Using Your Radial Arm Saw Safely
These saws are one of the most usefull tools in any work shop but a word of warning,always cut with your hands well away from the blade and never cut with your arm across the line that the blade may take,this also means could take if it jambed and lunged forwards.While you can rip timber with a radial arm saw I do not recomend this due to the fact the blade will then be on an upper cut,meaning the timber can lift up and in the worst case fly at you,I have seen this happen,the timber in question flew right across the work shop,not a great idea.
Read the manual from time to time,it will tell you how to set the machine up,drive belt tension and such like,use of various blades and probably how to fit a router cutter for running moulds too,Sharp blades are a must and the best are tungsten carbide tipped,well worth the extra cost as the cut better and last longer.
Radial Arm Saws
A radial arm saw basically consists of a motor (rather like a handheld circular saw) suspended from a long arm, in a yoke, which allows multiple degrees of rotation for the motor assembly. The motor assembly connects to the overhead arm by a carriage assembly that traverses the arm’s length when manually pulled by the operator. All parts of this assembly may be locked into particular positions as desired by the user. To achieve a simple 90 degree cross cut the saw is pulled from back to front, through a slot in the fence. To make a rip cut the motor head is rotated 90 degrees and positioned outside the fence parallel to it.
Radial arm saws were first developed by Raymond E. Dewalt in 1922 and were marketed under the name of the Dewalt "Wonder-Worker". Dewalt continued to manufacture radial arm saws until 1990 when they sold the rights to The Original Saw Company.
