Mini table saws are typically 4 inch, while micro table saws are less than 4 inch, although the naming of the saws is not well defined.Mini and micro table saws are generally used by hobbyists and model builders, although the mini table saws (4 inch) have gained some popularity with building contractors that need only a small saw to cut small pieces (such as wood trim).
Being a fraction of the Check Dewalt Scroll Saw Reviews size (and weight) of a normal table saw, they are much easier to carry and transport.Being much smaller than a normal table saw, they are substantially safer to use when cutting very small pieces. Using blades that have a smaller kerf (cutting width) than normal blades, there is less material lost and the possibility of kickback is reduced as well.
In the United States, perhaps the first recorded patent for the circular saw was issued in 1777 to an Englishman, Samuel Miller; it refers to a circular saw that was created in Holland in the 16th or 17th centuries. The 1885 catalog of the W.F. & John Barnes Co., Rockford, Il. clearly shows a classic table saw and it is labeled as a “Hand [Powered] Circular Rip Saw”.
Table saws are especially dangerous, because the operator holds the material being cut, instead of the saw, making it easy to accidentally move hands into the spinning blade. In contrast, with other types of circular saws, the material remains stationary, as the operator guides the saw into the material.A dust extractor should be fitted if sawdust is prone to build up under the cutting blade. Through friction the spinning blade will quickly ignite the accumulated dust, and the smoke can be mistaken for an overheated blade. The extractor also reduces the risk of a dust explosion and facilitates a healthier working environment.
The magnetic feather board was developed in 1990. The patented Grip-Tite is held to a cast iron table top or steel sub fence by high strength permanent magnets. The advantage of a magnetic feather board is the fast setup time on any cast iron tool deck or steel faced fence.
When used in conjunction with a steel faced rip fence, they are used to hold down ripped wood on any saw deck and prevent kickback. Feed wheels added to the Grip-Tite base pull ripped wood to the fence, allowing the operator to rip wood on any table saw with no hands near the blade.When a table saw has a table top made of a material other than cast iron, like aluminum, then a miter slot featherboard should be utilized to keep pressure on the stock against the fence when otherwise your hand would be in dangerous proximity to the saw blade.
Keep in mind that this style feather board does take more time to set up than the magnetic style when deciding on a tool purchase. If a safety device is more convenient then it may be more frequently utilized. Never place a feather board past the leading edge of the blade or else kickback will occur.In recent years, new technology has been developed which can dramatically reduce the risk of serious injury caused by table saws.
