- Couldn't find these stones here so i decided to make some of them ;)
As always, Thanks for watching and thanks for your support: / calem21
Here's Mr. Robrenz video: • PRECISION GROUND TOOLR...
GO check his other videos. He won't disappoint you, i promise.
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 😃
wbryantclark thank you.
Thanks to the selfless and tireless work of the TH-cam 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.
Very nicely done! subscribed.
ATB, Robin
ROBRENZ thanks uncle Robin
Wow, an endorsement from the man himself. Impressive.
No pressure
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.
You accomplish miracles using only normal tools. This is the sign of a MASTER craftsman. Great respect !
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.
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!
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.
Those stones will most likely be better than the ones you purchased. Great job!
Great work. Making all the tools as you go, you're not shying away from a challenge
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 second that.
Peter O'Leary I didnt even know that we can dress the diamond wheel since last week. Just a quick and dirty build to make a job done. Also messed around with surface grinder. First time got my hands on it. Thank you for this informations.
@ You seem to be getting your hands on many things and learning by doing. This way was impossible until TH-cam. You would either have had to figure it all out yourself or worked for a company as an apprentice. There is very little organized literature for these trades. I congratulate you for seeking out and finding good information (ex. robrenz) and putting it to good use. I wish you success for your future. You seem to be having fun doing it.
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.*
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 .
Or you could say “ Twice “
Very cool! Nice innovation with the discarded grinding wheel. Nice work all around 👍👌
Bravo, I really love the wheel dresser! Nice video
You are very resourceful and show a wide range of skills
Testing the stones after grinding, that's the challenge.
Thanks for sharing,
Cheers
Yeah. It's true
Cà Lem If it's true, then I offer congratulations! (I could not resist that...)
I literally just thought about getting stones out of a bad grinding wheel a few days ago...great minds think alike. Nice video
So modest as well.
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.
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... :)
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. ))
_Cà Lem Excellent craftsmanship and demonstrations!!_
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 !
Your shots and camera work are top notch!
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.
The moment I saw feather board clamps I gave you 👍🏼 and a subscription
Excellent, CBN wheel dresser works well.
Thanks for sharing and best regards from the UK.
Very Nice and Very Clever !!! Thank you !!!
nice work!
Flat stones are definitely a must have in every shop!
Kudos! :)
Grate job my friend glad to see your doing well. Keep up the good work
Thank you!
Where do you live if i may ask
@@josephlovell6951 he is from Vietnam
Thank you for that information
I hope viruses for China does not make it there the thought of you geting sick would be bad. I am very impressed with your improvement as a machinest
great work! you make it look easy!
Thanks! just a piece of cake for you, man.
Love the clamp technique
that was beautiful, nice work making that dressing tool too.
Another great video. You make it look so easy.
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.
It was also amazing to see how far the centre punch mark actually deforms the surface. After stoning you could see a big ring of flattened steel around the dot mark.
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.
That is really, really inspired.
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
nicholas marzigliano thank you. Maybe next video
Exellent. Thanks for sharing.
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.
👍
You obviously see the beauty in precision
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.
Great wheel dresser, Thanks
Estupendo trabajo. Un saludo desde España
Beautiful job on the brake dresser Cà Lem! I've got to make myself one of those :)
Nice! Greetings from Russia for good work!
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!
If i had money i would buy a damn aircraft and fly around the world ;)
Cà Lem build one!
Nice work Cá Lem.
Very interesting! Thanks for sharing.
pretty good use for a bad wheel. most people throw them away
Good job man
Very good Work. Bravo Maestro. 👍
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
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
Nice Job!
Steve
very fancy flood coolant system you have there at 9:30 ;-)
Flat! Man it's still really cold here, nice to see your garden!
Thank you uncle John. Maybe next time i'll show the rest of it. my shop is tiny but my garden is a real football stadium.
Hello.
Always look at your videos. Thanks.
But I Wonder witch type of grit is it on these Stones?
I don't even know what these stones are for but I watch it till the end anyway lol
Thanks again
Great job
I see you watched robin renzeti’s video on how to make precision ground flat stones.
just one person here yes, that’s what it says
Cool! Don't see that everyday! 👍😊👍
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
Joli travail bravo à bientôt salut Jeannot 🛠😉
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.
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.
I too have Mexican made Norton orange and brown stones and even as bought they're not too bad
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.
👍 nicely done! Where did you learn so much of the trade? Did you have a school or mentor?
Nice job!
Tool maker tricks 👍👍
Don’t give away too many of these 😂😂
JROD What kind of backward ass logic does that amount to? So fuck all the next generations? Are you an idiot? I am going into toolmaking currently after having been a mechanic, a machinist as well as a swiss machinist as well as heavy fabrication, stamping, drawing, pilger milling, welding, electrical, circuit layout and diagramming, pneumatic, and hydraulic systems. and most anything else you could think of.. TH-cam is the #1 source of information(Aside from the exponentially decreasing rate of even availability of traditional apprenticeships) in days where Toolmaking is a trade that is dying by the day. Hopefully You are just ignorant and not outright purposely deceptive. Holding someone else's life back because you want a little power (information) over them is quite honestly the most petty thing you could possibly choose to do with your pitiful existence. You got a brain, roughly between the time you were conceived and when you were born if I am not mistaken lol. You should try using to think about more than just yourself for once.
Gerçekten akıllı bir adamsın. That's how we say "You are really a wise man" in Turkish.
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 ;-)!!!
Very Gooddd....!!! My friend...ji ji ji
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?
Nice! Thank you.
Very nice work!
These are also on my to do list
TommyGun Machining oh yeah. Test your SG as well
@ I'll have to copy your grinding jig, that is a great idea
Nice Work Ca....Enjoyed 👍
The Ayr Cave Shop thank you
I've heard Soviet/Russian diamond/CBN wheels are quite good.
6:02 "China again" lol
Hate to admit it, but this nasty monster [China], is one we built ourselves; starting from the top on down.
@@DanKoning777 What do you mean by "we"?
@@fulljackrackoboe // Congratulations for being the only one who has never purchased anything made in China; or did my comment go over your head?
@@DanKoning777 Are you a fortune teller or it's just your ego that makes you write that crap? Because I haven't said anything yet, you´ve made it all up yourself. The only thing that went over my head is your rudeness and your petulance . Do not speak on behalf of the rest of the world's population, perhaps there are some people who thinks and acts in a different way as you do. Don't come out of the blue bothering other people and don't pretend to know everything. This is about companies no about individuals, doesn´t matter if you or me or our friends buy a few stuff in fucking China or made in China, it will not make much of a difference. Or do you think they are that big because of our purchasings? All that greed from the companies has made this happen. 20 years ago I said that was gonna happen and booom here you have it. I´ve been always against buying Chines stuff and I'm not buying Chinese stuff as much as I can but it is obvious that nowadays is almost impossible as everybody knows. And NO, not all of us have build this monster.
@@fulljackrackoboe // Truth is a stubborn thing; isn't it? Have a nice day.
Amazing 😉
You first ;)
What did you need to dimple that block for? The stones brought out the ripples of the grinding process. Fantastic!
The point of precision ground flat stones is to remove dings and dents from machines surfaces without being able to remove any of the flat surface of the material. (Like indicator bases, to get any burrs or upset areas out of a house and mill table before you put the vise back on, after doing a scraping pass to get all the burrs flat before you blue it again, or any flat machined surface.) You rub it on any flat machined surface that is going to interface with another flat surface in case it got and dents while it was in storage, being transported, or while being handled. When you rub the stone on a flat machined surface, you can feel/hear any areas that are upset, and you can hear/feel when they become flat again. He center punched it so that it would raise/upset an area to show off how the stones work. The stone will flatten the upset areas, and make the surface flat again. The benefit is that, once the upset area is flattened, no matter how long you continue to run the stone over the surface, it won't take any more material off. It polished the high spots in the chatter (ripples) from the surface grinder. That's why they're more visible. Even though the amplitude of those chatter undulations is probably only on the order of "half tenths" (50 millionths or 0.000050") from peak to trough, the stones still knocked enough of the peaks off, to polish them enough, to make them more visible.

Isn't that what I said? That alone was enough to demonstrate their flatness. The dimple was superfluous.
wonderful work
Hi my friend. Hehe.
Khoẻ ko bác. hết Corona chưa
May quá k sao. Hehe. Vẫn khỏe để xem video DIY.
We make grinding stones like that in the company where I work.
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.
Seems like your "brake"dresser is using only bearing preloads...are they not centrifugaly braked as they should be?...
Cool tattoos 😁😁😁👊👍👍
Seems like just using 3 like for creating surface plates would be the better route.
Nice flat !!
The green paint on the mill looks awesome, what color is it? Do you ave a name or number?
Great work buddy.
thanks buddy!
Won't the coolant be absorbed into the stone and cause it to swell?
nice orchids
You should try lapping or scraping
Amazing
You have amazing talent. What is the brand name of the cutoff wheels for your angle grinder.
