I'm working on a wedge right now and it is taking a little time to get sorted out on my norton 4k. I probably should invest in a 220/1k stone, but that is a different topic.

I have been lapping my 4k roughly every 50 laps of the razor. I usually end up needing to flatten my stone based on the pencil lines when lapping. I am trying to set the bevel and know I need to remove a lot of material. I am using a lot of pressure.

Anyone else find themselves lapping this often.
