Okay, I'm trying to hone my first razor with my new, and freshly lapped, Norton 4/8. My question is how much "pressure" do you start out with on the 4000 when setting the bevel? On the videos I have watched it seems like the water turns grey on the stone as they are circling, or whatever method they are using, and I'm not getting that. Should I press a bit more or just stick with it longer on my current pressure? Thanks for any help!
