Dart Boards vary in price from the cheap to the very expensive. A nice professional board can be acquired for under $50.00 along with two decent sets of darts. Cheap boards can also be fun, but you will find that the darts accompanying them suffer somewhat in balance and accuracy.

he board itself should be set up with the bulls eye exactly 5 feet 8 inches from the floor. It is wise to place some type of board behind (and around) the dart board, just to save your drywall or panelling in case of complete misses.

The board itself is 18 inches in diameter and divided into 20 sections. The section marked 20 is always centered at the top.

The toe line (also known as the oche - named for a brewers case - Hockey - that was originally used to establish the distance between the board and the toe line) should be exactly 7 feet 9 1/4 inches from the face of the board. The line on the floor may also be a raised bar, 1 1/2 inches in height and two feet long. In most homes this will be an unwanted obstruction so a piece of masking tape is often used. A convenient way to mark the toe line, protect the floor, and preserve dart tips is to get a dart mat.

There should be at least two sets of 3 darts. Each player or team uses a set (a player may even own his own set). The darts themselves have a maximum length of 12 inches and a maximum weight of 50 grams.

Generally, a chalkboard, hung near the board is used for keeping score.

To grind the tungsten electrode to a point, use a grinding wheel (Borazon® or diamond) specially designated the purpose to help prevent contamination. Grind the tungsten electrode straight on the wheel  (i.e. not at a 90-degree angle) to ensure that the grind marks run the length of the tungsten electrode, which reduces ridges that can lead to arc wandering. To ease arc starting and ensure a focused arc, grind the taper to a distance of no more than 2.5 times the electrode diameter (e.g. the taper on a 1/8-inch tungsten electrode should be 1/4 – 5/16-inches long).
Note: when grinding thoriated tungsten electrodes, make sure to control and collect the dust, have an adequate ventilation system at the grinding station and follow manufacture’s warnings, instructions and MSDS.

Truncated Tungsten Electrodes
For higher current applications, a truncated or flat tip works well. The flat land helps prevent the tungsten electrode from being transferred across the arc and/or from balling. Start by grinding the tungsten electrode to a taper (as explained above) and then grind a .010- to .030-inch flat land on the end.

Selecting the right tungsten electrode for the material being welded and the power source available are good first steps in ensuring positive GTA welding performance. Take the time to learn which is best for the application at hand and learn the proper technique for preparation. Doing so can minimize problems with arc starting and stability, contamination and more.

Darts is a fun social game that has been around a very long time. Its enduring popularity reveals it to be a sport that combines talent, skill and even a bit of luck.

The history of darts goes back to the days of the Longbow in Medeival England.

The setup for the dartboard is fairly simple, but it is rigid and for the sake of uniformity should be done as precisely as possible.

Safety is a prime concern playing with darts, because they can be dangerous if handled improperly.

The basic rules of darts are simple, fun and provide for a competitive game.

There are many variations to the rules for darts. We give you the flavor of a few.

Learning how to throw darts is fundamental to becomming a good dart player.

Depending on the type of tungsten electrode, preparation consists of creating one of three shapes: balled, pointed or truncated. Following are recommendations for each:

Balled Tungsten Electrodes
The balled shape is common for pure tungsten electrodes, particularly for the AC process on sine wave and conventional squarewave GTAW power sources.  To ball the tungsten electrode, apply the AC amperage recommended for the electrode diameter. The ball will form itself. In order to reduce the risk of the tip falling off or causing arc instability, the diameter of the balled end should not exceed 1.5 times the diameter of the electrode. For example, a 1/8-inch electrode should form, at the most, a 3/16-inch diameter end.

Pointed Tungsten Electrodes
A pointed shape can be used for pure, ceriated, lanthanated, rare earth, and thoriated tungsten electrodes when using inverter AC and DC welding processes. It also works well for welding with lower currents on thinner materials, as it directs the welding current into focused arc and helps prevent them from distorting. It is not recommended to use a pointed tungsten electrode for higher current applications since the tip can come off, leading to contamination.
