  • Precision Cut-Depth Measuring

    I'm kinda new at this, and I was wondering if anybody knows a good way to measure the depth of a cut on a radial arm saw (prior to cutting of course) other than "eyeballing" the teeth of the blade at what "seems" like its azimuth with a small ruler?

    I frequently have a problem with EXACTLY duplicating a groove once I set the saw up for another cut and then return to cutting a groove which requires measuring the hight if the blade teeth from the table.

    Any Ideas?

    Check this link Wo odcraft depth guages Should be exactly what you need. I have one, and it works fine for both the TS and the RAS

        Vermont american makes a little aluminum depth gauge for about three bucks. works great, almost any home improvement place has em
        He who dies with the most power tools wins!

          Perhaps I misunderstand you question, but I usually use the existing dado cut to replicate the depth setting if necessary. The eye is better than any measuring tape. Make sure the saw is disconnected from power source. I raise the blade till the dado will slide under the blade. I then lower the blade until the deepest cutting tooth just kisses the wood. It is importatnat that the stock be of the same thickness as that used in the original cut. I have used a RAS for many years, and it is the best for dadoes.

          Hope this is helpful,

            Where it is critical to exactly measure the depth of cut, I use an old piece of 2x4 scrap, run it over the blade using the miter gauge, and then either measure the depth of the kerf cut or match it to the thing I'm trying to match. The Vermont American tool that someone mentioned is useful, but you have to be sure that you're measuring against the highest point any tooth will reach during a revolution of the blade. You could do this by placing the gauge over the blade, turning on the saw, and the slowly raising the blade until the gauge goes flying into space -- JUST KIDDING! I've used the guage by turning the blade by hand, but I like my scrap 2x4 method better.
