There are several things that you need to consider when building a contact sword. These include its Center of gravity, Handle design, Safety precautions, and Materials. By the end of this article, you should have a functional sword. Then you can use it to defend yourself or defend someone else. Here is some information that may help you in your project. This article covers all of the important aspects that you need to consider when making a contact sword.
The Contact Sword is a type of padded martial arts sword. Its blade is a life size cross section of an ARMA contact sword, with a quarter for scale. It is made of 7075 aluminium, which is both light and strong. It also has an arc-shaped handle, which is more comfortable to hold for a longer period of time. It is easy to balance and construct compared to other versions of the sword.
A sword’s handle, known as the grip, is an important component. While the blade and the handle are made of metal or wood, a hand-held version is generally more comfortable to hold. The grip is usually wrapped in a material, such as leather or wire, that provides a secure grip. Traditionally, shark skin was used to cover the grip, but rubber became popular in the late 19th century. However, many swords today use ray skin, which is similar to the leather that is used in katana construction.
Center of gravity
The Center of Gravity of a contact sword is the center of mass. It determines where the sword will balance, and where the blade’s torque is equalized. Too much weight at the hilt of the sword will make it difficult to execute fluid strikes. The weight should be evenly distributed along the entire blade, so that it will rotate at the same speed and resist twisting during strikes. Bladesmiths have been designing swords with specific points of balance throughout history.
The center of mass, or point of balance, is the precise, physical point on the sword that is in balance with the wielder. If the weight of the blade is balanced on the tip of a finger, the sword will fall to the side of the finger carrying most of its weight. However, this can lead to injury. Therefore, it is best not to try to balance a sword on the tip of a finger.
While the Center of Gravity and Center of Percussion are directly connected, the two concepts are not the same. For example, when you use a contact sword, the tip will hit something, but will not strike it at the Center of Percussion. Because of this, the sword will stop before it reaches the Center of Percussion. As a result, the sword will not transmit the force to the user’s hand.
Another method of determining the Center of Gravity is called harmonic balance. To determine this, reverse the direction of the blade, and tap the pommel with the heel of your hand. Locate the section of the grip that does not vibrate. Different swords will have their second node of non-vibration in different locations. The location is an important consideration for a proper balance, and a sharp blade can cause serious injury.
When making a contact sword, there are a few important rules to follow. First of all, you must never lock your elbow joint. If you do, your arm will become rigid, and the force transferred to your hand will be wasted. Secondly, you should never lunge with your sword. During lunging, your body weight is attached to your shoulder, not your arm. Second, you should never use the full fencing lunge. This action will cause the sword to become unstable, transferring force to your hand and the hilt of the sword. Also, avoid putting white gas in your sword. This will reduce the life of the kevlar and could damage the silicone disc. Third, a contact sword should not be used in combat.
Third, when making a contact sword, you must keep enough space between the sword and the unprotected person. Another important rule to remember is to never fence in shorts or open-toed shoes. They may rip or cut a fencer. If you do not wear proper clothing, you are not allowed to fence. Do not risk your life by not following these safety rules. If you are not sure of the rules, read this article carefully.
There are two main types of steels used for functional swords. AISI 1045 and AISI 1060 are both made of carbon steel, but they are not appropriate for use in a contact sword. Low carbon steels contain between 0.05 and 0.15 carbon, and are primarily used for fittings and fitting parts. They are less expensive than other steels, but they don’t make good swords.
A good contact sword will have a counterweight made of 500g steel wrapped in a durable rubber overlayer and a soft underlayer. The counterweight is the main component of the sword, accounting for more than half of the weight. By distributing the weight evenly, the sword will roll easily during contact maneuvers. For the handle, ARMA suggests using double thickness, sustainable natural rubber. If you don’t feel comfortable with the material used, replace the grip after a season.
To shape a blade, Japanese sword makers coat the blade with a wet clay mixture that hardens and retains heat as the blade cools. This process has been around for centuries, but wasn’t widely used for making contact swords until the 19th and early 20th century. It saves time and materials, but is less effective than the previous method. Additionally, it’s difficult to find rarer steel, so some bladesmiths use a blend of both types.
Once you have the material, you can start designing the blade. Try to find traditional swords from different time periods to get a better idea of what shape to aim for. Sketch out your design on a piece of paper and make a template using a cutting board. Once you have a rough outline, cut the stock steel to the desired length. Then, heat the steel until it turns yellow, which indicates it has reached a temperature of 2100 degrees Fahrenheit or higher.
There are a few basic steps in the construction of a contact sword. A blade is forged from oak slats. The pommel is attached with a threaded nut. The threading must be round, or nearly so, and the blade must be of the same thickness as the tang, or the width of the pommel at the point of the guard. The tang, or handle, must be the same diameter and thickness as the blade at the pommel, and it must fit into the guard. If it is not, the sword is likely to become weak, since the tang is the most vulnerable point in the weapon.
The counterweight is a large metal ball about 50mm in diameter, weighing 500g. The counterweight is molded rubber rather than rubber-wrapped. The handle has a spongy EPDM rubber base and a tennis racket grip. The handle is ergonomically designed in an hourglass shape, and has an extra layer of silicone that cushions the user’s hand. The weight is balanced by the balance of the handle, with the center of gravity marked for the dry and fueled weight. The center of balance of the weapon will shift as the fuel burns off.
The tang is another area where mistakes in construction can occur. For instance, swords with flames are not appropriate for combat because they can easily be damaged by other swords, and they are very difficult to perform contact moves with. If the tang is weak, the blade will be too heavy to use. The blade should have an even thickness. Those who use steel for swords should also make sure the blade has a flat surface and a thick tang to avoid the risk of warping.
