Thread: Naniwa 8k cuts

Hi everybody!

Here is a pic of Naniwa 8k. On the edge, stone have a little cuts. It is possible to remove these cuts edges with something?

Pic is a little blurred, sorry.

you need to bevel the edges, Naniwas are fairly soft so not hard to do

I use the norton lapping plate from my norton kit (the one thing it's good for), or 400 grit wet and dry (used wet) would do the job fine

Well, A DMT plate would work, or some wet sandpaper. If your going to use sandpaper, try some 220 grit to start. The Naniwa's are soft, so it shouldn't take long...

As the others have already said, that hone needs to have the edges bevelled (and possibly lapped for good measure as well). Absolutely do not try to use that hone until those chips are gone

I have 3M sandpaper 400 and 600 grit. Is that enought for remove chips?

If it's wet and dry sandpaper that should be fine. And will be fine to lap it on as well. I've Lapped my norton on up to 800 grit. and that's harder than a naniwa (of which i have a 12k)

Bevel the edges first then draw a grid on and lap it second, should take care of things nicely

Thanks all for answrers!

Should be fine, the coarser grits just make it easier

I disagree. You should lap the hone and then chamfer the edges, otherwise all you're doing is squaring off the edges all over again, and increasing the risk of chipping the edges even more.

i usually lap then bevel then a quick lap just to clean off any loose stuff from the beveling. But yes, i see what you mean. I put quite a large radius on the bevel though so few thou's (probably?) of an inch don't bother the bevel too much. i agree with you though in the case of a small radius bevel.

i'm assuming the OP had already lapped his stone once?
