SET 1 – HLT Remodel: 4-20-2023
We’ll keep exploring the new electronics area here in a moment, but I wanted to briefly spin around first and show y’all the new center actionway of the store, which at this point had become fully completed! Remember, this entire actionway was shifted, and as you might can guess, the ultimate goal of that work was so that it would make the new electronics department visible even from the front end of the store (as it aligns perfectly with this actionway). You can see some swaths of empty space towards the middle of the pic where the blue world departments hadn’t yet shifted to accommodate their new extra space; and on my left, we actually (finally!) get to see a tiny portion of the temporarily relocated storage bin/trash can shelving, placed atop the former shoe department carpeting (surprisingly one of only two good views I ever got of this…)

These megalith alignments, contemporary to those (more famous) of Carnac, show that the Crozon peninsula was inhabited since many thousands of years. The standing stones date from about 2500 BC. In the beginning there were probably more than 400 stones; today there are only 65 left, arranged in three lines that form three of the four sides of a rectangle. The longest line is about 200 m. It is assumed that the arrangement had an astronomic significance related to the constellation of Pleiades whose name in Breton is “ar yar” (the hen), hence the name of the place derived from “Lagad-Yar” (hen’s eye).

Aliniamentele de megaliţi, contemporanele cu cele (mai cunoscute) de la Carnac, aratǎ cǎ peninsula Crozon a fost locuitǎ de mai multe mii de ani. Menhirele dateazǎ din anii 2500 î.Ch. Iniţial, în amplasament s-au aflat probabil peste 400 de pietre; astǎzi au mai rǎmas 65, dispuse în trei linii formând trei din laturile unui dreptunghi. Cea mai lungǎ dintre ele are cca. 200 m. Se presupune cǎ amplasamentul a avut unele semnificaţii de naturǎ astronomicǎ, fiind legate de constelaţia Pleiadelor, purtând în bretonǎ numele de “ar yar” (gǎina), de unde şi numele locului derivat din “Lagad-Yar” (ochiul gǎinii).

Spinning is an ancient textile art in which plant, animal or synthetic fibers are drawn out and twisted together to form yarn. For thousands of years, fiber was spun by hand using simple tools, the spindle and distaff. Only in the High Middle Ages did the spinning wheel increase the output of individual spinners, and mass-production only arose in the 18th century with the beginnings of the Industrial Revolution. Hand-spinning remains a popular handicraft.
Characteristics of spun yarn vary according to the material used, fiber length and alignment, quantity of fiber used, and degree of twist.
HISTORY
HAND SPINNING
The origins of spinning fiber to make string or yarn are lost in time, but archaeological evidence in the form of representation of string skirts has been dated to the Upper Paleolithic era, some 20,000 years ago. In the most primitive type of spinning, tufts of animal hair or plant fiber are rolled down the thigh with the hand, and additional tufts are added as needed until the desired length of spun fiber is achieved. Later, the fiber is fastened to a stone which is twirled round until the yarn is sufficiently twisted, whereupon it is wound upon the stone and the process repeated over and over.
The next method of spinning yarn is with the spindle, a straight stick eight to twelve inches long on which the yarn is wound after twisting. At first the stick had a cleft or split in the top in which the thread was fixed. Later, a hook of bone was added to the upper end. The bunch of wool or plant fibers is held in the left hand. With the right hand the fibers are drawn out several inches and the end fastened securely in the slit or hook on the top of the spindle. A whirling motion is given to the spindle on the thigh or any convenient part of the body. The twisted yarn is then wound on to the upper part of the spindle. Another bunch of fibers is drawn out, the spindle is given another twirl, the yarn is wound on the spindle, and so on.
The distaff was used for holding the bunch of wool, flax, or other fibers. It was a short stick, on one end of which was loosely wound the raw material. The other end of the distaff was held in the hand, under the arm or thrust in the girdle of the spinner. When held thus, one hand was left free for drawing out the fibers.
A spindle containing a quantity of yarn rotates more easily, steadily, and continues longer than an empty one; hence, the next improvement was the addition of a weight called a spindle whorl at the bottom of the spindle. These whorls are discs of wood, stone, clay, or metal with a hole in the center for the spindle, which keep the spindle steady and promote its rotation. Spindle whorls appeared in the Neolithic era. They allowed the spinner to slowly lower, or drop, the spindle as it was spinning, thus allowing a greater quantity of yarn to be created before it had to be wound onto the spindle; hence the name "drop spindle," which is now most commonly used for the hand spindle with whorl attached.
In mediæval times, poor families had such a need for yarn to make their own cloth and clothes that practically all girls and unmarried women would keep busy spinning, and "spinster" became synonymous with an unmarried woman. Subsequent improvements with spinning wheels and then mechanical methods made hand-spinning increasingly uneconomic, but as late as the twentieth century hand-spinning remained widespread in poor countries: in conscious rejection of international industrialization, Gandhi was a notable practitioner. The hand spinning movement that he initiated as a part of the Indian freedom struggle has made the handwoven cloth known as "Khadi" made from handspun cotton yarn world famous. Women spinners of cotton yarn still continue to work to produce handspun yarn for the weaving of Khadi in Ponduru, a village in South India.
A great wheel (also called a wool wheel, high wheel or walking wheel) is advantageous when using the long-draw technique to spin wool or cotton because the high ratio between the large wheel and the whorl (sheave) enables the spinner to turn the bobbin faster, thus significantly speeding up production.
A Saxony wheel (also called a flax wheel) or an upright wheel (also called a castle wheel), can be used to spin wool or cotton, but are invaluable when spinning flax (linen). The ends of flax fibers tend to stick out from the thread unless wetted while being spun. The spinner typically keeps a bowl of water handy when spinning flax, and on these types of wheels, both hands are free (since the wheel is turned with a treadle, rather than by hand), so the spinner can use one hand to draft the fibers and the other to wet them.
INDUSTRIAL SPINNING
Modern powered spinning, originally done by water or steam power but now done by electricity, is vastly faster than hand-spinning.
The spinning jenny, a multi-spool spinning wheel invented c. 1764 by James Hargreaves, dramatically reduced the amount of work needed to produce yarn of high consistency, with a single worker able to work eight or more spools at once. At roughly the same time, Richard Arkwright and a team of craftsmen developed the spinning frame, which produced a stronger thread than the spinning jenny. Too large to be operated by hand, a spinning frame powered by a waterwheel became the water frame.
In 1779, Samuel Crompton combined elements of the spinning jenny and water frame to create the spinning mule. This produced a stronger thread, and was suitable for mechanisation on a grand scale. A later development, from 1828/29, was Ring spinning.
In the 20th century, new techniques including Open End spinning or rotor spinning were invented to produce yarns at rates in excess of 40 meters per second.
CHARACTERISTICS OF SPUN YARNS
MATERIALS
Yarn can be, and is, spun from a wide variety of materials, including natural fibers such as animal, plant, and mineral fibers, and synthetic fibers. It was probably first made from plant fibers, but animal fibers soon followed.
TWIST AND PLY
The direction in which the yarn is spun is called twist. Yarns are characterized as S-twist or Z-twist according to the direction of spinning (see diagram). Tightness of twist is measured in TPI (twists per inch or turns per inch).
Two or more spun yarns may be twisted together or plied to form a thicker yarn. Generally, handspun single plies are spun with a Z-twist, and plying is done with an S-twist. This is a cultural preference differing in some areas but surprisingly common.
PLYING METHODS
Yarns can be made of two, three, four, or more plies, or may be used as singles without plying. Two-ply yarn can also be plied from both ends of one long strand of singles using a center-pull ball, where one end feeds from within a ball of yarn while the other end feeds from the outside. So-called "Andean" plying, in which the single is first wound around one hand in a specific manner that allows unwinding both ends at once without tangling, is another way to ply smaller amounts of yarn. The name comes from a method used by Andean spinners to manage and splice unevenly matched singles being plied from multiple spindles. "Navajo" (aka "chain-") plying is another method of producing a three-ply yarn, in which one strand of singles is looped around itself in a manner similar to crochet and the resulting three parallel strands twisted together. This method is often used to keep colors together on singles dyed in sequential colors. Cabled yarns are usually four-ply yarns made by plying two strands of two-ply yarn together in the direction opposite to the plying direction for the two-ply yarns.
CONTEMPORARY HAND SPINNING
Hand-spinning is still an important skill in many traditional societies. Hobby or small scale artisan spinners spin their own yarn to control specific yarn qualities and produce yarn that is not widely available commercially. Sometimes these yarns are made available to non-spinners online and in local yarn stores. Handspinners also may spin for self-sufficiency, a sense of accomplishment, or a sense of connection to history and the land. In addition, they may take up spinning for its meditative qualities.
Within the recent past, many new spinners have joined into this ancient process, innovating the craft and creating new techniques. From using new dyeing methods before spinning, to mixing in novelty elements (Christmas Garland, eccentric beads, money, etc.) that would not normally be found in traditional yarns, to creating and employing new techniques like coiling, this craft is constantly evolving and shifting.
To make various yarns, besides adding novelty elements, spinners can vary all the same things as in a machined yarn, i.e., the fiber, the preparation, the color, the spinning technique, the direction of the twist, etc. A common misconception is yarn spun from rolags may not be as strong, but the strength of a yarn is actually based on the length of hair fiber and the degree of twist. When working with shorter hairs, such as llama or angora rabbit, the spinner may choose to integrate longer fibers, such as mohair, to prevent yarn breakage. Yarns made of shorter fibers are also given more twist than yarns of longer fibers, and are generally spun with the short draw technique.
The fiber can be dyed at any time, but is often dyed before carding or after the yarn has been spun.
Wool may be spun before or after washing, although excessive amounts of lanolin may make spinning difficult, especially when using a drop-spindle. Careless washing may cause felting. When done prior to spinning, this often leads to unusable wool fiber. In washing wool the key thing to avoid is too much agitation and fast temperature changes from hot to cold. Generally, washing is done lock by lock in warm water with dish-soap.
EDUCATION
There are number of guilds and educational institutions which offer certificate programs in handspinning. The Handweavers Guild of America (HGA) offers a Certificate of Excellence in Handspinning. Olds College in Alberta, Canada, offers a Master Spinner program both on campus and by distance education. The Ontario Handweavers & Spinners offer both a Spinning Certificate as well as a Master Spinning Certificate. These programs feature in-depth examinations of handspinning topics, as well as extensive assignments and skill evaluations.
TECHNIQUES
A tightly spun wool yarn made from fiber with a long staple length in it is called worsted. It is hand spun from combed top, and the fibers all lie in the same direction as the yarn. A woolen yarn, in contrast, is hand spun from a rolag or other carded fiber (roving, batts), where the fibers are not as strictly aligned to the yarn created. The woolen yarn, thus, captures much more air, and makes for a softer and generally bulkier yarn. There are two main techniques to create these different yarns: short draw creates worsted yarns, and long draw creates woolen yarns. Often a spinner will spin using a combination of both techniques and thus make a semi-worsted yarn.
Short draw spinning is used to create worsted yarns. It is spun from combed roving, sliver or wool top. The spinner keeps his/her hands very close to each other. The fibers are held, fanned out, in one hand, and the other hand pulls a small number from the mass. The twist is kept between the second hand and the wheel. There is never any twist between the two hands.
Long draw is spun from a carded rolag. The rolag is spun without much stretching of the fibers from the cylindrical configuration. This is done by allowing twist into a short section of the rolag, and then pulling back, without letting the rolag change position in one's hands, until the yarn is the desired thickness. The twist will concentrate in the thinnest part of the roving; thus, when the yarn is pulled, the thicker sections with less twist will tend to thin out. Once the yarn is the desired thickness, enough twist is added to make the yarn strong. Then the yarn is wound onto the bobbin, and the process starts again.
SPINNING IN THE GREASE
Handspinners are split, when spinning wool, as to whether it is better to spin it 'in the grease' (with lanolin still in) or after it has been washed. More traditional spinners are more willing to spin in the grease, as it is less work to wash the wool after it is in yarn form. Spinners who spin very fine yarn may also prefer to spin in the grease as it can allow them to spin finer yarns with more ease. Spinning in the grease covers the spinner's hands in lanolin and, thus, softens the spinner's hands.
Spinning in the grease works best if the fleece is newly sheared. After several months, the lanolin becomes sticky, which makes the wool harder to spin using the short-draw technique, and almost impossible to spin using the long-draw technique. In general, spinners who use the long-draw technique do not spin in the grease.
Such spinners generally buy their fibers pre-washed and carded, in the form of roving, sliver, or batts. This means less work for the spinners, as they do not have to wash out the lanolin. Spinners then have available predyed fiber, or blends of fibers, which are hard to create when the wool is still in the grease. As machine carders cannot card wool in the grease, pre-carded yarn generally is not spun in the grease. Some spinners use spray-on lanolin-like products to get the same feel of spinning in the grease with carded fiber.

You may see layer alignment issues on prints with flat surfaces; notice how the print on the left exhibits the problem very well but the contour of the print on the right masks the problem to a certain degree. This can be caused by a variety of issues, but here are some of the things you can do to get more consistency:
1. Slow down if using non-Marlin firmware. Print your perimeter at 20-25 mm/sec
2. Tighten your belts.
3. Make sure any springs on your build platform are very tight and that the top plate can't wobble around independent of the bottom plate.
4. Upgrade your Z-coupling to a better one, such as www.thingiverse.com/thing:11220
5. Replace any non-straight threaded rod used in the Z-axis with perfectly straight ones.
6. Unless they were printed perfectly, replace your timing pulleys with manufactured ones, such as sdp-si.com/eStore/PartDetail.asp?Opener=Group&PartID=...

I decided to make my own dropout alignment tools. The Park ones have the annoying feature of moving around in the dropout while you're trying to tighten them down. The Stein ones solve this by using quick-release clamps, but then require you to adjust the spacing with a difficult-to-use collar instead of a screw thread (and they cost 3x as much). So here's the best of both worlds: quick-release clamps, long arms, and a nice tight screw thread adjustment.
