WW still works!

Yeah, you do need to pay attention. The idea is remove material until it's flat, and then start using a finer grit to make it smooth. I've read someone suggest making a grid of markings with a permanent marker, and when all of the markings are gone, then you have a flat surface. I didn't need to do this, because the first sink that I lapped was the anodized aluminum one on my 9500 pro. I'll be doing MUCH more lapping after I'm done milling my waterblocks.
