Needlegun scaler

Operation and use

A needle gun has a set of very fine chisels known as needles. The tool forces these needles against a work surface at variable speeds up to around 5,000 times per minute. Different models offer choices of number of needles, operating speed, and power levels. Many models use compressed air, although electrical needle-guns do exist.

In a pneumatic unit, compressed air forces a piston forwards and backwards. This movement causes the needles to move back and forth against the work surface.

An able seaman uses a needlegun to remove scale while refurbishing a mooring winch.

The needle gun has advantages over other scaling tools. Its main advantage is that the needles automatically adjust themselves to contours, making the tool a good choice for cleaning irregular surfaces. 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.

It is recommended that before needlegunning, a surface be prepared by removing oil, grease, dirt, chemicals and water-soluble contaminants. This can be done with solvents or with a combination of detergent and fresh water.

Then, the needle gun is used to remove rust, loose mill scale and paint, leaving bare metal. It is used most effectively by holding it at a 90 angle to the work surface. It is recommended that an area no larger than six to eight inches be cleared at once. Two to three passes over an area is generally sufficient to clean it. Then the process is repeated until the desired area is completed.

Prior to painting, it is desirable to feather any edges between metal and old paint. It is also important to check the surface for oil deposited during chipping, and if necessary, clean the area with solvents. Since bare metal surfaces will flash rust soon after exposure to the atmosphere, paint should be applied as soon as possible after chipping. If flash rusting occurs prior to coating, further chipping, cleaning and sanding may be necessary.

.410 Bore $62.13 High Quality Content by WIKIPEDIA articles .410 bore, commonly misnamed the .410 gauge, is the smallest gauge of shotgun shell commonly available. It has similar base dimensions to the .45 Colt revolver cartridge, though the .410 is significantly longer, up to 3 inches (76 mm) in length), allowing many single shot firearms and some revolvers chambered in that caliber to fire shot without any modifications.
