I am flattening my waterstones for the first time. I'm noticing that on the Norton 1/4k they are very rough at the start. How much do y'all take off before using? In Lynn's video he talks about taking off 1/8". Really?

I currently have a chinese 8k and want to get a 12k. I did not find it on the woodcraft site. Am I looking in the wrong place? Any other soruces?

TIA
