Cove Cuts on a Radial Arm Saw

Step 6 What the saw manual suggests

I bought an additional manual on using my radial arm saw.  It gave a procedure for making a bowl cut, but I saw some potential problems with it.  The first step was to lift the indexing pin and hold it lifted, which is not an easy task even when a sharp saw blade is not spinning at 3000 rpm a few inches below.  The second part of this suggested operation is to loosen the spoon handle lever (green arrow).  If it is loosened fully, the yoke and motor have some undesirable movement that will result in uneven cuts.  The spoon handle lever can be loosened just enough to allow the motor to swivel, but this is an uncertain process.  I would rather have things locked down so nothing is left to chance.  There is one more part of the suggested process.  See the next step.
