  • Cutting simple curves on a vertical mill Woodwork

    2013-3-1 · Cutting simple curves on a vertical mill I'm looking at getting a simple small vertical mill like the Sieg X2. Hand filing, whilst a useful skill, is seriously tedious. Ignoring the vertical (Z) plane, how are simple curves cut on a mill? Do you have to just walk the cutter along the curve in an X-Y step fashion?
