A Short History Of Sand Paper

The fist evidence of a precursor to modern sandpaper dates to around the first century of the Common Era.

Human beings have understood the properties of abrasives for tens of thousands of years. There is plentiful prehistoric evidence of stone tools that have been precisely ground to hone an edge, and of early artwork and devotional figurines that have been polished and shaped using grinding materials. Early abrasion was usually performed with stone tools, but by the Chalcolithic era -- the first phase of the Bronze Age, metal tools were often also used to scrape and polish materials into their desired shape and finish.

The fist evidence of a precursor to modern sandpaper dates to around the first century of the Common Era. Archeologists have found evidence of Ancient Chinese craftsman using a mixture of ground shells, grains of sand, and hard seeds that were bound to a parchment backing using naturally occurring gums as an adhesive. The rough surface created was suitable for much the same use as modern sand paper, though it was much more complex and costly to produce. Natural materials such as shark skin were also used as abrasives in the ancient world.

It was not until the 19th Century, a time of leaps and bounds of technological progress, that a truly affordable and mass produced abrasive paper entered the marketplace. British inventor John Oakey is credited with having created the direct forebear of today's sand paper in the 1830s. His company produced a glass paper that consisted of "glass fit", a ceramic material, bonded to a paper backing and produced in large sheets.

Glass paper remains in use for much of the century. In the early 20th Century, developers working for 3M came up with a sandpaper made using silicon carbide grit as the abrasive. This remains a formula commonly used for sandpapers today. The backing used in sandpapers has continued to improve over the past few decades, with common materials in use today including thick papers, polyester, rayon, and other synthetic fabric-like materials.

Sandpaper with thick, durable backing is imperative for use with modern power sanders, and in particular with belt and bench sanders, which produce a surfeit of force. Great sandpaper paired with a great sander makes the job of the modern woodworker easier than his or her ancient predecessors could ever have imagined.

Choosing A Great Belt Sander

The term belt sander is something of a blanket expression that can be used to refer to many different power tools, the common thread being that they use a belt of sand paper that rapidly spins around drums which hold it taut. Some belt sanders are handheld, and are moved over the surface of the object to be smoothed. Others are larger and sit atop (or are affixed to) work tables; these units are usually called bench sanders. Still other large, industrial grade belt sanders are large enough to sit on the floor themselves.

Belt sanders can be used with a range of materials beyond woods, as well.

Choosing the right belt sander for your needs means carefully considering your line of work or your hobbies. For example, if you are a cabinet maker, a powerful bench sander might be a great choice, allowing you to quickly finish the surface of drawers and doors that will then be affixed to the frames you have designed. If you are a carpenter who builds or refinishes larger pieces of furniture -- those much too large to be maneuvered by hand -- then a handheld belt sander is a good choice, as you can move it around the large items on which you're working.

A belt sander packing plenty of power but that is still company enough for handheld use is also a great tool for anyone installing or refinishing a floor. Belt sanders can quickly strip away old varnish, stain, and damage, revealing lovely hardwood flooring that is ready to be refinished beneath the wear and tear.

Belt sanders can be used with a range of materials beyond woods, as well. Plumbers who need to polish the ends of PVC or metal pipes can easily do so with a belt sander and the right toughness and grit of paper, and a machinist of mechanic looking to remove bits of metal from a nut, bolt, or other component can do so quickly and deftly with a belt sander.

Proper Belt Sander Use And Maintenance

Belt sanders are powerful tools. If used improperly, can not only damage the item which you are hoping to build, restore, or improve, but they can cause serious bodily injury as well. Proper operation of a sander means proper attention to safety concerns.

Replace sandpaper often during the course of a job to ensure you are doing to best possible work.

As a belt sander produces lots of dust, proper mouth and nose protection are essential; it is too easy in accidentally inhale the minute particles created by power sanding to risk doing so without protection your respiratory system. Protective eyewear is also highly recommended during operation of a belt sander, as the fine sawdust created can be a sever irritant, and as larger bits of material can occasionally be thrown upward by the sander. A sander should also be operated with gloves to prevent injury to the hands and fingers.

Even a great belt sander is only as effective as the sandpaper its user chooses. Select the right grit of sandpaper for the job at hand, remembering that the higher the grit number, the smaller will be the particles on the paper's surface, and thus finer the polishing job it can complete. (e.g., 1000 grit paper will sand more slowly but more precisely than 200 grit paper). Replace sandpaper often during the course of a job to ensure you are doing to best possible work.

Take the time to clean out your sander's exhaust port after each use, and make sure you wipe down any object to be sanded before you commence work to remove any material that is already loose on its surface.
