John, if you do not mind, a couple of questions. How much did you pay for the CHNC
and How hard was the retrofit. Was it all about pushing wires and computer setup (like it was with my mill, sans encoder mounting), or did you have to do a lot of precision machining and parts fitting? Did you reuse existing encoders? Exciting! i On Wed, Nov 17, 2010 at 6:07 AM, John Thornton <[email protected]> wrote: > That was my plan for my Samson manual lathe from the git go until my > Hardinge CHNC showed up at my door step.
