So I have been trying to figure out a more reliable/repeatable method to sharpen my HSS tools when it occurred to me that my dad's beat up old Ryobi grinder is collecting dust in the basement. Are the various grinder jigs available for sharpening designed to fit any grinder, or is it only certain models? If I can make it work, I will absolutely go ahead and slap a CBN wheel and a jig on this thing. Won't be as convenient, being in a separate location from the lathe I use but better than nothing! Photo of the grinder in question attached.
