Re: [CAD_CAM_EDM_DRO] Stepper Dissasembly

Hi Chris,

4) I'd see if Dan Statman is still looking for defunct motors! He
needed some dummies for temp. use on a new Sherline mill. Seems he got
a Mill with CNC mounts on it already (lucky dog), and doesn't have
motors yet!

Otherwise, I'd go with 1) Paperweight!
