Awesome! I use the Norton as well and was eeally surpised at how long it takes with lapping them down to flat. I used a DMT 220 alternately under running water and it took about 15-20 minutes per side using figure 8s and decent pressure. When you lao your Norton remember to do the edges as well. I can't remember which video on the site it was but it was a video of a Meeting where they were doing a lapping demo and they mentioned lapping down the edges to further protect the razor during honing.
