Thanks Justin. This post was what I saw to be something that is often overlooked. Polishing the ramp is some thing that had covered that at least a few times and this post was not meant to go into a complete bolt work over. Maybe I should have gone that route. Your post reference was multiple pages an was all rimfire so if I overlooked your intent please provide a little more info. Thanks.

As for the water or oil, I use light oil(I actually use Kroil) because it is near my workbench, water is harder to keep on the work surface due to surface tension where oil has better adhesion properties. I have not seen my diamond hones or the media effected by the use of oil. I guess it could effect some plastics. I will leave that choice to the owner.
