Tomo Nagura Lapping 101

[@Greyswyndir]

Great video Keith, and you're right, I much prefer someone who knows what they're talking about, rather then some parrot talking shit on a shaving forum. That's why I value your opinions and your knowledge on this stuff. You don't just talk about it, you actually do it. This is a great resource, I've learned a lot by watching your videos. Thank you.

I’ve recently ventured into wild, exciting and expensive world of JNATS, and I just have to say that the knowledge shared here is invaluable. Thanks for preventing me beforehand from possibility ruining the surfaces of my JNATS. I’ve just finished lapping my naugras as you showed.

Man I wish I click on more than one LIKE. This video has so much important information that helped me out so much than one can realize and Keith analyzing each raised problem or issue with critical thinking and experience. Thank you so much man.

Hi Keith, thank you for uploading your videos. I find them very educational and resourceful. Your website also has a lot of information and its helped me determine what to buy as i start my journey in resorting straight razors... again thank you for your help. Regards graham

That's what it's all about Daniel, thank you for watching and commenting!

1. Did I understand it correctly that working on sandpaper ~220 makes surface on a nagura that is rough enough for creating slurry on a base stone? 2. Is this technique of creating rough surface on a nagura applicable for base stone? In other words how rough should be the surface of a base stone for good results?

[@KeithVJohnson1]

There are no absolutes. Try stuff, see what works best. I usually finish lap base stones with a worn 400x Atoma. Maybe 600x w/d. It's conceptual, smooth minimizes friction, coarse enhances friction. You have to find balance.

[@sashashkodich9505]

@@KeithVJohnson1 how do you think does the surface roughness of base stone or nagura influence the size of particles in slurry to some extent?

[@KeithVJohnson1]

I find that a finer finish on a base stone minimizes its capability. Coarser finishes don't seem to allow the stone's full capability to be utilized. I use the same diamond plates to lap or surface Nagura. As for particle size, these are Natural stones, there is no 'grit'. Of course you don't want chunks floating in the soup. Think less, hone more. Works better that way.

[@Cdub33]

Keith, maybe a dumb question, but when you show that rocking motion and the getting the slight curve on the naguras, is that the same idea or motion you use when building a slurry on a stone? I assume rubbing a flat Nagura on a flat stone is not ideal / scratches stone as you mentioned?

[@KeithVJohnson1]

Basically the same, yes.

[@jme4786]

9:46 I wish I had so many nagura laying around that I rediscovered ones I didn't know I had in drawers around my house

[@KeithVJohnson1]

happy honing!

[@tayloralbrecht8362]

When you speak of dressing down your stone after the initial flattening, are you dressing it down with any nagura stone?

[@KeithVJohnson1]

It really depends on the stone, and the surface condition, and flatness. Sometimes, yes, I use huge nagura to fix up a stone. Other times, w/d sand paper. Sometimes, both. Occasionally, I use another full sized stone.

[@martinmallory2474]

Are you using the same grit nagura? Example, 8000 grit stone you use 8000 grit nagura? Thanks man. Your videos are amazing. I am going through all of hem lol

[@KeithVJohnson1]

Hi - thank you for watching and commenting. Natural stones can’t be evaluated in terms of grit, same for Nagura. Its a complex subject that I refer to in several vids.

[@martinmallory2474]

@@KeithVJohnson1 i have noton whetstones. 1000,4000,8000, and a naniwa super stone 12k. What would you suggest? The 4,8,and 12k have black dirt like marks after honing. After watching videos of your ive found out that its micro pieces of metal.

[@KeithVJohnson1]

Hi I would suggest honing a lot. That's the only way to learn. The black stuff is called swarf, you'll need to lap the stones flat, keep them flat and keep them clear of swarf. You should probably join my FB group - tomo nagura - most of the members hone often and they can be very helpful.

[@martinmallory2474]

@@KeithVJohnson1 excellent! Thank you tremendously

[@michaelshults7675]

3m is good stuff. Do you prefer SIC or Alum oxide 3m paper?

[@KeithVJohnson1]

The paper I have out on my bench right now is Try-M-Ite by 3m, it's SIC - works fine. Dunno if it works better or worse than something or anything else, I just know that it works well.

[@michaelshults7675]

Keith V. Johnson Yes that's great stuff. Expensive, but worth it. I also like the 3m #213q alum oxide. D

[@KeithVJohnson1]

I guess everything is relative but I don't consider it to be expensive.

[@michaelshults7675]

Keith V. Johnson do you have a good source to buy in bulk?

[@KeithVJohnson1]

I don't buy in bulk - I just get it from the hardware store by my office.
