Thread: Norton "unflattening" stone?

Try Howard at The Perfect Edge - he's a member here, and will set you up (although shipping will still be a b@#*h). I got my coticule from him, and the customer service was excellent.

I tried it against several things, including a borrowed straightedge from my building's maintenance man. Yes, it's bowed. I used the Shapton in the photo because I know it's straight, and it was the easiest thing at hand for the purpose.

You could just use a granite tile from Rona/Home Depot and sand paper for lapping. This is the method I have been using since I returned my Norton Lapping stone.

Lee Valley took my lapping stone back even though I had used it a couple of times. No problem returning stuff if you have your receipt and are less than 90 days after purchase.
