Upon leaving the radio control industry in the ‘s he began as an importer for small lathes from Australia that were to be sold by Sears under the Craftsman name. He also marketed the tools himself under the Sherline name and eventually began producing them in the United States in , having purchased the rights to do so. Expanding the tool and accessory line over the years has given him an appreciation for what these early manufacturers had to deal with in the design, production and marketing of small tools. A few years ago Joe began purchasing small tools as he found them available at shows or auctions. Several have since been donated by other patrons who appreciate small tools and want share them with others. This is just the basis of a good tool collection. The foundation plans to continue to add to this collection as interesting machines become available. Seeing the tools in person is an interesting walk through history, from the first simple hand-cranked watchmaker lathes to the electronically speed controlled, laser engraved machines made today.
At this era — of Stickley’s operations, his designer, Lamont Warner , lays out the “heavy” versions of the initial Stickley turn toward the quarter-sawn white-oak furniture with the exposed tenons, tenons-and-keys, corbels, and so forth, that distinctively mark his “signature” products for the rest of his activity as a furniture manufacturer. Read more here and here. In both its format and its contents, Catalogue D is a definite departure, indicative of a major revison of company policy.
As his chief biographer, David Cathers, notes, Stickley’s earlier catalogs and promotional booklets have a more pedestrain flavor: The covers are gray and rather industrial looking, while pages inside are filled with business-like black-and-white photos. Lacking in these black-and-white images, of course, are the rich brown hues and textures of the actual wood.
The vendor had a sticker on it mentioning the date of A cursory look over, the frog surface, the dates of patents on it, no frog screw adj, low knob etc, all pointed toward the same vintage, so I did not questioned it, I just quickly look up where falls in the Type study: Type 9 and proclaimed it earlier in a previous post. Now lets see if the seller and I still agree when looking closer.
Mine is corrugated so it cannot be before The vast majority of Type category pretty well all start with a sentence like: All the features of the previous, except: That means we have to look back in order to see what else to look for.

Evolution[ edit ] A selection of prehistoric stone tools. Archaeologists classify stone tools into industries also known as complexes or technocomplexes  that share distinctive technological or morphological characteristics. They were not to be conceived, however, as either universal—that is, they did not account for all lithic technology ; or as synchronous—they were not in effect in different regions simultaneously. Mode 1, for example, was in use in Europe long after it had been replaced by Mode 2 in Africa.
Clark’s scheme was adopted enthusiastically by the archaeological community. The transitions are currently of greatest interest. Consequently, in the literature the stone tools used in the period of the Palaeolithic are divided into four “modes”, each of which designate a different form of complexity, and which in most cases followed a rough chronological order.

The stylistic techniques used to date formal furniture such as Chippendale and Hepplewhite simply does not work for American country and primitive furniture. Country furniture does have its styles based predominately on religion and region. The catholic French and the Irish built cupboards with bold moldings, cut out feet, raised panels and they painted their cupboards in bright colors. The puritan New England cabinetmakers built simple unadorned cupboards painted in drab colors.
However, this factory at New State Road south of the Knorr Street gate is a shell of the once mighty Disston and Sons Keystone Saw Works. 4 1 Harry C. Silcox, ” Henry Disston and Sons The Rise and Fall of America’s mightiest Saw Works,” unpublished manuscript, (Philadelphia, ).
Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things.
Carbon is a radioactive isotope of carbon. The half-life of carbon is approximately 5, years.

I am putting up what information I have, with pictures, as a resource for anyone interested in collecting saw sets as a hobby or as a general resource for anyone of interest. There are presently over pictures of different patented and non-patented saw sets on this site. This is not intended to be a price list, so if that is why you came, have fun looking at the pictures.
The tool is a caliper, graduated to 8 inches, but who cares, the form is everything. There are two horse heads facing away from each other that form the top of the tool. The patina is lovely.
Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.
As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.
These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists. Geochronologists do not claim that radiometric dating is foolproof no scientific method is , but it does work reliably for most samples.
It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for “young Earth” theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.

Our research activity can be thematically structured into four different main topics: Awareness building, tool and methods development, product improvement and environmental communication.
What is relative dating? Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc. This technique does not give specific ages to items. It only sequences the age of things or determines if something is older or younger than other things. Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
Seriation uses the assumption that once a tool was developed, its use would become more widespread. Stratigraphy uses the assumption that higher layers or strata were laid down after lower layers.
