Should I lap my 1k before use?

Like the title says should I lap my Naniwa traditional 1k stone before I use it?

It seems pretty flat but I need to know if I should lap it before I use it for the first time.

Thanks

Yes.
You can use either a DMT8C plate ,an atoma 400 plate.

Or buy a flat granite tile and some 200 grit silicone carbide loose grit from a sandblasting supply store or online (ebay amazon)
Or even use 200 to 300 grit wet&dry sandpaper on a very flat surface. ...flatness is important !

If you use a tile be certain to check the side you are planning on using with a straight edge to get a flat lapping surface!

You can also go to Walmart and buy a glass cutting board and use that for the sandpaper or silicone carbide loose grit. ..

Cool I have some 220 grit and 600 grit. I'll try the 600

Or will this DMT plate work?

How long is that dmt? Is it equal in length to your stones? If yes or nearly so then I would try it out.

It's about 2 inches shorter length and 1 inch shorter width.

Well I ended up lapping one side of my stone Yesterday.
I used 600 grit sandpaper first but it was taking to long so I used 220 grit. I drew a grid on it with a pencil and stuck the piece of sandpaper on top of my granite top in my bathroom.
I hope it's flat enough I'm gonna go soak it and and set a bevel on a blade soon.

I highly recommend lapping your stones to ensure true flat, especially if you are new to honing. Minimizing the number of variables makes it easier to learn. As your technique gets better you can compensate for more of the odd stuff
