Subject: [CAD_CAM_EDM_DRO] Re: Newbie Questions

A couple of years ago, before being donated a full sized mill, I
posted a circuit on metalwebnews about how to build a head position
sensor with a dual element photoresistor and a laser pointer. It
proved to be accurate to about +- .002 of head deflection on a mill
drill. Contact me off list and I will try to dig up my old circuit
and some pix of the unit.
