Drill Press

If you think you already have everything in your toolbox, think again. Have you checked your toolbox yet? Do you still have your drill press around?

Have you checked your toolbox lately? Do you have a drill press in it? A drill press is a permanent style of drill that may be mounted on a stand or bolted to the floor or workbench. Drill presses let you drill holes in metal, wood and a variety of other materials. There are several important pointers to be considered before buying drill presses.

There are two types available in the market of drill presses. The floor-standing drill press models that tender more power and can typically handle a wider range of materials and the bench-top drill press models that are a lot more compact and they tend to be a little less expensive. They are best apposite for smaller work pieces and less demanding jobs.

Did you know that in terms of swing the size of a drill press is typically measure? Like the bench-top model that typically has a swing of 10" to 12" and it has a capacity that is larger that needs more powerful motor while a floor-standing model has a swing between 15" and 17" that can have one half to three fourth horsepower. Another capacity that you might consider is the quill stroke because it determines how deep you can drill.

You may like to consider a radial press or magnetic press depending on your drilling needs. A radial press is best if you do a lot of angled drilling or you do work with very large items. A magnetic drill press gives enormously powerful operation along with easy portability.

If you cannot afford to buy brand new hand drill press, you can always buy second hand drill presses. You just need to be a little careful about the product and the accessories that come along with it. Please take note that drill presses are available with variable power, attachments and sizes. This will provide certain handy tips and will direct you to the right path in choosing the best-used drill press. First, you make sure that drill press works effortlessly without any hiccups, makes sure that it makes precision holes and look out for the maximum power that is made by the motor. Secondly if you are going to drill through tougher material you have to get a drill press with higher horsepower. Drill presses have horsepower from ¼ to 1 horsepower. Thirdly, try drilling holes before making up your mind, also take care that the drill press does not unreasonably heat up or stops rapidly while working.

Then, glimpse if any warranty is still left on the drill press, the more the better and the less the more you should bargain. There are also factory reconditioned drill presses available from different brands; this could also be an exciting basis of getting used drill press and if you don't have any ideas or clues and you are in dire need of a used drill bit always ask someone that is an expert or professional in selling with such tools to make up your final choice. These drilling machines also known as the drill presses are used to make holes in metal with a twist drill. To perform the following basic hole machining operations like tapping internal threads with a utilizing tapping attachment, countersinking, reaming, boring and counter boring, a diversity of other cutting tools are also used. Reamer is a modular design with replaceable cutting head, and easy to change while still in the machine tool spindle.

Types Of Drill Bits

Drill bits are tools used in making cylindrical holes. Various types of drill bits are designed for different uses.

Drill bits are equipments or tools that are used in making cylindrical holes. Drill bits can also be referred to as a drilling machine. Drill bits are available in various drill types such as metal drills, gun drills, screw machine drills, core drills, step drills, spade drills, forstner drills, masonry drills, dental or surgical drills, wood bits, twist drills, drill blank taper drills and much more.

They are designed to cut while doing a clockwise rotating motion. Several drill bits are coolant fed. They contain a channel or hole for directing the coolant fed near to the cutting edges. The split point drill heads of drill bits are used for chip clearance and for excellent centering. Drill bits can also be used in cutting aluminum, general-purpose metals, brass, copper, bronze, ceramic, and plastic, stainless steel, steel, wood, titanium and hardened materials. Various types of drill bits are designed for different uses.

Listed below are some types of Drill Bits.

Twist Drill: It drills holes in plastic, metal and wood. This drill is currently produced with a width covering a range from 0.05 millimeters to 100 millimeters while its length is around 1000 millimeters. The most usual twist drill has a tip angle of 118 degrees. This is a proper angle for an extensive array of job. It also has a long series drill for extended length twist drills. It is not advisable to drill deep holes using this twist drill.

Diamond Drill Bit: This particular drill is used in the bathroom for updating or remodeling. It is also used in redesigning your kitchen decoration. Furthermore, it is used on ceramic, glass, tile, limestone, stained glass, marble, fiberglass, porcelain, stone, slate and porcelain tile. When using this drill, the main concern is to obtain water at the edge of the drill bit. Drilling fiberglass may be done with or without water but make sure that the fiberglass has ample amount of water just to get the drill wet.

Indexable Drill Bit: This provides an excellent performance in making short-hole drillings. Stainless steel is drilled 3x in diameter and only a short-hole must be done.

Listed below are some other types of drill bits

• Adjustable Bit: This is built with a changeable cutter blade to bore holes of various sizes. It is also used for drilling gaps for wiring or piping.

• Around-the-corner bit: It is used to cut arched holes that are stretched in corners with a diagonal cutting surface.

• Auger Bits: This drill creates drill holes in wooden materials. The drill ends have a screw head so that the bits may be self fed.

• Brad-point drill: This drill looks almost the same as the usual bits but it has sharpened point to make wood drilling a lot easier. This drill has cleaner holes other than spade bits.

• Counterbore: The drill allows a screw to be driven under the wood outside. The holes that are drilled may be filled with a plug or wire.

• Drill Saw Bit: It is used to cut holes such as wood and metal and can enlarge current holes.

• Countersink: A drill that has an angled tip design that forms a "slump" in the screw head.

• Fly cutter: This one is often used to cut circles in wood and other soft metals. The diameter of circles may be adjusted by changing the cutter blade setting.

• Hole saw: It cut holes from one to six centimeters in diameter and has a center bit for directing the cutting blade edge of the saw.

• Reamer bit: The tapered bit of reamer may be used on existing holes rather than to enlarge holes.

• Screw pilot bit: This beautiful bit is used for drilling body holes. A pilot hole is used along with the countersink.

• Wire Brushes: It use to remove rust and to clean up metal and is available either as a wheel or a cup with wire brush.

• Plastic bit: This is designed with a tip so as to prevent splintering when drilling plastic. It is important to reduce the speed and slowly drill the other side of the plastic.

• Plug cutter: Use this to remove cylindrical shapes from the wood. It covers the screw using a small cylindrical plug.

Tips For Tennis Shoes Maintenance

Tennis shoes are now used extensively in other sports such as basketball, jumping and running even though it was originally designed for Tennis. A bit more expensive than normal shoes, tennis shoes require extensive care to last for longer. Here are a few handy tips on how to take care of your tennis shoes.

Clean is keen:

When it comes to tennis shoes, clean is keen-should be the motto. Try your best to keep your tennis shoes from getting dirty. Regular cleaning is a must, weekly washing and thorough drying will help to keep your tennis shoes clean.

Be careful with the fabric:

Watch out for the material of your tennis shoes while cleaning. Tennis shoes made of synthetics are all right for washing. It`s important clean your tennis shoes immediately after getting them dirty, because the strain might be difficult to let go if they stay for longer period and get dried. Tennis shoes of canvas material are easier to clean, just rinse them well with warm water and let them dry properly.

Deodorize your tennis shoes:

Keeping your tennis shoes from smelling bad can be an arduous task. However, there are tips which help your tennis shoes from smelling bad. It`s a good and inexpensive way to dry the smelly tennis shoes in the sun as that will reduce the stink smell to a large extent. You can sprinkle baking soda into the tennis shoes as that will absorb the moisture and helps preventing the smell. Rubbing alcohol spray onto the tennis shoes is a very effective way to prevent the bad smell. However, as they say prevention is better than cure; similarly regular spraying of anti-fungal foot spray into your tennis shoes prevents them becoming smelly.

Tips to wash in washing machine:

Washing your tennis shoes in washing machine helps in letting go of the horrible smell. However, some points ought to be considered while washing your favourite shoes in washing machine. Always opt for warm water for washing.

Tennis shoes of quality brands won`t suffer any damage from this washing, but it`s a good idea wash mid standard shoes along with regular white load as the soft material of towels etc. will provide a sort of cushion to the shoes as they tumble. Before washing, make sure to remove the laces and insoles out of your tennis shoes to prevent them from tangling up in the agitator. After washing, put them out in the sun to dry. This is an inexpensive method to get all new looking tennis shoes.

Benefits of using shoe cleaner:

For the longevity of your tennis shoes, it`s a good idea to use shoe cleaner such as Sport Shoe Stuff Scrub-Off Heavy Duty Cleaner. Some washing liquid and liquid bleach can also be used for giving your tennis shoes a shiny look.

Drying plays an important role:

After washing your tennis shoes, it`s good to dry it in the sun. However, I recommend drying them in a well-ventilated area at room temperature. Dry your wet tennis shoes with a white towel. For next phase of drying, stuff the tennis shoes with white porous paper (don`t go for newspaper as it can bleed ink) or a quick dry towel, but before that make sure to remove the shoe pad, sock-liner or orthotics from your tennis shoes. Replacing the paper towels in regular interval will help letting go of the extra water if any.

Storage of tennis shoes:

Storage of your tennis shoe is also very important as cleaning them. Always keep your tennis shoes in a dry, cool place. Wooden or plastic shoe shapers are ideal to keep tennis shoes.

Follow the above mentioned tips to preserve your expensive tennis shoes for a longer period.

Six Tips for Binding Documents With Spiral Coil

Spiral coil binding is one of the most popular binding styles used today. It offers a contemporary look and feel with some great features such as full three hundred and sixty degree rotation. However, binding documents with spiral coil can be a little bit tricky, especially if you have never done it before. This article will provide you with six simple tips for binding your documents with spiral coil. Here they are.

1. There are several different hole patterns used for spiral coil binding. The most common hole pattern is 4:1 pitch (four holes per inch). However, spiral coil spines are also available in 5:1 pitch (five holes per inch) and in 3:1 pitch (three holes per inch). More than 90% of users choose a 4:1 pitch machine since the supplies are easier to find and less expensive. However, it is also important to note that some 4:1 pitch punches use a 43 hole pattern while others use a 44 hole pattern. If you decide to order pre punched covers or need to match a hole pattern from an existing document you will need to count the holes to make sure that you end up with the appropriate number of holes.

2. Using oversized covers with your coil binding machine is not recommended. In fact, many coil binding machines are not capable of handling oversized covers. When you try to punch an oversized cover with a coil binding machine the holes may not line up with the paper that you have punched or you may end up with extra holes.

3. Most coil binding machines do not have fully disengageable dies. This means that you can not choose to stop a single pin from punching. This makes it difficult to bind odd sized books and documents with your machine. Most coil binding machines are capable of binding letter and half letter sized documents. If you are going to need to bind smaller or larger documents, it is recommended that you choose a machine with fully or partially disengageable dies.

4. Once you have the holes punched in your document you will need to spin the coil onto the spine of your book. Start by taking the spiral coil and spinning through the first few holes of the document by hand. If you have a machine with a spiral coil inserter on it, you can use the roller from your inserter to spin the element the rest of the way onto the document. However, be careful that you don’t spin the book right off the other side. If you don’t have an electric inserter, you will need to simply spin the coil onto the book by hand.

5. The final step in finishing a book bound with spiral coil is to crimp the ends of the coil so that the spiral doesn’t spin back off the book. Special coil crimping pliers are used to cut off the excess coil and bend over the end in a single step. It is possible to achieve the same results using a pair of needle nosed pliers but it is much more difficult and will require multiple steps. If you do have a pair of crimping pliers it is important to remember two things. The red dot should always face the ceiling and the spine of the book should always face towards you.

6. Binding documents that are less than one inch thick is fairly simple with colorcoil. However, binding documents that are larger than an inch can be somewhat difficult. In order to bind larger documents you will need to form the spine of the document so that it matches the curved shape of the coils that you are planning to insert. Most coil binding machines have a spine shaper built into them. However, if you are planning on binding lots of thick documents using coil you might want to consider buying a stand alone spine forming device. You should also note that you most likely will not be able to use your coil inserter for thicker documents. You will need to spin the coils on by hand.

These are five simple things to remember when binding documents with spiral coil binding. Good luck and happy coilbinding.

Machine Quilting Designs

Quilting , like painting is a wonderful art. It is similar to painting in the sense that paints and brushes are replaced by threads and needles. Paper is replaced by fabrics. Quilts were traditionally made by hand, but not with the advent of sewing Quilting machines, many prefer to use machines. This is because, machines make Quilting work easier, faster and not to mention a lot neater. You have the option of using an ordinary sewing machine which has Quilting capabilities or you can use a machine that is specifically designed for Quilting .

Small patches of different fabrics are used to make quilts, though you can use the same fabric as well. It's really interesting and can be likened to working on a jig saw puzzle. Only difference is, in a quilt you need to stitch up the entire thing. Quilting as a craft has been around since many years. Some quilts are passed down to generations, and there are many happy memories associated with these quilts.

If you're a beginner and your interested in Quilting , you can start off by using two or more different fabrics. Basically, you should start collecting left over fabrics or materials that has remained from previous stitching. Once you've collected these, you can then start by sewing all of these together. You should be able to use the sewing machine quite adeptly. It's advisable that you practice using the sewing machine, as much as you can, as handling the machine while Quilting is no easy task. You could also create designs of the quilt. Start with simple, basic designs, and then once you have enough experience, you can move to more complex designs. The Internet has a number of sites where you'll be able to get some free Quilting designs. If these seem too complicated, you can just get some ideas and create your own unique designs.



Quilt designs
need creativity , so make sure you gear up all your creativity while your Quilting . You can create various designs on a quilt, it could be floral designs, geometrical patterns, landscapes, plaids etc. Basically, the choice is so much, you can choose whatever design you think you could work with. If you're new to Quilting or Quilting designs, you can try out mini or miniature quilts with easy designs. There's no hard and fast rule that it has to be a large quilt. Once you gain experience, you can move to larger quilts. It's basically up to you, and what your comfortable with.

Once you decide on a design, the next step is to draw it on a fabric and cut it out. Place these cut out designs on the quilt in the way that you want it to. Mark these designs using pins on the quilt, or you could also run a needle (without a thread) around the designs. This creates an impression of dotted marks, which will then make the Quilting process much easier.

You can choose from an extensive range of colors to make your quilt. Generally a single color is not used for a quilt. Multiple colors are used, which make the quilt attractive and unique. Choosing colors may seem simple, but its important that you choose the color after giving it some consideration. Think of the colors of your bedroom and what would blend in. You can also think of cool and soothing color tones. For a guest room, a brighter color will work great, as they can enjoy your handiwork.

People generally design a quilt on a certain theme. Quilting the theme is the toughest part though. The designs have to fit into the main theme that you have chosen. For example, if your making a quilt for a baby, you can use common things that are attractive to babies such as toys, animals, alphabets etc. Also since it's a baby, choose the color wisely. Don't choose dark colors, but go for soft baby colors such as light pink, light blue, light yellow etc.

Technology Gives A Cutting Edge in Cutting Sheet and Plate Metals

Technological advances in the field of manufacturing are what companies use to gain and maintain a Cutting Edge over their competition. Thirty years ago no one would believe the technologies of James Bond and Star Wars would find their way to the metal fabricator's shop floor; but they have. Two innovative alternatives to burning or oxidizing sheet and plate steel are:

* Laser Cutting of steel
* Plasma Cutting of steel

Laser Technology gained much ground in the 1980's through Defense Department research. The Strategic Defense Initiative (SDI) paved the way for today's advanced commercial applications of laser use.

Laser is a word derived from Light Amplification by Stimulated Emission of Radiation. It involves the use of an electronic optical device. In the case of steel, output from the device, the laser beam, targets an area of the sheet or plate. This laser stream receives its direction from a computer, which pinpoints the area requiring the cut.

Cutting steel with a laser-cutting machine offers an accurate clean cut. Many other materials benefit from this process, such as wood, copper and exotic alloys. Sheet and plate steel receive cuts of close tolerance, much faster than traditional cutting methods. Laser cutting machines are capable of cutting steel up to one inch thick. These machines can perform these accurate cuts repeatedly and with high consistency.

With laser cutting, the cut edges of the steel are clean. This leaves a cut edge with a nice surface finish. This type of cutting allows for less warping of steel; as the zone affected by the heat is small. Laser applications mean less physical contact with the sheet or plate steel. This means less wear on the steel being cut and less chance of a poor quality cut.

Another great advantage of laser cutting of steel is that there is no wear on the laser. This is an advantage over mechanical cutting tools, which undergo stress and wear in the cutting process. If proper maintenance is performed on the optical mirrors used to reflect the laser beam to its target, many months of use are possible before they must be replaced; unlike standard tooling.

Plasma cutting machines utilize a different process. A plasma cutter or torch uses inert gas or compressed air. It uses pressurized nitrogen, argon, or oxygen. Today the use of compressed air is more common.

This air propels at high speed from the cutter nozzle. As air rushes through this specially designed nozzle, an electrical arc develops. This air hits the surface of the steel sheet or plate. Some of this air (or gas) turns to plasma: plasma that is very hot and able to melt the steel receiving the cut. Because it moves at high speed, the plasma blows away the molten metal. This blowing away of molten metal is the cutting process in action.

Plasma cutting machines can cut steel of one inch or less. The plasma cutting process can make non-linear or curved and angled cuts. It works faster on thinner steel than the burning or oxy-fuel process. Any conductive material (ability to transmit electricity) can have the plasma cutting method applied.

The introduction of smaller nozzles and thinner plasma electrical arcs are the result of advances in plasma Technology . These produce cut edges close to the quality of those produced by laser methods.

The use of laser and plasma cutting machines give manufacturers the ability to make cuts that are more precise. It also gives them the capability of making different types of cuts, all with greater speed. This helps the efficiency of their operations in the competitive business climate of today.

The steel industry continues to be on the Cutting Edge of steel Technology " title="cutting Technology ">cutting Technology. And lasers and plasma cutters are one of the methods they employ to stay there.

Laser Cutting Machines and Their Attributes

Laser Cutting Machines and Their Attributes

Laser cutting machines allow metal fabricators to create high-quality parts that require very little, if any, finishing work. As the high-powered laser is cutting, excess material is either melts, burns or vaporizes away. A high pressure jet of gas also blows away any debris, resulting in a highly finished surface cut.

Two types of laser cutting machines in use today are CO2 and Nd:YAG. CO2 laser cutting machines were one of the first gas lasers and are the most common variety of laser cutting machine. They offer an excellent power input output ratio, as efficient as 20 percent. Nd:YAG lasers are solid state and use a crystal as a lasing medium. They cut steel and other alloys in the metal working industry.

Laser Cutting vs. Mechanical Cutting

Laser cutting machines are distinct from traditional mechanical cutters. Since the laser never makes physical contact with the metal, there is little to no wear on the equipment, and there is less opportunity for the material to become contaminated. Laser cutting machines also cut metal with higher precision than that of mechanical means.

In mechanical cutting, there is usually a wide heat affected zone that can cause material warping from time to time. Thanks to laser cutting machines, the heat affected zone is kept small, thus reducing the possibility of warped material. Although laser cutting offers numerous advantages, it also consumes a very high level of energy, making it more difficult for a conventional machine shop to incorporate into its metal fabrication system.

Benefits of Laser Cutting Machines

Laser cutting machines offer a substantial number of benefits for consideration when selecting a cutting device. Besides its advantages over conventional mechanical cutting, laser cutting is a quiet process. Safety is also important and, as a result, most laser machines are fully enclosed to prevent accidents.

Lasers are equipped with computer touch screens, so workers can plot out design alterations for prototypes and large part runs. The lasers progress quickly because of high feed rates and equipment speed. Workers can also cut multiple jobs in one run by storing inventory on site.

Laser Cutting Machine Considerations

While exceptional for cutting steel and other hard metals, laser cutting machines typically do not function well on highly reflective metals, like copper and aluminum. Since these metals easily reflect the laser's light and also absorb its heat, highly-powered beams are required to cut them.

When piercing, laser cutting machines create slightly tapered holes. due to the hole entry being slightly larger in diameter than the exit.

Since laser cutting melts the material in the beam’s path, metal can harden in the puncture, especially in heat treated material. While this may be beneficial for some applications, this issue can be detrimental to those requiring further work, like threading.

more cutting machine information


In every machining system, one simply can't ignore the important role that Cutting Tools play. Oftentimes, the quality of a finished product would rely on the quality of the Cutting Tools . The quality and the performance of Cutting Tools would also directly affect a machining system's overall productivity. It is because of their importance that manufacturers would take into consideration several criteria before eventually buying a piece of cutting tool for their machining system. Included in these criteria are the tools ability to last long under rigorous operating conditions and their capability to perform at very high speeds. Also important is the tool's resistance to wear and tear, including resistance to breakage, edge and flank wear, cratering or top wear, chipping, built-up edge (BUE), deformation, and thermal cracking.

1. Kinds Of Tools

As the demand for better Cutting Tools increase, cutting tool suppliers also continuously develop products that can pass manufacturers' demands. Through the years, a lot of materials for the manufacture of Cutting Tools have been experimented upon; some have passed the standards while others were simply dropped. Today, there are only two types of Cutting Tools heavily favored in the machining industry: high speed steel (HSS) Cutting Tools and carbide Cutting Tools ; and it seems that carbide Cutting Tools have slightly overtaken the other in popularity. So, what advantages do carbide Cutting Tools have over their HSS counterparts? Considering their lead in popularity, it is clear that the benefits of carbide Cutting Tools outnumber that of HSS Cutting Tools . And we'll understand these benefits better if we know what carbide really is.

2. What is Carbide?

In chemistry, carbides refer to any group of compounds made up of carbon and one other element that can be a metal, boron, or silicon. There are actually many compounds belonging to this group, among the more popular of which includes:

- Calcium Carbide - Aluminum Carbide - Silicon Carbide - Tungsten Carbide - Iron Carbide

3. Industrial Uses of Carbide

In the 20th century, carbides have been used for a lot of industrial applications. Carbides used in industrial applications are often called cemented carbide products and are classified in three major grades:

- Wear grades Used primarily in dies, machine and tool guides

- Impact grades Higher shock resistance carbide products used for dies, particularly for stamping and forming

- Cutting tool grades Carbide tools used for cutting

4. Carbide Cutting Tools

Cutting tool grades of carbides are further subdivided into two groups: cast-iron carbides and steel-grade carbides. As their name implies, cast-iron carbides are specifically made for cutting cast-iron materials. These carbides are more resistant to abrasive wear, protecting the carbide cutting tool from edge wear due to the high abrasiveness of cast-iron. Steel-grade carbides, on the other hand, are specially made to resist cratering and heat deformation that may be caused by the long chips of steel on higher cutting speeds. Whichever grade of carbide is used in a carbide cutting tool, the main carbide material used in its manufacture is tungsten carbide (WC) with a cobalt binder. Tungsten carbide is well known for its hardness and resistance to abrasive wear. Cobalt, on the other hand, is used to further toughen the tool's surface.

5. Other Variants

Aside from tungsten carbide and cobalt, other alloying materials are added in the manufacture of carbide Cutting Tools . Among them is titanium carbide and tantalum carbide. Titanium carbide helps the carbide cutting tool to resist cratering while tantalum carbide can reduce heat deformations in the tool. Also commonly used in the cutting industry today are coated carbide Cutting Tools . Aside from the basic carbide materials, titanium carbide, titanium nitride, ceramic coating, diamond coating or titanium carbonitride are used as coating materials. The different coating materials aid the carbide cutting tool differently, although they are generally used to further toughen the cutting tool.

6. Benefits of Carbide Cutting Tools

- Toughness - Exceptional resistance to abrasion - Superior wear resistance - Resistance to cratering - Resistance to thermal deformations

- High modulus of elasticity - Chemical inertness - Torsional strength twice that of HSS - Compressive strength

The only thing that interferes with my learning is my education

The way in which education (in our case "higher education") ought to be, is a diverse and complicated subject, for inquiry or claim. It is a multifaceted and super-conceived edification of transcendence. Being as such, there is no possible way for me to convey a fully developed concept within this cage of the Globe's pages, without undermining my attempts, and I would no doubt neglect something significant, although it probably is so regardless. But, nevertheless, in this poeticized piece, I will be critiquing current educational practices as they far too often appear to hold in the co-defining conceptions erected of the student-teacher-administrative creative projections, from a very narrow standpoint. Moreover, although I will be making a proposition in the face of academic addictions, not all is of my own original convictions, though I may subscribe, in these cases, I am just a messenger of wisdoms. It is not so much important, nor quite my intention, that I change people's impressions on what ought to be expected of quality education, or what is wrong with our current model, as much as it is that people, at least to start off with, truly feel and earnestly think critically about what education means and what it ought to proliferate in one's life on a micro, macro, and meta scaling.

The issue I will cover is whether many of the American values, narratives, norms, and collective identities' influences are subliminally, if not forthrightly, self-refuting and ultimately degrading to the experience and growth of students, not only in the context of institutional educational practices but also in erudition in-itself. The main areas of concern that this essay will be covering are: first, most schools are run for profit at the expense of education; second, intellectual laziness is disseminated in education through a teachers-students disparity; third, there is a false dualism between the discrimination of importance of career oriented schooling and humanities education; and finally, the ideal of education.

Education is marketed as a product, imbuing commoditized values of success and independence, as a package deal to buy into a job, one with benefits and a blindfold. Net profit and distributed royalties rise with sweatshop pedagogy. While the bottom line is considered the beginning of decision-making in a school of learning, edification will always be replaced with indoctrination. Surrogate teachers and shadow supplies at the bargain price of a stagnant development. People are obscured as resources or faceless consumers, to be tended to to the extent that they can consume or reinvest. The domination of the administration, as a figurehead to the self-consuming social value, and the entitlement they arbitrarily demand, is coercively corrosive in the way of governance toward teacher's practices. Lessons are now administered through an I.V and the instructor is just a panoptic enforcer of approved budget curriculum. Subsequently, through the noise of everything unsaid but expected and the ruse of a business as a school, students are molded into submissive soldiers that guard the ideology that spawned them, perpetuating their own oppression and striving to be promoted to oppressor.

The propaganda that is created in this ideology embodied within the teacher-student relation is the value of indifference to the essence of enlightenment, promoting intellectual laziness as a prerequisite to a misguided meaning of our endeavors. Do we not desire meaning and liveliness expressed, discourse without domination, instead of estranged relationships in our heads? Alas, meaningfulness is a luxury we pay for on our deathbeds, and immediate gratification is best spoon fed on a full belly of lethargy. Our apathy is exaggerated by the powerlessness to engage the absurd and is mirrored by the functional application of our educationalist's desire to escape from the same absurdity of life that enslaves us. We are a teacher-student relationship interdependently co-narrating each other's search for meaning, not independent objects on a hierarchical scale of entitlement. As long as a disparity of the teacher-student false dichotomy exists, creative understanding will be dismissed. Teachers are seen to transfer their pretentious information onto the tabula rasa of the student's docile receptacles, banking dead dogmas, while mechanically validating both of their existences with movement, as if it was creative intelligence. What is transferred is a stagnant evanescence of information without any substance or significance associated with it, and even if it is given definition, the associations are still alien to one another. Performance is based not on the creativity or analysis but on how well one is able to fill the machine, and on the machines part, how submissively it lets itself be filled. The teacher acts and the students have the illusion of acting through the action of the teacher. The teacher is the subject of the learning process while the pupils are mere objects. Students conform to this method and simultaneously reinforcing the teacher's repression. We are not in school for learning but for proper etiquette within a disciplines culture's mores. Intellectual laziness could ask for no better passengers than docile bodies. Moreover, we as students do nothing to renounce hegemony but more so encourage it for the easy attainment of a passing grade and its implications, and not that of edification for-itself.

Most students only see school as training for a job, but teachers seldom discourage this thought. If asked what you're going to school for, would you not posit a response in the shadow of a career to be bought into indentured-slavery? Too often, becoming a contributing member of the economy is the beginning point of a student's educational decisions. Moreover, the humanities education is written off as a pass time to masturbate to on your days off. Consciousness is the curse of condemned freedom, and endowed are we with the responsibility to the absolute or the absurd, demanding of the gods, dignity be preserved. We need to act as active agents engaged within our realities, and not just passive observers washing over the scenery. The ideal goals of both disciplines are not entirely estranged, but another false dichotomy supporting cultural values misplaced. We're all talk and no action or all action and no talk. To neglect one is to accept none.

We mechanically hum along to the noise of formalities in bad faith, while we long for escape from a self-fulfilling prophecy of oppression veiled in crass success and allusions of marginalized kindness, nevertheless measured by the degradation of others' regrets of self-respect and how green the grass is on the graves we step. This is coercive self-expression of a monotonous split personality's obsessions. Our false double consciousness, through the cross eyes of a dimly enlightened desire for meaningfulness we bought for half price, is the catalyst of our lazy economic domination of fear and our political nausea. Like the snake eating its own tail, we are the mundane product of a perpetuated estrangement of ourselves, as a means to a misguided end, compartmentalizing our exuberance while drilling a void in our heads. The oppressors of the world throughout history have never willingly given up control it has to be demanded. What makes you think that this is any different? What ought to be the point of education behind the veil of ignorance?
