If flash rusting occurs prior to coating, further chipping, cleaning and sanding may be necessary. Since bare metal surfaces will flash rust soon after exposure to the atmosphere, paint should be applied as soon as possible after chipping. It is also important to check the surface for oil deposited during chipping, and if necessary, clean the area with solvents. Prior to painting, it is desirable to feather any edges between metal and old paint. Then the process is repeated until the desired area is completed. Two to three passes over an area is generally sufficient to clean it. It is recommended that an area no larger than 6 to 8 inches (150 to 200 mm) be cleared at once. It is used most effectively by holding it at a 45° angle to the work surface. Then, the needle gun is used to remove rust, loose scale, and paint, leaving bare metal. This can be done with solvents or with a combination of detergent and fresh water. It is recommended that before needlegunning, a surface should be prepared by removing oil, grease, dirt, chemicals and water-soluble contaminants. A needle gun can clean an area to bare metal in seconds, and compares well to other scaling tools in terms of accuracy and precision. Its main advantage is that the needles automatically adjust themselves to contours, making the tool a good choice for cleaning irregular surfaces. The needle gun has advantages over other scaling tools. This movement causes the needles to move back and forth against the work surface. In a pneumatic unit, compressed air forces a piston forwards and backwards. Many models use compressed air, although electrical needle-guns do exist. Different models offer choices of number of needles, operating speed, and power levels. The tool forces these needles against a work surface at variable speeds up to around 5,000 times per minute. Operation and use Ī needle gun has a set of very fine chisels known as needles. The tool is used in metalwork applications as diverse as home repair, automotive repair, and shipboard preservation. Ī needlegun scaler, needle scaler, or needle-gun is a tool used to remove rust, mill scale, and old paint from metal surfaces. A US Navy Seaman uses a needlegun to remove old paint and corrosion aboard USS Kitty Hawk. These handheld, air-powered tools are lightweight to minimize. They are commonly used to remove rust, paint, dirt, and welding slag from metal surfaces. For more information on vibration reduced needle scalers be sure to check out our blog on Low Vibration Needle Scalers.Hydraulic or pneumatic tool used to remove rust and paint A US Navy dockyard worker operates a needlegun while wearing vision, hearing, and respiratory protection. Needle and chisel scalers use lighter percussive action than air hammers to rapidly and repeatedly strike a bundle of needles or a chisel against surfaces to clean off coatings and buildup. Call for details.Īlso, be sure to inquire about our new line of vibration reduced tools which allow for better ergonomics and less on the job fatigue. 7" length and chisel tip needles are also available upon request. Most replacement needles come in 19 needle sets, measure 5" in length and feature the standard round shape. International Air Tool Company offers replacement needle sets in standard steel, stainless steel, and beryllium copper materials. The former being better for paint and rust removal, while the latter more effective for welding flux removal. Some needle guns hit faster with shorter strokes, while others hit less frequently, but with longer strokes. Needle scalers, (also commonly referred to as needle guns), are versatile percussive tools that can reduce the number of man hours required to perform surface preparation tasks. Needle scalers are used across many industries, but are especially useful in shipyards, foundries, and mechanical tank cleaning. Choose from a wide range of top quality air needle scalers such as: I ngersoll Rand, Chicago Pneumatic, Desoutter, Cleco, Sioux Tools, Texas Pneumatic, Michigan Pneumatic, Master Power and more. International Air Tool Company offers both inline and pistol grip varieties. Pneumatic needle scalers, needle guns, and chisel scalers are used to accomplish a variety of surface preparation tasks such as the removal of welding slag, scale, rust, and paint.
