The Process of Getting Started With Your Archery Bow

If you are thinking about getting involved in archery, but you are not sure what you need, then you are in luck. One thing that I like about this sport is that there are only a few things that you need to get off and running. Obviously, the first thing that you would need to buy is one of the many archery bows that are on the market today. Next, you will need to get arrows to shoot. To make your life a bit easier, there are also some accessories that I would recommend.


When you first start you will need to make the decision on which of the many archery bows you would like to shoot. There are compounds, recurves, takedown bows, longbows, etc. out there so it is best that you do a bit of research on them before you commit buying your bow of choice. They all have their own unique set of attributes that are made to fit archers of all varieties. Once you figure out what type of shooting you want to do, then you need to figure out how much you are willing to spend. This will help you narrow down your focus and hone in on a decision.


You now need to get yourself something to shoot. The most popular arrows that you will find out there are wood, aluminum and carbon. I have personally transitioned from using the wood arrows in my childhood, to aluminum in my teens, and now the only thing that I use is carbon. Everything matters when you are shooting your archery bow, so you need to make sure that the arrows are consistent. Carbon is extremely consistent, but they will be the most expensive. Aluminum is a good starter arrow because they are relatively inexpensive, and are more consistent than wood. I would suggest staying away from wood arrows until you have developed an eye for purchasing arrows because it is much harder to find a quality wood version.


I would also suggest that you get an archery arm glove or an archery bow release-depending on the type of bow that you purchased. When I began shooting, I mainly liked to use recurve bows. When you start to move up in weight, your fingers get sore after 40-50 shots due to finger pinch — unless you are using a glove. Once I moved up to a compound bow, I knew that there would be no way that I would be able to draw a 55-70 pound compound bow with my fingers so I opted to use an archery bow release.


If you are anything like me, then you will probably also want to get an archery target so that you do not have to drive to your local archery range every time that you want to shoot. I purchased a Bulldog archery target as they offer a lifetime guarantee. This means that I can shoot off a couple of dozen arrows when I feel that I need a little bit extra practice. Again, the archery target is not a necessity like the arrows, and the archery bows are, but having one never hurts so that you can get as much practice as possible out of it.


Once you have your bow, arrows, target and accessories you can start the fun part. Shooting an archery bow is the next journey that you will embark on. Getting the equipment was the easiest part, now it is time to perfect your form. It is good to read up on tips and tricks when shooting your archery bow, but shooting is the best.

The Basics of High Speed EDM Hole Drilling

This article discusses how EDM hold drilling – designed for fast, accurate small- and deep-hole drilling applications – has become a whole new method of manufacturing molds and parts.


High speed EDM hole drilling was designed especially for fast, accurate small- and deep-hole drilling applications. Small holes that were once almost impossible to drill by conventional machine tools are now being performed with ease. With the capability of drilling through virtually any conductive material, the use of this technology is continually expanding.


Initially shops were using this technology specifically for start holes in wire EDM jobs. Because of this technology, workpiece materials are being sent out for heat treating prior to drilling the start hole. This removed two problems: (1) having to program, locate and drill the start hole by conventional machine methods in the “soft” workpiece prior to heat treat and (2) by sending the workpiece for heat treat before drilling the start hole, all the stresses were being removed from the workpiece prior to the EDM process being applied. As this process became more widely known, test burns were being done in more than just hardened tool steel; tungsten carbide, aluminum, brass and inconel were being tested. High-speed EDM hole drilling applications began to expand to mold and part manufacturing-injection nozzles, oil drain holes, hydraulic cylinders and dowel pins, as well as turbine blades, ball bearings and safety wire holes in hex nuts, to name a few.


Basic Features of the EDM Hole Driller Machine

  • Stainless steel work table
  • Rotating spindle
  • Drill chuck or collet system for holding electrodes
  • Ceramic or diamond guides
  • Power supply with control panel
  • Capacitor box
  • Dielectric fluid pump


The EDM Drilling Process

The process consists of using a precision tubular electrode (generally brass or copper) mounted into the drill chuck located on the “Z” axis and held in location on top of the workpiece by the ceramic guide. The top of the workpiece is located and the drilling depth is set. The electrode rotation is turned on and the deionized water solution, which is pressurized between 50 and 100 kg/cm2, is sent through the tubular electrode as a flushing agent. The power supply parameters are set-which normally consist of on-time, off-time, peak current and amount of capacitance. At this point, the discharge is turned on to begin the drilling cycle. At the end of the drilling cycle, the discharge is turned off and the “Z” axis is retracted above the workpiece.


Drilling Times

Drilling times are based on the hole size and type of material. Chart I lists a few samples for reference.


Chart I

Material Electrode Dia. Drill Depth Machining Time
Alloy Tool Steel .020″ 0.50″ 25 to 35 seconds
1.00″ 50 to 60 seconds
.040″ 1.00″ 55 to 65 seconds
Tungsten Carbide .020″ 0.50″ 4 to 5 minutes
1.00″ 8 to 9 minutes
Aluminum .020″ 0.50″ 40 to 50 seconds
1.00″ 90 to 100 seconds
.040″ 2.75″ 3 minutes


Observing the aforementioned times explains why high-speed EDM hole drilling has become an alternate method to conventional machining in mold manufacturing. In addition, this method of drilling produces burr-free holes, which results in the elimination of secondary deburring processes. Larger power supplies and drill/collet chucks have expanded the diameter range of standard drilled hole sizes from .010″ to .118″ to .010″ to .236″. EDM hole drilling can now be done on a manual, ZNC or CNC machine.


Today, many of the machines use distilled water as the flushing agent, which opens up new application possibilities in the medical field. With continued improvement in this technology, more and more applications are being seen on the horizon – EDM hole drilling has become a whole new method of manufacturing molds and parts.

What Are CNC Rotary Tables And How Are They Used?

CNC rotary tables are a key to automated machining. Before getting into the specifics of CNC rotary tables though, a brief discourse in the development and terminology of CNC machining will help from this point forward.


CNC is an acronym for Computer Numerical Control. It is the direct descendant of numerical control (NC) technology; think punch cards and magnetic tape. In turn, NC technology was invented to improve upon cam and tracer machine control in use at that time. Cam and tracer machining required construction of a template to trace and that interposed a costly, time-consuming step that had significant potential for human error.


Rotary Tables Defined


A rotary table is, as its name suggests, a table that rotates very accurately in concentric fashion around its center axis. In the high-accuracy, high-cost category of rotary tables, accuracy can mean radial runout – the amount of deviation from perfectly centered while rotating on the center axis – of 0.00004 of an inch and angular accuracy – degrees of rotation about the center axis – of 0.0002 of an inch. For the purpose of dampening vibration, the body of a rotary table is normally made of one of the “gray” iron grades. The rotating table plate is typically hardened, alloyed steel that is machined and rotary ground.


Purpose of CNC Rotary Tables


For automated machining, the entire purpose of CNC rotary tables is to provide a fourth axis. In addition to the normal axes of X, Y and Z, a CNC rotary table adds a rotational axis, known as the “W” axis, to increase machine accuracy and reduce costs. For example, using a CNC milling machine alone to make a stop sign-shaped piece would require moving the cutting tool around the piece to cut the vertical and horizontal sides and then cutting the angled sides by moving the cutting tool on a 45 degree angle as it is removing material. This requires eight machining passes. Each operation introduces a cumulative dimensional error for the sides parallel each other. Using a CNC rotary table for the same part means positioning the cutter in X or Y one time while rotating the part in 45 degree increments for each horizontal or vertical pass. Because it is cutting on only one side of the cutter in either X or Y, any machine tolerance error, tool wear and normal tool deflection from the forces of machining are reduce by half.

An Exciting Array of Water Dispensers to Choose From

Modern living has become highly sophisticated and a lot of pressing concerns can cause elevated stress and physical breakdown. Good thing water dispensers came into the consumer world to help alleviate the high demands on time and energy.


A wide array of under sink water chiller and hot water dispenser brands is available and each comes with a price tag that suits every budget. Exciting designs and features will surely dazzle even the most meticulous customer.


The following sections discuss two types of water dispensing machines that are great value for money. The first one is able to provide sparklingly chilled water as really delightful refreshment. The second one produces boiling hot water needed to make coffee, tea and other hot drinks.


Under Sink Water Chillers


These water dispensing machines eliminate the cost and hassle of spending precious time going to the supermarket whenever bottled water has run out. They are equipped with a technologically advanced in line filtration system that can adequately provide a consistent source of chilled and filtered water. The water tastes absolutely great and it does not have the odors oftentimes associated with a mains water supply.


The under sink or under counter water chillers are cost effective as well as environmentally friendly. They are directly connected to the mains water supply and the water passes through the in line filtration system. Organic chemicals and undesirable tastes and odors are effectively removed. The filtration process then yields crystal clear and fresh tasting water that is dispensed via the available tap of the machine.


There are other essential features that every consumer must watch out for. It is best that the dispensers are built of stainless steel for durability while the coating is ideally of scratch and impact resistant plastic.


The refrigeration system must be efficient and silent if possible. With a static condenser, the operation will be incredibly great, providing considerable energy savings.


The sealed ice bank of the cooling system must be ensured at all times. Doing so will retain the hygienic levels of the dispensed water. There will then be a continual supply of ice cold water that is free from bacteria obtained from external sources. Also, the need for regular sanitization is reduced.


The maintenance of the units is very easy and economical for the filter change and sanitization are done once every 6 months. The product supplier has replacement filters and sanitization kits readily available to prevent any hitch in the use of the machine.


The most important thing to consider is that the dispensers bear the CE mark to ascertain that they have passed the European standards for product safety and usability.


Hot Water Dispensers


These appliances dispense water at near boiling point or at about 94 degrees Centigrade. They are commonly known as boiling water taps. They are available in two models such as hot only, and hot and cold water types. They are kettle like product items that boil and dispense single mugful of water.


They normally have variable settings in the quantity of water being dispensed. A few seconds is all it takes to dispense water via the hot water dispensers. This means potential energy saving benefits can be acquired because only the necessary amount of water is boiled.


The other types of hot water dispensing machines include boil on demand heaters, tank dispensers and thermo pot water dispensers. The boil on demand types of heaters is small, portable and cheap. It does not need installation and is an energy saver.


The hot water tank type of dispensers needs to be plumbed directly to the water supply. The water is then heated and dispensed via the faucet. It has a built in filter and thermostat.


The thermo pot type of hot water dispensers combines the features of an electric kettle and a hot water flask. It is potable and requires no installation.


Water dispensers have innovative designs and awesome features to choose from. Remarkably, they possess both beauty and functionally that make modern life less stressful.


There is a choice between countertop and under sink water chiller models, depending on individual preferences. Also, various hot water dispenser brands are also being offered and they serve as great alternatives for the traditional way of boiling water using a kettle.

The Advantages and Disadvantages of Embroidery Patches

If you’re thinking about purchasing an embroidery patch that is custom made to suit your needs, you must first know what the most ideal backing material for your design. You also need to know the quality of the garment and the length of time the patch backings will last.


Depending on the process, here are the three types of patch backing.


  1. Iron-On Backing with Heat Sealing.
  2. Velcro Backing with Hooks and Loops.
  3. Adhesive Backing with Stick-On or special adhesive.


Before make a decision, write down the advantages and disadvantages associated with each of them.


Iron-On Backing


When you use iron-on backing on your patch, you will only receive a temporary security, because it won’t last long. This backing is ideal for ceremonial and casual clothing, but never uses it for any kind of exercises or training. They are mostly used to securely place the patch during the sewing process, so iron-on backing is not the best choice if you want to use it for your active lifestyle purposes.


Advantages and Disadvantages:


  • Ideal for ceremonial purposes.
  • Avoid heavily worn.
  • Avoid frequent cleaning.


Velcro Backing


Velcro backing has two styles of the backing material. Hook-sided for males and Two-sided for both males and females. Hook-sided is the best choice when you need to change new patches frequently or other small adjustments like in the case of military and police uniforms. But if a loop fastener isn’t attached on the clothing, we can use two-sided Velcro backing in the process.


As in Iron-on, Velcro backing also has advantages and disadvantages:


  • More durable. You can remove the patches before cleaning so they last longer.
  • Greater Flexibility. The patches can be easily removed and reattached anytime.
  • The only disadvantage is because Velcro patches are attached loosely.


Adhesive Backing


The most popular and familiar kind of backing used for embroidery patches is adhesive backing. It’s very convenient and the backing process is very easy. Today, this is the most ideal choice for short-term events. Adhesive backing is the best choice for one-time event, but it has its own disadvantage if you want to use for a long time.


The advantages and disadvantages of adhesive backing are below:


  • Easy to use on any garment.
  • Ideal patch backing for a short time span.
  • Stay away when the patchwork is required to remain permanent.


Patch Attach is a special kind of glue that can offer an extra way to add patches onto clothing and garments. The glue joins any kind of fabric you may think of and there will be no need to sew. It is washable, non-toxic and can be removed easily when subjected to heat. Most important is this glue will keep your patches permanent.


But among all of the methods above, the most ideal of attaching patches is by sewing them onto a garment. When sewn, the patch remains attached on the cloth for a long period of time. Experts claim that it can even last for decades.


Having made a decision on the kind of backing you need, it is now the time to look for an expert to do all the necessary steps in designing the patches.

Accumulators and Their Capacity

Piston accumulator is a kind of the fluid power component, and is the only one which can store the energy in hydraulic systems. The unique advantage of piston accumulators is energy storage in usually and used in emergency, it also has several functions, such as temperature compensation, leakage compensation, counter balance, shock absorption, transfer barrier, shock dampening and pulsation dampening.


Today even modern accumulators possess limited capacity although their parameters develop every day. Alkaline accumulators are most popular accumulators as power suppliers for portable devices. For the past 25 years the capacity of accumulators has increased 5 times (just compare: properties of electronic devices have improved in thousand times). Thus, the accumulator capacity is ultimate and limited by sizes of its case. New advanced technologies don’t increase the capacity considerably, moreover, newest scientific data does not expect significant increases in capacity among this energy sources in the nearest future.


Unfortunately, as long as accumulators are based on electrochemical processes, we will be limited by energy storage devices. We will have to use accumulators big in their sizes, heavy, flaky, unpredictable in operation, rather expensive and thus, with a rather short term of life. Moreover, attempts of increase in capacity, reduction of weight and sizes of accumulators have led to by-effects, such as: a shorter service life and an increased self-category, without mentioning higher working costs. The matter is that one of methods to increase the capacity of accumulators is the use of a thinner plate of a separator dividing the anode and the cathode and which collapses faster, a consequence of that is the increased self-discharge. It means that buying an accumulator with a maximum capacity, we obviously get an energy source designed for the minimum durability. Probably, some of you have ever noticed that many accumulators which were produced in the 80’s, 70’s and even in the 60’s are still in use, while those bought in the 90’s are already out of order.


Today developments of fuel elements (hydrogen, spirit, gas, etc.) are considered as the most perspective but they are still far from perfect and are inaccessible to ordinary consumers. Along with the improvement of energy products, modernization of power consumers takes place. Much less energy is consumed by modern electronic devices than by their predecessors. All these circumstances allow using advanced achievements of science and engineering in the field of electro-power supply for achievement of more essential results.


Ashun piston accumulators have three standard types, A280, B250 and C210, which are all certified by the EU Pressure Equipment Directive 2014/68/EU (MODULE H1) with quality assurance. Their accumulators can be widely used in hydraulic power units of various types of machine tools, we also serve customization, welcome to contact with Ashun Fluid Power Co., Ltd.!

Which Material is Right for Batting Cage Nets?

Urethane treated nylon, polyethylene, polyester, and KVX200™ are common material used in batting cage nets. However, KVX200™ premium netting is a commercial polymer that is also used in bullet proof vests. This material is strong, lightweight, does not absorb water, and resists breakdown in direct sunlight. KVX200™ employs an integral UV inhibitor. This means that the UV inhibitor is one component that is already inside the polymeric blend that gets extruded into individual fibers. Those fibers are then twisted or braided into twine. Since the UV inhibitor is built right into KVX200™, the UV inhibitor doesn’t wear off, as it can with nylon. Since KVX200™ doesn’t absorb water as nylon can, it resists rotting better than nylon or other materials.




KVX200™ is more expensive than polyethylene, although it is less expensive than nylon. While KVX200™ may be stronger than polyethylene, it doesn’t have the break strength of Nylon. KVX200™ is priced between nylon and polyethylene netting. For outdoor use the performance is nearly on par with nylon. These cages may provide the best value for those concerned with both quality and price.




If you have an indoor cage, and durability and break strength is more important than budget, nylon netting is right for you. Nylon has the strongest break strength, and is by far the most durable netting for indoor use. Nylon has excellent resistance to abrasion, and outstanding overall durability. However, nylon is expensive.


Because nylon netting can absorb water, many manufacturers treat the nylon with some sort of bonding agent by either dipping or spraying the twine. Although treating nylon with a bonding agent will dramatically reduce nylon’s tendency to soak up water, it doesn’t stop it entirely. Eventually, nylon will likely shrink and rot.


When compared with polyethylene netting, nylon is initially stronger than polyethylene, but deteriorates faster. Nylon loses between 15% and 20% of its strength each year depending on conditions. For year one, a #36 nylon will have a greater break strength than a #36 polyethylene, but depending upon weather conditions, by the end of the third year polyethylene may be as strong, and KVX200™ may be stronger.


Although nylon netting has a high initial break strength, if left outside that strength can deteriorate rapidly. Nylon absorbs water and loses strength in direct sunlight. For indoor applications, nylon is an excellent choice. If your netting will be exposed to adverse weather, consider polyethylene or KVX200™.




Polyethylene batting cage net is inexpensive and does not deteriorate as quickly due to moisture. As the netting is exposed to moisture, polyethylene retains a higher percentage of its strength than nylon. Polyethylene does not absorb water, so the problem of rotting and shrinkage disappears.


Polyethylene netting has drawbacks as well. Most blends of polyethylene don’t hold up well to direct sunlight. Not all polyethylene cages incorporate UV inhibitors. Ours do. This works well for indoor application, but it may not be practical over extended periods of outdoor use, especially in warmer climates.
