The Oliver has 6" grinding wheels, My Delta wolverine has 8" does the angles change?
Thank you

The big difference is the increased concavity of the bevel on smaller wheels. A micro bevel and or honing corrects for the concave bevel.
The concave bevel is a tiny bit harder to control since the cut wants to follow the bevel. A tool with a concave bevel wants to cut deeper all by itself. I hand sharpen my spindle tools so they have a flat or convex bevel.
Bowl gouges I use straight from the grinder.
The angles are not dependent on wheel size -bevel angles depend on the supporting geometry of the mechanisms - platforms, vee pockets etc.
