10 inches = 504rpm. 5 inches = 1,008rpm. 2 inches = 2,521rpm. At 1inch, the spindle would be humming along at 5,042rpm, a dangerous speed for a workpiece that large. Do the math if you don’t believe me: (3.82 x 1,320)/1 = 5,042. This illustrates an important point: The smaller a turned diameter, or the diameter of a rotary tool, the ...
