Thread: Lapping a Naniwa Super Stone

I recently purchased a Naniwa Super Stone 12k but have not used it. It is in the plastic base. Just wondering how wet it should be to lap it. I am going to use sand paper and a granite tile for lapping. Should i just spray a little water, lap it dry, put a big puddle on the sand paper?

The stone should be wet while lapping it. Just keep it wet and you'll be fine.

Thats what i thought. the only reason i ask is cuz i know others have had bulging trouble if the stone is too wet and its not supposed to be soaked like the nortons...thanks

Yeah soaking is not a good idea since SuperStones use a resin binder which can swell and get mushy.
