Thread: Getting a Naniwa 12k

and wondering what I should get to lap it with. I don't have any real interest in restoring blades, just resharpening the one that I have (for the time being anyways). I know the DMT's are supposed to be good, but if someone would be kind enough to point me to the right one, I would really appreciate it!

Thanks guys.

Sounds good. Would a hone mount be worthwhile as well, or no?

If you mean the adjustable stand for about $15.00 I like them and have one on my DMT. Lays in the bottom of the sink while the water trickles down and washes the swarf away. More convenient than if I was having to hold it in the opposite hand.

I prefer the DMTXXC does everything else the DMT C does only faster.

It sure does and I am glad to have one. OTOH, it really leaves a rough surface on the hone and my usual routine when I do use it is to follow with the 325 to clean up the scratches and roughness. Some guys I know follow that with 600 and then 1000 grit sandpaper on fine finishers. I keep saying I'm going to try that but haven't so far. The 325 seems to be good enough.

My Naniwa 220 grit lapping plate works great on the Naniwa 12K.

For what it is worth, I do not worry about some scratches. On the
8K side of my Norton I watch the surface and as long as I can see
the scratches all I do is wipe the surface with the palm of my hand
to remove accumulations of swarf. I do this because I know that
the scratches are shallow and as long as they persist I have not
worn my hone to a point that it needs to be lapped. I do the same
with my Na12K SupertStone.

Years ago I ground a telescope mirror. In the polishing stages
we would polish on a lap of pitch that had channels cut in the surface
so swarf and water could move. One of the novel laps was bees wax
foundation used by beekeepers to invite bees to build comb in
the right place. The hexagonal impressions held water and a decanted
suspension of red polishing rouge
