Precision ground FLAT STONES - Home Shop 

As you continue to try new things and grow your skills it is a joy to see you succeed. Many people look at machining only as a means of production. But they fail to understand the process of machining is an artistic and problem solving exercise. Thank you for taking the time to share your efforts. Charles

Cà Lem, I just can't get enough of watching you refurbish old and neglected machines back into service. Your humble, yet impressive approach is very inspiring. I love the hanging garden too. I'm looking forward to the next addition to your shop. Another refurbished machine, or a new fabricated idea always brings me back to watch with joy and leaves me with a good feeling that there is more to come. Thank you sir. As always... well done 😃

Thanks to the selfless and tireless work of the RU-vid machining community, I expect to see a world-wide Rennaissance of the trade among the "doers". Thank you everyone, and Robyn in particular, you are a humble, masterful, and inspirational instructor.

Love your garden! And you are doing a wonderful job building a full-featured shop.

I loved seeing the magnet powered steel clamps - very ingenious. Great that you can now make precision flat stones. I am saving up for a set.

Nice use of the tool makers clamp! I had not thought of that. Again, nicely done. I guess I am going to need to start looking for a good used surface grinder. Thanks.

Precision ground stone is my great discovery of 2019 due too Robinrenz and Stefan Gotteswinter videos 😊you will use them everyday for almost everything! Well done and greetings from Poland!

You accomplish miracles using only normal tools. This is the sign of a MASTER craftsman. Great respect !

Great work. Making all the tools as you go, you're not shying away from a challenge

As a woodworker I was thinking, he's making feather boards, what the hell for! My feather boards turned out to be very clever grinding stone hold downs, great job.

Those stones will most likely be better than the ones you purchased. Great job!

I admire your work and respect your skills already, now I also adore your hanging garden! :)

11:03 not only is your machining beautiful, your gardening is too! *respect.*

Very nicely done! subscribed. ATB, Robin

Great to see that there are people who lover their machine's and keep on improving them. And when you buy cheap stuff you most likely are buying two times xD .

You are very resourceful and show a wide range of skills

Testing the stones after grinding, that's the challenge. Thanks for sharing, Cheers

Mr. Cà Lem is a very resourceful young man. He fabricates a brake dresser and magnetic finger holddowns - amazing! A brake dresser usually uses as crystolon (silicon carbide) grit wheel. This type of dresser has a rotor with pads that expand centrifugally inside a housing, providing some resistance to free spinning at the speed of the diamond wheel. I prefer a motorized dresser. If equipped with a speed control it is more efficient and helps keep the diamond wheel flatter and without rolled-off corners. Still, awesome job. He is to be supported and encouraged in all ways.

I literally just thought about getting stones out of a bad grinding wheel a few days ago...great minds think alike. Nice video

Beautiful Cá Lem, is beautiful what you do, is beautiful the way you show the beauty of it. keep it up, you are a true artist, you have a serious mojo going on there, you will fly high. ))

Very cool! Nice innovation with the discarded grinding wheel. Nice work all around 👍👌

_Cà Lem Excellent craftsmanship and demonstrations!!_

Awesome video! I also like the Schaublin rebuild. All of them very inspiring! But, I have to say, I'm now torn between wanting to get off my ass to try to accomplish/go do something like that myself, and wanting to stay sitting here watching the rest of your videos... :)

You obviously see the beauty in precision

An awful lot communicated with a single word of dialog. Very nice.

Great idea and good job on the video. Machinist 40+ yrs, have not seen that one !

The moment I saw feather board clamps I gave you 👍🏼 and a subscription

Another genius with the angle grinder. No guard. No side handle. No 2 points of contact. No heavy leather gloves for protection. No eye or face protection. Just brilliant.

Very Nice and Very Clever !!! Thank you !!!

Bravo, I really love the wheel dresser! Nice video

Your shots and camera work are top notch!

Grate job my friend glad to see your doing well. Keep up the good work

nice work! Flat stones are definitely a must have in every shop! Kudos! :)

Excellent, CBN wheel dresser works well. Thanks for sharing and best regards from the UK.

that was beautiful, nice work making that dressing tool too.

That was neat how you could see the chatter from the grinder after you stoned the part at the end. Shows you how many levels there are to a precision flat surface.

ui. lần đầu tiên thấy được 1 kênh Việt Nam về kĩ thuật có độ chuyên nghiệp không kém 1 kênh nước ngoài nào. cảm ơn a đã cho ra những video chất lượng thế này. xưởng a có đầy đủ máy mài phẳng bàn Map ùi luôn. không biết a có kênh facebook không ạ

Dude ... if I had money I would fly you over to my country and start a damn business with you! You are too damned talented!

Another great video. You make it look so easy.

Love the clamp technique

At 5:00 the grinder sounds like it is loading up. Is it because you spray cool rather than flood cool? What is your feed rate? 6:15 I really like your spring clamps to tighten and apply downward clamping pressure. I prefer that to precision vice. 👍

great work! you make it look easy!

Nice I like your channel. I’d like to hear you talking. Practice makes perfect. Don’t worry we think it’s cool to watch your videos from the other side of our planet. I had my granddaughter watchind

Flat! Man it's still really cold here, nice to see your garden!

Bravo! wonderful work, as always. It's great to see that the time you invested into restoring your machines is starting to pay dividends. Thanks for the insight into how, and why, you go about flattening the stones. Very clever with the spring steel too.

Great video, I literally laughed out loud when I saw you cutting that grinding disc As I did thd exact same thing few days ago! Robrenz has not addressed the problem of useless "combination stones" at all. I can see you've discovered it very quickly with your "Chinese stone". Those currently popular bench stones (not just Chinese, also German and many other) are way too soft to be used as a precision ground stone. You can't rub them together because they grind each other down despite being dull on top of the grains... I wish you mentioned something about it in your video, but I understand not wanting to contradict "established masters" who erroneously say "take any combination bench stone and grind it". That's not how it works. The stone has to be at least K hardness (preferably L). The smaller the grit the more important it is that the bond is hard. All those crappy "waterstones", "heystones", "kenzo stones", "Japanese sharpening stones" are all TOO SOFT. But WHY? Why coul a person walk into any hardware shop in the world 30 years ago and buy a hard stone for small change, and suddenly now ALL SHARPENING STONES ARE SOFT! I have a theory. I believe it is because of the popularity of Japanese blades and knifes. Everyone considers Japanese steel as (rightfully) good, and their knives too, so a random person thought if they have great knives they must be masters in sharpening them, right? But this is soo wrong. In Japan, there is no naturally occurring hard abrasives, only fairly soft ones. So over centuries Japanese made the best with the crappy abrasives they had at their disposal and they've managed to come up with excellent blades despite it's shortcomings. Unfortunately, because the traditional Japanese method used very soft abrasives and it was traditional it must have been good, right? All the European (less in America) traditional stones were thrown out and every shop now sells those pityful soft things. A brick is harder than some of them! The other day I bought another (new brand, one can hope, 240 grit) and when starting to grind I was marking it with a pencil. The pencil had dug into the stone where I pressed harder.... So Ca Lem, Thank you for showing how you're cutting that grinding wheel to make your stones, at least you illustrated the problem.

Brake Dress!! I'm making one. I was trying to figure out how I was going to get the flat spots, facets, out of the Shars, diamond wheel. Thank you

Exellent. Thanks for sharing.

Nice tecnic, but remember, wenn your grindstone ist bigger than the Metal, you grind at the edge of the metal first (handgrinding)! even both are perfect flat, best way is to get two stones, one bigger, one smaller. with the smal you grind more in the center.

You have inspired me to grind some smaller stones. I have already ground the 2x6 Norton orange and brown (made in Mexico = good or bad?) They are used all the time in my shop. Well done, as always, I look forward to your videos.

Hello. Always look at your videos. Thanks. But I Wonder witch type of grit is it on these Stones?

👍 nicely done! Where did you learn so much of the trade? Did you have a school or mentor?

Always buy 3 stones. Grind A against B, then B against C, then C against A. You gotta bash the rocks together. This pattern done in just a few strokes in each combination over and over will produce a more flat stone than the process in this video. Wheels make wavy surfaces. We've known this trick for close on 8,000 years.

Nice Job! Steve

Nice! Greetings from Russia for good work!

I see you watched robin renzeti’s video on how to make precision ground flat stones.

Beautiful job on the brake dresser Cà Lem! I've got to make myself one of those :)

Estupendo trabajo. Un saludo desde España

Nice work Cá Lem.

Hello Thank you for your helpful video. Ihave one qoetion please give response if it’s possible. Why when igrinded my stone white diamond wheel is not sharp like before? Also is exactly flat surface but isn’t sharp like before

What did you need to dimple that block for? The stones brought out the ripples of the grinding process. Fantastic!

very fancy flood coolant system you have there at 9:30 ;-)

Cool! Don't see that everyday! 👍😊👍

Tool maker tricks 👍👍 Don’t give away too many of these 😂😂

Thank you for the video, great, I can't find-what kind of stones do you use and what is their grain? Thank you in advance.

I don't even know what these stones are for but I watch it till the end anyway lol

Very good Work. Bravo Maestro. 👍

Great wheel dresser, Thanks

Very nice work! These are also on my to do list

I'm just a beginner...is it so that the dressing stone is at a very small angle to the diamond wheel, so that it rotates 'across' the diamond wheel, a bit, and spins at a much lower speed than the diamond wheel?

Very interesting! Thanks for sharing.

Won't the coolant be absorbed into the stone and cause it to swell?

Seems like your "brake"dresser is using only bearing preloads...are they not centrifugaly braked as they should be?...

I really like the was how you made this really nice pieces of soap bars for the tough men among us, to scrub all the dirt after a long day in the workshop. These bars of soap should last a long time and will get your body perfectly clean ;-)!!!

May I ask you how old you are?

Gerçekten akıllı bir adamsın. That's how we say "You are really a wise man" in Turkish.

Good job man

I've heard Soviet/Russian diamond/CBN wheels are quite good.

What is the fluid you're using at 10:00 to wet the stone? Is it a regular coolant?

Nice Work Ca....Enjoyed 👍

The green paint on the mill looks awesome, what color is it? Do you ave a name or number?

Nice job!

Great job

You have amazing talent. What is the brand name of the cutoff wheels for your angle grinder.

pretty good use for a bad wheel. most people throw them away

Joli travail bravo à bientôt salut Jeannot 🛠😉

Whats a good grit to start with? (for the stones)

Wouldn’t it be better to have 3 stones to rub against each other? How could you tell if one stone was convex and the other concave?

Hi my friend. Hehe.

Стекло + карбид кремния + вода = ровный камень. Керамогранитная плитка + карбид кремния + вода = ровный камень. Вместо карбида кремния можно использовать просеянный песок. Ровно тот же эффект но чуть дольше.

Thanks again

Very Gooddd....!!! My friend...ji ji ji

Great work buddy.

Excellent work. 😁

wonderful work

12:11 you killed my soul, that cruel and heartbreaking

Seems like just using 3 like for creating surface plates would be the better route.

i guess your camera is GH5, because the focus is all over the place

Nice! Thank you.

Nice flat !!
