reflections



 So at the conclusion of this project there are many things that come to mind:-
The maker culture falls into different categories. By categories I am speaking not so much about the actual ‘products’ that are created or produced, as the demographics. There has always been a maker culture, but the last 40 – 50 years has seen a significant decline, I will venture to suggest, as the consumer culture grew and became more invasive in our society, many more things were made commercially to entertain (distract) us and for us to buy and use.  With the economic meltdown since 2008 there has been a remarkable surge in the maker culture due in part to people having to look to other ways to make (no pun intended) a living, and in part to the incredible advances in computers, software and the manufacturing equipment associated with this.
I have always considered myself as a maker but this has had high and low points through my life. In younger years I was always interested and active in making things; things that required research, technical understanding and construction (a particular point in high school). School shop projects, model railways, aircraft, boats and of course painting and drawing, were all in the spectrum. Working life resulted in a decline primarily to time availability but this came back to some degree when my own children became part of my life, only to decline again as they grew older, entered the workforce and indeed appear to go through the same cycle. The only difference, fundamental difference, is that they are children of the Electronic Age and firmly part of that demographic.
Of later years, I have become more active in the maker culture and this particular project has brought me back closer to that, re-kindling an interest. With my generation and the following one (baby boomers I believe) we have the time to revisit this and even revive some of the older crafts. The generation subsequent to this are finding themselves displaced before they are ready or willing to retire and caught between the old and new (digital) manufacturing technologies. They are however finding new ways to make a living, drawing from their life experiences and the extremely user friendly new technologies. The younger generations who have grown up with this new technology have found new ways to be entrepreneurial with it and create a new industrial/consumer age albeit on smaller individual scales and in concert with the new technology.
The opportunity to make this object, a pantograph, really stimulated my interest. The origins of the instrument, of which I was unaware, went back 400 hundred years and the inventor was an accomplished individual. Christopho Scheiner could be paralleled to     da Vinci judging from his CV which has been compiled by Richard S. Westfall for the Galileo project. Scheiner invented the pantograph in 1604 and details of his invention were published in 1631 in a pamphlet entitled Pantographice seu ars delineandi. The isometric drawing of Scheiner’s pantograph is part of the publication and while there are many images of this instrument online today, the original drawing provided the design that I chose to work to. What was of immediate interest was the access to original documents/design that was five centuries old and this was possible through the Web; Chris Anderson states in his book Makers: The New Industrial Revolution “The past ten years have been about discovering new ways to create, invent, and work together on the Web” (32). I have no idea how I would found so much information, original sources, so quickly and relatively easily, without the Web. While in the past information was recorded but not necessarily readily available in an accessible fashion, the Web has certainly changed this in reality for the better. There have been times in the past where information or knowledge was restricted, controlled and while that can still be an issue today, the Web and the Internet have broken down barriers and disseminated infinitely greater amounts of information and knowledge to far wider audiences than ever before. Aldus I am sure would be happy to see this today; as he said in 1496 “My only consolation is the assurance that my labors are helpful to all, and that the fame and use of my books increase from day to day, so that even the ‘book buriers’ are now bringing their books out of their cellars and offering them for sale” (Barolini, H. 30)
With  a re interpretation of the drawing I was able to produce a technical drawing that allowed me to seek out present day materials that would permit me to reproduce Scheiner’s instrument as close to original as possible. During the process of material selection at the local hardware store I found that dimensions of the arms would be difficult to handle in the manufacture and risk distortion in the final object, so I selected a different size of material to overcome this issue. The basic process of manufacture was relatively straight forward; the measuring, cutting and drilling tools that I have available were quite adequate for the tasks however despite careful application I did encounter some control and accuracy issues. On reflection a mitre box and better clamping tools would have been an asset and actually access to a drill press would have permitted greater control over that process. In addition, more control over the manufacturing process would have been possible if I had used a harder wood; the wood that I selected was softer and this caused more drift in the cutting and drilling process.
All in all however, I have achieved the construction of a working Pantograph based on Chistopho Schnieder’s original design using readily available modern day materials reapplied to a 17th century design which in turn was available through the internet. An interesting and informative exercise that has afforded me an opportunity to research and make an object that I otherwise would have not have pursued; these days I normally use digital photography, projection and Google Sketchup, coincidentally all part of the digital world that we now inhabit.

The original pantograph was originally built of wood. Arms, pins, styluses and guide were all made of wood as this would have been more readily available and cheaper; metal was somewhat scarcer and directed to more strategic purposes.
My approach is to build a wooden device although I may have to use metal split pins or cotter pins to keep the wooden pins in place. Originally the only metal that would have been used would have been in the drawing point and Silverpoint would have been employed for its drawing qualities and durability.
While later versions of pantographs would have used metal, my options are limited in terms of construction. I do not have access to a metal shop which would be necessary if was using metal materials. I do have adequate tools to construct in wood in my own space.
From my second iteration drawing, I have decided to use larger section of wood for the arms, 11/2 by ¼   which will offer more strength and rigidity. 6 feet of this wood, 3 feet of 5/8 dowel and 3 feet of 3/8 dowel will provide enough material to construct the entire device and the drawing point will be either a graphite pencil or drawing pen with a reservoir of ink.
The construction will involve measuring, cutting, drilling and assembly which will require some gluing. So the tools required will be rulers, saw, power drill, sandpaper and glue, all of which I have available in my toolbox. This is also a driver to use wood which is easier work with.

Now I am at the first iteration model stage. Using mat board strips and stick pins the first stage can be tested
And I have now a full scale drawing of Scheiner's Pantograph which a reproduction  can be built from.

The full scale drawing is difficult to see so I will have that at class today.

This is a preliminary sketch for the first construction. I am thinking that it would be kind of interesting to actually try to build one from Christofe Scheiner's original 1603 drawing


Christopher Scheiner was a 16th century Jesuit priest, physicist and astronomer and in 1603 invented the Pantograph. The name Pantograph is derived from the Latin Pantographice but finds its roots in the Greek pas or pantos, topos and graphé which in English is all, place, and draw or write.(1)
The Pantograph would appear to have been developed originally to copy or reproduce original drawings or designs in different scales. Mechanical Printing and Copperplate Etchings had appeared in Germany in the 1400's which allowed reproductions of text and intricate drawings, but reproducing basic drawings in different scales required a different type of mechanical device; the lever had to be able to follow a parallel track to the original and it was through a parallelogram device that this was developed by Scheiner.
The original was made of hardwood, metal was still scarce an expensive but later and especially in the Industrial Revolution the device was made more durable and versatile with metal. 


It was with the development of the Industrial Revolution in the 18th century that the pantograph found its important place both as a drawing instrument and a manufacturing tool. Accurate, scaled drawing reproductions and machine profiling was the Pantograph’s domain until the development of computers took over with Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) in the 1970’s.
Interestingly enough it was James Watt, the designer and builder of the first steam engine, the birth of the Industrial Revolution, who developed a 3D Pantograph to sculpt 3D forms   with machine cutters. In the early 19th century Benjamin Cheverton improved the process by using machine rotary cutters which allowed even more precise profiling.
Today it is the computer and its programs that control machines to produce 3D shapes and forms with the latest development being the 3D printer and/or rapid profiling techniques for applications across industry and services.
