    ok, I just ran the nickel test, past with flying colors. So I got curious, I tried the dime test. The dime was hard to get to stand upright, and fell almost immediately when I turned on the saw.

    Then I realized why, I didn't have the guard on the blade, the wind from the blade blew it over. After I put the shark on, the bt passed the dime test.

      I've had nickels that I could not balance on a flat table, let alone on a saw that was running. Seems like one of those silly "bragger rights" tests. I guess, a really smart person would stand a nickel on edge, and then determine how much / type of vibration actually was needed to knock it over, and then make some sort of a statement to the validity of the test to begin with...

          Ok guys, what did i do wrong.

          I set a nickel on my saw and started it, knocked the nickel over with the smt, it hit the blade and i only could find a quarter on the floor.
          What you did was realized a 400% return on investment!!

          If you did just one roll of nickels per day for a year, you'd have a profit of $2,920!!

            I used to have one of those cheapo direct drive Craftsman 10" saws.
            It was a horrible saw but I did practice good work habits with it.
            I always secured it to the work table with two or three clamps.
            I always kept all tools and loose stuff off the top of the saw because if I ran the saw with them on, they would all be on the floor in 30 seconds or less.
            I used to have a Craftsman saw as well. I couldn't leave my push stick on top of the saw because when I'd reach for it at the end of the cut it would be on the floor.

            On the other hand, I could glue a piece of sandpaper to the table and it would do double-duty as a finish sander!

              Uh oh, don't get me thinking too much on this.

              As such it's a qualitative test.
              Because vibration is 3-D (X, Y and Z-components)
              Z-vibration alone in excess of 1g (32 ft/sec/sec) will bounce the coin and set it flying.
              But X axis Motions (perpendicular to the face of the standing coin) exceeding in amplitude half the width of the coin will cause the coin to fall over(making the center of gravity move outside the footprint of the coin)... lessee Accel = second derivative of (.037" sin 2 x Pi x 80hz x t)...

              OK, this is even making my head hurt...

                ROFLMAO! Your opening line and your closing line were the only ones I can relate too. Funny thing is I think I get the point?

                  Loring,

                  It is making my head hurt too. I look at it in a much simpler way: Is there enough vibration there for you to notice and/or make cutting uncomfortable and/or affect the accuracy of the cuts?

                    80 hz? At first I was thinking "80 Hz?, why not 60Hz". Oh yeah, spindle RPMs are 4800 RPM = 80Hz. So, a simple quick fix to all TS's to ensure they pass the $0.05 test is to leave the saw off.[)]

                      The dime test works best with Superglue...it barely shows up either, so no one will know. [)]

                          LMAO @Larry,

                          I dunno about you guys, but I doubt if I could stand a nickel on edge on a tool even when it's not running:-)

                          After balancing that nickel on edge, scrounge up another $1.95 and head to the nearest Dunkin Donuts, where the nickel trick and $2.00 might get you a cup of coffee (of course the gas to get there may require a second mortgage on the house).

                                Okay, I finally got around to trying the nickel test and my saw passed. Now, what do I do?
