Not sure about your grinder conversion, send a couple photos to my email. I may have some ideas. There is a new posting on the Home Made Tools forum by me that has my email and a link to https://grabcad.com/library/mill-drill-sharpening-jig-1 that you might consider if you have vertical mill capability. It is a sharpening jig for mills and drills... also can be used in fabricating new cutting tools. I designed tools, jigs, and automated machinery for 20 years of my 35 years as a professional in engineering. Retired, and make very high end knives "full time" (and momma "to do list" takes the rest of my time), so spend 10 hrs a day in garage running machinery that I built or modified.
