Precision ground FLAT STONES - Home Shop

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

[@wbryantclark]

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.

[@asbcustom]

Thanks to the selfless and tireless work of the KZbin 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.

[@bradthayer6782]

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

[@tableshaper4076]

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.

[@kevinfaulkner8801]

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.

[@CraigsWorkshop]

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.

[@OstapHelDesigns]

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!

[@ROBRENZ]

Very nicely done! subscribed. ATB, Robin

ROBRENZ thanks uncle Robin

[@xenonram]

Wow, an endorsement from the man himself. Impressive.

[@jeffo881]

No pressure

[@davesmith9325]

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

[@mumblbeebee6546]

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

[@TheRadioShop]

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

[@arnljotseem8794]

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

[@msquared6324]

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

[@nectouxpierre4634]

Bravo, I really love the wheel dresser! Nice video

[@bostedtap8399]

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

[@craigtate5930]

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

[@magnumpunch]

So modest as well.

[@rickpalechuk4411]

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

Yeah. It's true

[@mumblbeebee6546]

Cà Lem If it's true, then I offer congratulations! (I could not resist that...)

[@artmckay6704]

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

[@stanstevens3783]

You are very resourceful and show a wide range of skills

[@jawadibrahim2367]

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

[@VastCNC]

Your shots and camera work are top notch!

[@rgmoore]

Another great video. You make it look so easy.

[@douglasharley2440]

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

[@TwohandsStruggler]

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 .

[@RutherfordRyan1]

Or you could say “ Twice “

[@irfanashraf1238]

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

[@Self_Evident]

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... :)

[@richardhead8264]

_Cà Lem Excellent craftsmanship and demonstrations!!_

[@rodneykiemele4721]

Great wheel dresser, Thanks

[@stevecanny1583]

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

[@forrestgumpv9049]

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

[@DK-vx1zc]

Very interesting! Thanks for sharing.

[@peteroleary9447]

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.

[@zephyrold2478]

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.

[@peteroleary9447]

@ You seem to be getting your hands on many things and learning by doing. This way was impossible until KZbin. 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.

[@werschkowdennis6533]

Very good Work. Bravo Maestro. 👍

[@brucekoehler276]

wonderful work

[@BurtonsAttic]

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.

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

[@DuncanAitken]

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.

[@theprojectproject01]

That is really, really inspired.

[@senseyZ]

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.

[@glennmoreland6457]

Superb...🇬🇧👍

Cool tattoos 😁😁😁👊👍👍

[@russellhayward2359]

Excellent work. 😁

Thank you!

[@russellhayward2359]

@ all of your videos are excellent. Having the surface grinder will just add another element to the work you can produce.

[@TomMakeHere]

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

TommyGun Machining oh yeah. Test your SG as well

[@TomMakeHere]

@ I'll have to copy your grinding jig, that is a great idea

[@MrHien38]

Amazing

[@jeffanderson1653]

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

[@yazanalfaourgaming8555]

Amazing 😉

You first ;)

[@jeanloreaud9282]

Joli travail bravo à bientôt salut Jeannot 🛠😉

[@liquerinfrnt]

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.

[@samrodian919]

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.

[@Just1GuyMetalworks]

Cool! Don't see that everyday! 👍😊👍

[@Ryan-lz8zm]

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

[@Turco70]

nice orchids

[@xConundrumx]

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 ;)

[@xConundrumx]

Cà Lem build one!

[@roxter299roxter7]

You obviously see the beauty in precision

[@flatsurfaces1913]

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

[@454Casull]

just one person here yes, that’s what it says

[@greybeard3759]

Truly enjoy your videos! Are you trained as an engineer? Also love that grinder...want to sell it? ;o)

[@40nmugzy]

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

[@rsemrad2]

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. 👍

[@greasydot]

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

[@jeffanderson1653]

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.

[@samrodian919]

I too have Mexican made Norton orange and brown stones and even as bought they're not too bad

[@maximpozdnyshev2013]

Nice! Greetings from Russia for good work!

[@carllie4848]

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

[@thaipham9786]

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

[@lohikarhu734]

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?

[@rizalardiansyah4486]

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

[@sinadaneshkhah8537]

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

[@bhnjhbjhbkgkkvhnhmbm]

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

[@danl.4743]

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

[@lmsaltest]

Great job! What surface grinder is that?

[@xenonram]

He's got an entire video on it. It's amazing.

[@jessemendes9491]

Perfeito !

[@Imba-gt7qi]

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.

[@vinkl25]

We make grinding stones like that in the company where I work.

[@TomChame]

Very neat!

[@IslandHermit]

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

[@jrod4538]

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

[@chuckphilpot7756]

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.. KZbin 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.

[@James-fs4rn]

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

You're in a class by yourself.

[@ExtantFrodo2]

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

[@xenonram]

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.

That alone was enough to demonstrate their flatness. The dimple was superfluous.
