![]() ![]() Stainless steel, a special form of steel that resists rusting and contains up to 10.5% chromium, is one of the two most common materials used for taping knife blades. The differences between the materials may not be apparent at first, so let’s break them down. Carbon steel knives are relatively uncommon, though you may encounter them occasionally. There are, generally speaking, three materials used to form the blades of taping knives: stainless steel, carbon steel, and blue steel. The most important factor when choosing a six-incher is flexibility, which brings us to: Blade Material For this reason, many professionals choose to have several six-inch knives on hand for a given project. It is fairly well-suited to both mud application and detail/finishing work, and as such, is typically the most-used size. The five inch or six inch knife deserves special attention, as this middle-sized knife fills a special niche. These larger knives are commonly called taping knives and have a square shape to them. These knives are great for smoothing the tracks left by smaller knives, feathering mud, and generally leaving a clean surface at the end stages of the project after detailing has been completed. Larger knives (6” and greater) are great for finishing, since they allow you to cover more ground with lighter pressure. Smaller knives are more likely to leave marks and uneven surfaces, but in the initial stages, that’s okay, since you will come back to do another coat. This is designed to allow the knife to fit into corners without damaging the wall. ![]() Joint knives are also rounded with sloping sides. Their smaller size allows you to get into smaller spaces and crevices, as well as use more pressure to force mud into seams and the holes left by screws. Smaller knives, (6” and smaller) are commonly known as joint knives, and are best for the first stages of a project. Size may be the single most important consideration in choosing a taping knife, as the size determines what stage of construction the knife is suited to. How are you supposed to know which knife is right for you? This guide to the all the possibilities will take the guesswork out of choosing the right knife for you and your project. However, the number of options can be overwhelming: size, handle material, blade material, special features. A true workhorse, most projects would simply not be possible without a taping knife.Ĭonsidering how important taping knives are, it’s critical to choose the right one for you and for your project. They are used for applying mud, finishing, laying tape, and more. Rep.Taping knives are an indispensable part of every drywall professional’s toolkit.

Even though the running speed of motor is set at 3000 RPM (50 Hz), the resonance does not occur since the disturbances during operation has shifted the transient vibrational peak to about 100 Hz with considerable low amplitude of 1.506 m/s 2. From the study, the first sixth modes of the structural have been determined in the range of 0–100 Hz, and the most dominant mode resulted at 54.88 Hz. By using ANSYS v20 software, the RTM structural vibration in terms of modal, frequency response and transient analyses are investigated. The designed RTM using rotational cutting tool can complete the tapping process in faster time with minimum labor contact. In this study, a new concept of intelligent rubber tapping machine (RTM) is introduced as a solution to this problem. However, the number of skilled rubber tappers are getting lower nowadays, and the available manual tools are unable to cope with the market demand. ![]() Due to this, it is necessary to improve the quantity of natural rubber that been produced. Rubber products are important and took up about 20% of Malaysia’s total exports since year 2000.
