Hello, and sorry if this has been answered in the past. I have searched the threads, but not found a thread explaining a newbie honer how to use sandpaper for lapping.

I have bought myself a Norton 4000/8000 and a Naniwa 12000 for Christmas, and hope to hone myself in the future. I also bought some 240 and 320 sandpaper. I have read about sandpaper and a glassplate, but what do you actually do?

And is it necessary to lap a new stone? Again, sorry if this is answered before, I can delete this post if so.

Thank`s

Arild
