My Norton saga continues...
Well, after a couple of weeks and trying several different strategies, I'm still getting a gritty feeling on the 8k side of my Norton. I think I may have figured out the problem, though.
So question first, then background: Does the 8k side of your Norton have tiny pits in it?
I can see small pits in the surface of my hone when I hold the 8k side under my desk lamp and turn it so that the surface runs almost perpendicular to the light. That gives me a very strong sidelight, which exaggerates shadows. If I look very closely the pits seem to have white at the bottom of them.
The 8k side of my stone has felt gritty ever since I bought it. I've lapped it several times with 400 and 800 grit 3M sandpaper. It used to be really bad no matter what I did. After several lappings it now allows me to do one stroke in each direction without feeling gritty. Then on the second stroke the edge starts to catch, sometimes really badly. If I douse the stone with water again and rub my hand over it, I can get another smooth stroke in before the cycle repeats.
I'm thinking that the pits might be from air pockets in the hone or something, and that as long as they're full of water they're OK. If it's not normal to have these, maybe I can lap them out or get my stone replaced. Somehow I think lapping may remove some of them but open up more elsewhere on the stone.
Thanks for any help you can offer,
Josh
