Re: [CAD_CAM_EDM_DRO] rough digitizing using proximity sensors

Hi Doug,

I checked MSC direct online, and didn't see a page # mode. can you
supply model # and mfg for those of us without catalogs?

I did manage to find some 2" delrin (sp?), so I may just make my own
vers. of a Renishaw probe. I hope this photo probe has a small shank,
gotta fit a Sherline!
