A recent Design News magazine featured a neat article about a fellow that built a wood frame for milling machine. It uses a Dremel-type router for the spindle motor. It’s a hand-cranker, as my machinist buddies say, the only motor is for the spindle.
This manual milling machine uses a hand-cranked X- and Y-axis with a Dremel-type spindle.
Cool thing is, the builder, John Duffy used an Atmel-basedArduino board to make a digital readout. This makes the mill much more useful.
This Arduino is used to create a digital read out (DRO).
