Dart Flights

Flights are the fins or wings found at the back of a dart. It is used to stabilize your dart in the air. Flights are available in a vast selection of colors, sizes and materials. There is no "correct" or "best" flight shape. It depends on your personal throw which flight to choose. Selecting the proper flight for your darts is a trial-error process. 

Soft flights are made of a flexible plastic sheet, preprinted with a variety of designs and then folded into shape. Adhesive (glue) holds the layers of plastic together. A benefit of this type of flight is that a soft flight will often flex out of the way if another dart hits it. These flights are available in hundreds of bright, attractive designs. Also known as "Reseal Flights".

Hard flights are made of stiff polyester plastic that holds shape well. The layers are permanently sealed together by heat during production. Hard Flights do not flex like soft flight when hitting, but do "pop off" the shaft when hitting another dart. This is desirable as it reduces deflection and allows tight groups. Hard Flights were originally made of a clear plastic, which resulted in fairly dull colors in printed designs.

Nylon flights are the most durable type of flights. These dart flights are very hard to tear. The stiffness varies according to the weight and type of fabric used by the manufacturer, but is roughly midway between soft and hard flights. Since rips top nylon fabric is a thicker material, it is important to pry open the slots on the shaft for a properly loose fit to avoid damage to the flight. Nylon Flights are available in solid colors and dozens of printed designs.

Getting Tungsten Disulfide to Stick

Tungsten disulfide is commonly known by its chemical formula, WS2. Tungsten disulfide can be used as a dry lubricant for mechanical parts, and is often preferred because it can be used within a wide range of temperatures and will not introduce contaminants into the machinery. Sandblasting equipment can be used to apply the lubricant. Otherwise, WS2 can be applied with a buffing wheel. If the WS2 can be mixed with wet lubricants in your application, it may be added to oil or other lubricants. If you are applying WS2 to small parts, a tumbler may be used.

Instructions

Buffing
1
Clean the part with a rag to get all of the grease off.

2
Mix the tungsten disulfide powder with rubbing alcohol in a small glass jar. Start by pouring in just a small amount of alcohol and mixing thoroughly with a spoon. Keep pouring more alcohol until you have a grey paste.

3
Spread the paste onto the part and the buffing wheel. Allow them some time to dry thoroughly.

4
Turn on the wheel and press the part up against it, turning the part and buffing it until the part is coated a grey color.

Tumbling
5
Clean the part with a rag to get all of the grease off.

6
Put several of your small parts or bullets into the empty aspirin bottle.

7
Fill the bottle three-quarters of the way up with tungsten disulfide.

8
Place the bottle in the tumbler. Turn the tumbler on for approximately five hours.

Add Tungsten Disulfide to Lubrication
9
Clean the part with a rag to get all of the grease off.

10
Mix some tungsten disulfide in with fresh lubrication, oil or grease.

11
Grease the part, change the oil oar and apply the new lubrication. The tungsten disulfide will slowly coat the parts as the lubrication moves through the machinery.

Sand Blasting
12
Clean the part with a rag to get all of the grease off.

13
Blast the part with a light layer of aluminum oxide.

14
Clean the part off with a clean soft cloth so there is no trace of aluminum oxide powder.

15
Set the sand blaster to 120 PSI and to cold pneumatic air. Blast the tungsten disulfide onto the part until the part becomes a silver-grey color.

16
Clean the excess tungsten disulfide dust off with another clean cloth. Do not rub too hard or you will remove the powder.

Could Tungsten Rings Be Resized?

Tungsten is an extremely durable metal that makes a great alternative for a mens ring. It cannot be scratched, bent or wore down making it a sought after option for a wedding band. However, one of the drawbacks to the tungsten ring is that it cannot be sized once the ring is made. Caring and correct sizing will ensure you order the correct finger size.

What is Tungsten
Tungsten is a very hard, brittle, grey to white metal that is extremely corrosion resistant. The major sources of this metallic chemical element are in Russia, Austria, China and Portugal. It is extracted from minerals like scheelite and wolframite. It cannot be found in a pure from in nature. It is about ten times harder than 18k gold and five times harder than steel.

Resizing Tungsten
Because tungsten is extremely durable and hard, it is impossible to resize. You will need to get your finger sized correctly and order the ring in that size. Most jewelry retailers include or offer a lifetime warranty on tungsten rings that includes free ordering of new sizes if your finger changes in size.

Benefits
Tungsten is so durable that it won't wear down, bend or scratch. It has a high resistance tarnish and holds a shine once it is polished. It is also hypoallergenic. Due to its durability and scratch resistance, tungsten is a great alternative for men who work heavily with their hands.

Considerations
Tungsten is heavy and the weight of it may feel heavy on your finger. It cannot be resized if you needed a new size in the future. You will need to order a whole new ring if you need a different size. Tungsten cannot be engraved like gold or silver but can be laser etched for an additional price. In the case of an emergency, tungsten cannot be cut off your finger.

Cleaning and Care
Tungsten rings will need to be polished with cloth if smudges and fingerprints incur. It does not scratch but may look like if it is accidentally rubbed up against something else. If this happens, use a soft tooth brush and liquid soap to brush away the rubbings on the ring.

About Tungsten Jewelry

Tungsten jewelry has gained popularity due to both the modern look that the metal provides and its ability to resist scratching and bending.

Characteristics
Tungsten, also known as wolfram, is a gray transition metal that is mined in Europe, North America, South America and Asia. Along with its use in jewelry, the element is also used in electric lamps, X-rays and in the development of spacecraft.

Jewelry
In its raw state, tungsten is a very brittle metal that can be easily cut with a hacksaw. In order to create jewelry such as a ring or bracelet from tungsten, it must be strengthened. This is achieved by combining tungsten powder with carbon and another metal such as nickel or cobalt.

Use
Due to the weight of tungsten jewelry, it is not typically used in earrings and pendants. It is more common to find tungsten carbide in rings, bracelets and watches. Jewelry made from tungsten will resist scratching, bending and stretching better than gold or silver.

Appearance
Tungsten carbide jewelry features a darker hue that can be polished to resemble hematite. When mixed with nickel, the resulting appearance is similar to that of platinum.

Care
Due to the metal's ability to maintain shape and shine over time, very little care is required for tungsten jewelry. Retailers of tungsten carbide jewelry caution against cleaning with chemicals or with ultrasonic cleaners, suggesting soap and water instead.

How to Determine If Tungsten Carbide Contains Cobalt

Tungsten carbide is a common term used when discussing jewelry. However, tungsten carbide is used in a wide range of manufacturing processes. In many cases, tungsten carbide contains cobalt. Cobalt contains nickel and chromium. These chemicals can increases the chances of severe asthma and "hard metal lung" disease.
The average employee working with tungsten carbide does not have access to the testing equipment necessary to test for cobalt. However, thanks to government regulations, there is one way you can determine of the tungsten carbide you work with has cobalt in it.

Instructions

1
Locate the packaging for all tools that use hardened metal tips such as end-mills, drill bits, cutters and saw blades.

2
Read the labels on the packaging. If the packaging indicates the tips of these tools are hardened carbide, they have cobalt mixed in with the alloy. As you use these tools, they wear down and create dust contaminated with cobalt.

3
Locate the packaging for any tungsten carbide raw materials. All raw materials have a "material safety data sheet." The MSDS must indicate all of the ingredients used in the manufacturer of the raw materials. If the carbide has cobalt in it, it is listed on the MSDS.
