Best Scroll Saw to Buy in 2018 - A Definitive Guide

Best Scroll Saw 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. The Consumer Products Safety Commission (CPSC) estimates that there are 67,000 tablesaw-related injuries every year and 4000 amputations.One new feature, commercially available in saws since 2005 is an automatic braking system.


The feature's inventor, after trying to license it to manufacturers without success, started SawStop, based in Tualatin, Oregon. SawStop's saws apply a small amount of electric current to the blade of the saw. This current is continuously monitored. If the saw detects a change in this current (as would occur if a hand or other body part came into contact with the blade) an automatic braking system is activated, forcing an aluminum brake block into the blade.


The saw stops within five milliseconds, and angular momentum retracts the blade into the table. The operator suffers a small nick instead of an amputation or other more serious injury Following an activation incident, both the blade and braking cartridge must be replaced The automatic braking feature must be bypassed when cutting conductive material, such as wet timber.


There are two competing schools of thought when it comes to properly setting the height of the blade for sawing. The first is commonly expressed thus "Only allow the blade to rise above the work by the amount of finger you wish to lose." That is, the blade should protrude above the piece as little as possible, to prevent the loss of a finger in case of a sawing accident.Another competing view is that the saw functions at its best when the angle of the blade teeth arc relative to the top surface of the workpiece is as extreme as possible


This facilitates chip ejection, shortens the overall distance through which the teeth act on the part, reduces power consumption and heat generation, substantially reduces the peak pushing force required, thus improving control, and causes the blade's force on the wood to act mostly downward rather than largely horizontally.


Although the majority of table saws are used for cutting wood, table saws can also be used for cutting sheet plastic, sheet aluminum and sheet brass.Outfeed tables: Table saws are often used to rip long boards or sheets of plywood or other sheet materials. The use of an out feed (or outfeed) table makes this process safer and easier. Many of these are shop built, while others are commercially available.Infeed tables: Used to assist feeding long boards or sheets of plywood.


In the past roller stands were pretty much the only option, but there are now commercially available infeed units that are more efficient and easier to use.Downdraft tables: Used to draw harmful dust particles away from the user without obstructing the user's movement or productivity. Rip fence: Table saws commonly have a fence (guide) running from the front of the table (the side nearest the operator) to the back, parallel to the cutting plane of the blade.


The distance of the fence from the blade can be adjusted, which determines where on the workpiece the cut is made. The fence is commonly called a "rip fence" referring to its use in guiding the
