its 6000+ forms) so why should mans inventions. Uses the example of a chair, While in any given moment one may have the “perfect form” but what happens if humanity started sitting in a different position. The form would have to adapt to that new position.
Tropism: the turning of all or part of an organism in a particular direction in response to an external stimulus. Overall Take away from this was the general push towards designing something more adaptable. The design needs to adjust according to changing needs.
Architectural Fragment Sketches
Adaptable rise with changing needs as one gets older Adaptable/changeable in style and material Replaceable when broken or deteriorating Has movement along a shaft with a locking mechanism Has lateral movement Adaptable to changing needs and programing Permeable/ paving that ages with use and tells the story of the space.
Discussion Notes | Thoughts | Sketches | Further Research Look at less literal elements of the object, revisit grander ideas such as measurement, reference. Look into how he human gate changes over time. Feedback suggested that the slower adaptability was interesting but specifics of the human body needed to be referenced.
Stairs | Comfort | Dimensions The higher the use the more comfortable the stride needs to be. Low use means you can sacrifice the space and make a less comfortable stair rise and run. Rise + run rule of thumb for comfort: rise + run + 18" Less than 10" run leads to many injuries and even deaths in Canada and has pushed for a change in code. The run should increase depending on foot size. For kids could/should be smaller. Optimal rise run in US/Canada 7-11 Optimal rise for seniors is between 5.98" to 7.48"
1960 - William Katavolos Organics In this Katavolos talks of the intersecting fields of the built environment and chemistry. He takes a much more scientific approach to design looking into systems that exist in nature to help influence how we develop elements of the build environment. 2002 - SLA Changing Speeds
In this exert SLA talks of a series of system based layers that make up buildings. Each layer of the system has a life-span. If These layers are two tied then the building becomes too rigid. Where if the structure is tied to the facade then the lifespan of a structure becomes much shorter based on the lifespan of the facade. They propose more flexible designs that function on a more systematic level. The major take away from these two articles for me being the focus on systems in design. How can looking at the built environment through systems influence the design.
Half a House | Incremental Architecture
Half a House is a interesting approach to affordable housing in Chile. Consists of homes that are build to be able to expand affordable twice their size. The owners are initially paying for what they need with the ability to expand when their needs change or it is economically feasible for them. Also gives a sense of owner ship over the homes as they get expanded to fit the specific needs of any given user.

Design Developments
These development sketches detail a potential shift towards a more systematic design influenced by SLA & Katavolos. Which can change over time. A structure which becomes more incremental and adaptable over time in more ways than simply changing the rise/run of the stairs. Potentially adding shelving, landings, half steps for children or adjustable handrails for varying needs, reducing the need to replace things all together. Conversations with the class concluding these developments were a push towards revising the origional object and bring that into consideration again and really outlining whats crucial and important to the objects.
When development of a model began i reached a time where i had to start looking at the realistic scale for the structure. I didn't really like the needed density and how much space it actually occupied. As a concept it works in section but not so well in 3D. This led me to take the flexibility I like from this idea and revisit the object and other concepts to develop something that works more closely to the object.
In revisiting the scribe itself and some of the major concepts. I mapped out the over arching themes i wanted to take from the readings as well as the core themes and concepts of the scribe. The scribes relationship to how it interacts with the body, craft, construction and the inspiring way it moves and locks made me redirect my focus back down towards a smaller scale. I still focused on adaptability and flexibility but rather than focus it around changing over time for the individual I thought about how a programs should be more flexible an adaptable. I starting thinking about how objects can influence and create systems my being able to shift and adapt to the changing needs of multiple users.
Farm Table Design
Shift back towards looking a the object led to the exploration of a more adaptable design that is used and adapted more frequently to both the body and programing. The craft associated with the use of woodworking scribes is closer related to this design through the materiality of it and how it would be built. A adaptable table designed to allow a more diverse use. Adapting to users in different ways depending on their needs or as their needs change as suggested by Karel Honzik. It consists of three variable table tops that can be locked in place in at different heights according to the use. The lowest setting being used as a more traditional table with adjustment based on height or age of users. The variable table tops allow the users to adjust to different levels for display at the farmers market or similar events. The material proposed is red oak waste from the Coastal Studio Gridshell in Cheticamp. The table tops consist of the waste wood from the scarf cuts while the rest of the table can be constructed with the disregarded wood from worm holes and knots.
