When the luthier’s $1,200 CNC malfunctioned mid-soundhole cut, the burl maple top puckered like bad wallpaper. Then the Milescraft 1219 clamped onto my router. This aluminum wizard carved a 7.5" soundhole within 0.003" tolerance, rescuing the build with arcs smoother than a lathe turn. For instrument makers, custom furniture shops, and DIY warriors, this isn’t a jig—it’s forgiveness forged in metal.
