- Lapping whet stones - the cheap, easy, zero-waste, ecological, simple, DIY method with three self made clinker bricks. Works for Japanese water stones (Naniva, Shapton, Imanishi, Shin Nagura…), hard natural stones (wästikivi…), and even for lapping stones. Complete how to guide.

-----------------------------
- Which brick to choose?
It should be hard enough and suck water as least as possible, better, not at all.
German woodworkers usually choose so called clinker bricks. Unfortunately they are not available every where in the world. I tried with old oven bricks - too soft and too thirsty, new, normal bricks - still too soft and thirsty, chamotte bricks - hard enough but soaking water.
If someone knows other bricks possible to use for this, please share in the comments!
I end up ordering three clinker bricks from Germany.
- Why to start on concrete?
Not necessary, but it might fasten the lapping process. Also the grinding powder is not necessary. For minimalists, just three bricks can do it!
- What is the soap good for?
The foam helps to get the grinding powder to come out of the wholes and keep on working. Our self made hard shampoo makes the best foam.
- How long does it take to get the bricks flat?
About on a afternoon should be enough.
- How often do you flatten your whet stones?
If i am working in my workshop, every time i sharpen, i start by lapping. On construction i usually use my hard natural stones (Wästikivi). They can do longer without getting hollow.
- How did you get this idea?
The idea came from F. Kollenrott. He wrote very detailed guides about sharpening all kinds wood working tools, unfortunately only in german. That is why, i decided to translate one of his methods into a language everyone can watch :-)
- What is Wästikivi?
I'll introduce them in my next video - Zábava
My farther was a carpenter and joiner all his life and he used to put sand on a piece of glass to flatten his sharpening stones here in the uk
Sand or abrasive powder
Tolles Video, vielen Dank dafür!
Ich habe sie mir aus Kanalklinker gemacht, jedoch saugen meine Steine das Wasser auf. Ich nutze sie schon über 10 Jahre und bin immer noch begeistert, dass man mit so einfachen Dingen so viel ausrichten kann!
Interessant, mich hatte das Saugen sehr gestört, aber, Du kommst damit klar. Es gibt so viele Wege zu scharfem Werkzeug. Vielleicht ist es wie in der Natur auch - die Diversität ist es, was die Dinge ausmacht.
I used to put sand on concrete blocks to level my sandstone sharpening stones.
Thank you for this comment :-)
It took me a while to get my corrund powder. Not easy to find in small amounts. In the moment i had it between my fingers i was wondering, if exactly sand would have done it.
May your comment save someone elses time ;-)
3 paltes method! Works as good as ever, I had my granite plates flattened so (took better part of 2 days wit SiC powder). Just have to remember to turn then 90° every now and then to avoid twisting in to propeller.
Just found your channel and Subscribed.
Interesting. I can do with some of them
Это называется выравнивание по методу трех плит, применяется при шабрении поверочных чугунных плит. Но есть один нюанс: плиты должны быть квадратными и в ходе работы поворачиваться на 90 градусов, пока не получится 360 градусов. Иначе не получить ровной поверхности.
Awesome

I'm curious, with the availability of so many diamond stones, why do you continue to use natural stones?
Following, I'm interested too
Good question :-)
Diamond stones - well, they might perform very well, but something holds me back.
Maybe, it is bit like choosing hand-tools instead of machines. In natural stones (or artisanal made water stones) i easier find a soul i can connect.
If you are interested, i have in mind showing my new natural stones and how they perform in near future. I admit not having much experience with diamonds but am confident, that my tools get at least as sharp ;-)
OK, I understand your thoughts on this and I appreciate your response. Thanks for the videos.
To my experience the coarse diamonds might perform well, but when it comes to finer grids, specially polishing, traditional water stones or some natural stones are much better.
Another point i prefer in water or natural stones is, that they keep the same quality from the first stroke to the last.
Interesting question!
To my experience the performance of the finer traditional water or natural stones has not been reached with diamonds, specially, when it comes to polishing.
Another point i prefer in these stones is the fact, that they keep their quality from the first stroke to the last. The quality of diamond stones continuosly decreases during their lifetime.
I have only one very coarse diamond left, i only use to flatten my water and nature stones.
Wow. What a sun raise, set? How much time you have with sun light during a day now?
I'm not sure if that's a sunset or a sunrise, but a nacreous cloud. Quite common in colder climates, but we actually had them here in Scotland yesterday. I had never seen them before, so had to search the internet to find out what they were.
Yes, well seen. Here, we call them helmiäispilvit - pearl clouds. It was a beautiful evening.
Today, there is no sunlight here, it's cloudy ;-) It would be about 3-4 hours. And from today on, days are getting longer..
Could I use natural sand instead of the powder? edit: Read through some of the comments, and at least according to them, it should! I'll try it
--> Yes, should work just perfectly. But very important, to choose the right bricks - klinkkeritiili.
