Several people have asked for various kinds of help with their radial arm saws. Many of these requests would be solved with a manual, but that has often been lost by a previous owner. This Instructable will take the reader through the steps involved in setting up a radial arm saw. Tools needed are: a couple of Allen wrenches, a couple of good squares, a screwdriver or two, a 7/16 inch, a 1/2 inch and a 9/16 inch wrench and a block. A hammer is also handy, but not absolutely necessary.
Power saws go out of alignment through the vibration that accompanies use. Also, radial arm saws do not like to be moved, and settings will probably drift when one is moved. But, a lot depends on how much precision the user is looking to have from his saw. If you plan to use the saw only to cut 2 x 4s to length, the accuracy you need is not the same as if you were doing fine cabinetmaking with the saw.
Step 1: Assemble the stand
This is my homemade stand constructed of 2 x 4 pieces and plywood cleats. I made it to take down easily, so the brace pieces attach with corner brackets and wood screws. I made two tool trays that rest on cleats inside the frame assemblies of the stand. You want a stand that makes the table on your saw a comfortable height for working. Commercially made stands are also available.
I like to have my saw away from the wall. For one thing, this allows me to hang blades and other fixtures on the back of the saw stand. It also allows me to walk around to the back of the saw rather than reach over the table for some set up and service procedures. And, I want to be able to put pieces of lumber eight feet long onto the table and take them off of the table from both sides of the saw. Workshop space is somewhat limited. Moving the saw out from the wall allows me to pass lumber in front of my workbench when things like my vise would otherwise obstruct.
