A balance washer can improve wheel imbalance. Make the washer about 3mm thick, and 70-80mm in diameter. Drill the shaft hole 1-2mm off center. Mark the wheel and washer. Try the washer rotated in various directions until the imbalance is gone.

Well done. All grinders should come from the factory like that.

Friends, if you don't have Somafix, use epoxy glue, it's even stronger. Epoxy gets into the pores of the abrasive disc and it's a stranglehold. They write to me here in the comments that it will fly off and gouge out the eye. They did not see and did not try to tear off Somafix, especially from a rough surface. Yes, I needed to show epoxy bonding, but I was sorry for the time, I'm sorry. I do not recommend any other glue except for CA Somafix and epoxy, it can really be dangerous.

Doskonale wykonana robota, której się nikomu innemu nie będzie chciało wykonać.

I just learned about two years of metalwork class in one video. I am reasonably smart, done a bit of metalwork, and know a few things. Its been a long while since I sat down and watched a video that school me. Excellent work.

Thank you very much for this video. I will have to try this out on my bench grinder, which has really bad vibration, like yours at the beginning! I was not aware of the reasons for the vibrations and how it can be fixed. I thought it was just a „not so good quality machine“ and I had to live with it. You have shown that this is not the case and how it can be improved a lot. 👍

This must be the *best* video on bench grinders on YT. Awesome work!

Damn, I love the Russians! Every technical detail and sheer artistry of wheel balancing covered. Like everything they do, it is first class. Art, Mathematics, Physics, Space Flights, Lacquer Paintings of Fedoskina and Palekh, the Hermitage treasures, the Kremlin treasures, Rostov Finift, their gymnasts, the Bolshoi Ballet, Chekov, Pushkin, Dostoyevsky, the music of Prokofiev, Tchaikovsky, Rachmaninoff ... such an incredible drive for excellence. Keep up the good work. Subscribed. Greetings from California! Dying to visit Moskva and Sankt Peterburg again. Thank you! Большое спасибо!

Always a great idea to have any spinning power tool balanced. I have a buffing grinder as well and with any buffing disk it walks all over the floor with the pedestal stand. I have yet to go through it and balance everything... Thumbs Up!

Real good information. We all learn from this one and it's well, worth knowing and applying.

Thanks for a good video. Didn't know these grinders to have such problems and can be further adjusted.

I had the same problem, I solved it a little differently. Corrected the motor shaft with a lathe and made an adapter flange for the inside and outside. High quality disc used.

Good video. Covers things most home users don't know.

WHAT A GREAT VIDEO... Sir, you must have been a GREAT ENGINEER!!! I'm in COMPLETE AGREEMENT. That Makita grinder is available in my country (Mexico), but all of them are unbalanced, misaligned and lack Variable Speed (needed for slower speeds for some materials) THANKS SO MUCH for all the content of this video. As we do not have any grinder sold here that comes with solid washers or flanges, I will wait for your next video on how to solve the problem without a turner or having to use a lathe. Meanwhile, you have my full admiration and professional respect. Cheers from Mexico!

This is a great video. I've seen some crazy videos with people drilling holes in wheelss and other really dangerous stuff. I've just bought a really nice Jones and Shipman wheel balancing jig at auction for next to nothing and will use your technique to sort my horrible wheels

Everything is fine. To simplify the actions, I can recommend Elitech CT 300. It has ready-made, fairly accurate mandrels that fully correspond to the drawing given in the video. Not an advertisement. And yes, when working metal with a drill at speed, safety glasses are strictly recommended. To avoid! My apologies for the crooked Google translation.

Excellent video . Well done indicating the use of card washers on the flanges .

Your balancing method is a great way to lose an eye , or a lot worse !!!

This is a wonderful video. I have exactly this problem too. A little tip for balancing: According to gravity and when the grinding wheel is stationary, the heaviest point is always at the bottom. Do not drill deep into the grinding wheel with a few radial holes with a masonry drill. This also helps with balancing.😃

Good wrench is the half of the work! Thank You very much for share this great experience. There is very helpfull to understand the troubles.👍❤

Gracias por el excelente video, muy didáctico y práctico. Nos muestra la importancia de tener un disco bien balanceado tanto para realizar un buen afilado de las herramientas, duración de los rodamientos como la seguridad personal pues una piedra desbalanceada nos puede arrebatar la herramienta. Gracias

Thank you greatly. Now I am back on the right path with my old faithful. Thor, the best bench grinder in the world is no longer vibrating. :-)

Has to be the best video I have seen. Great advice and result, thanks for sharing. :-)

I love it when a plan comes together!💪😜

Great job.. really learned a lot here

Thank you so much. It is enlightening indeed. Was never aware of the need to correct the imbalances.

PERFEKT ! ! ! THANK YOU. 1 * Slovakia.

It's a super video. Thanks for your effort. I also do scissors sharpening, I have 4 of the same machine. We have done similar works, but there are also some things I learned from you. Thank you so much.

Brilliant technic & perfectly executed, thanks for sharing.

Spot on realy enjoyed that video subscribed

très bien expliqué et de plus ont n'en apprend tous les jours

Прекрасное видео. From Russia with love.

i have an extra one, a small one that i use occasionally for carbide bits; it is not bolted down, and if i don't hold it down, it goes all over the floor; and it scares me, so that i keep turning it off and on to keep the speed low, afraid one disk will explode!!! i will check it tomorrow as per your video; i may also try a 80mm washer in which i can remove (drill or grind off) chunks at the perimeter,marking the wheel and said washer, not a perfect way, but may improve some; *Thanks for your time, just great*

Vyzera to jednoducho, ale najst spravne množstvo proti zavažia nieje tak jednoduche. Mne to trvalo tridsat minut.

I've been looking for this for a long time, thank you!

When I finish sorting my socks ,brushing the dogs teeth and washing my goldfish, I will do this right away.

The metal weight should be a ring around the shaft, so it can't fly into your face. Otherwise, awesome tips!

The plastic bushings for the grinder wheels are junk. Metal ones are available, and are far more accurate. I do dress the sides of the wheels to true them up as well. Any stamped washer is also junk, but finding machined washers is not easy. You can also buy CBN wheels which come spin and bubble balanced, and last far more longer than standard wheels. They are not made for grinding carbon steels though, only hardened metals.

Bravó,ezt nagyon jól csináltad!👍🕊

damn this man seems to know his stuff

Thanks Grain for you ideas. Starting with a proper face washer and bushing. Only thing I do not like is the glued balance weight. We got to imagine that it COULD come off! How about drilling some weight out on the heavy side? Will this weaken the grinding wheel? Another thing, not to simply press the dresser against the wheel, but hold it firmly against the tool rest so it's only cutting on the high part of the circumference. Even better - I think - I got a cheap single-point diamond dresser and am making an adjustable holder for this to slide across the edge of the tool rest. See Mr Pete #798 and #799. Overall it is a lengthy job to get a vibration-free grinder starting even with a quality machine. Everyone, please be careful!

Thank you for the detailed guide. I bought an expensive brand grinder especially to not have these issues, but that didn't help, unfortunately I have to do all the things shown in the video. but at least i know how to do it.

Ilmu sangat luar biasa saya akan mencobanya

Not listening to a computerized "voice" when this just as easily be narrated by a real human

Thank you Sir.🎉

My 1HP Rikon grinder came with a milled cast iron faceplate

Espectacular video muchas gracias y saludos desde Argentina

This is a very informative video. I have same problem to. Now I can resolve this issue.

Hi folks. Fitting grinding wheels in industry is treated as a highly killed operation reserved to specialist trained fitters. There's a good reason for that. Don't mess with cheap grinders, buy a quality product. Yes, it's more expensive. Much nicer to use and much safer. Incidentally, those paper washers are important, do not leave them out. Check the wheel for cracks before fitting, a light tap with a small hammer and it should ring like a bell, if not, break it and dispose of it. Do not stand in the line of fire. Buy a machine with heavy duty guards and tool rests. Do not grind on the side of the wheel. Have a good read up about 'Grinding wheel safety' before ever using one. Wear safety glasses. Misused these things can kill and blind. The surface speed of a hobby grinding wheel can approach 60 mph, around 100 kph.

Amazing work Dude, thanks for sharing.

Brilliant video once again. Thankyou

Maestro, excelentes analisis de mecánica....sus enseñanzas muy valiosas...gracias.... abundancia, prosperidad, salud, alegría, armonía...para ud y su familia...hare krishna

Excellent, thank you .👍

very smart and optionally, you will save your bearings too 🤓👍

Thanks for sharing

Молодец! Всё подробно рассказано.

по мере изнашивания диска его надо опять балансировать? отковырять грузик и приклеить новый???

I was impressed with this video and have book marked it for future use. You have earnt yourself a like and another subscriber. Good luck with your channel and I look forward to following you to future enlightenment. Thank you kindly.

Very, very good. TNX

I machined pressed on flanges and adaptors for the wheels then made machined balancing washers and thought it was all great. Then the wheels wore after some time and became unbalanced. Too much of a hassle the wheels had a lot of life left. I put on a machined cbn and a diamond wheel. The machined washers I had made were still needed to prevent side to side wobble ( I held +-.04mm at the periphery of an 8” wheel) and radially fit the shafts with no perceptible play or skipping while cutting. All in all setup was 10x less than abrasive wheels and they cut faster. I can’t be making stuff to make stuff sometimes. Got to just get on with it.

merci pour tout ces précieux conseils.

멋진 작업이다. 나는 많이 배웠다. 고마워.

Awesome video, thanks 👍🙌👌😊

Thanks.

Impresive !

the nut on the end of the shaft is also not perfectly square and applies uneven pressure. This can be corrected using spherical washers.

thank you. really nice video and some very helpful information. i was also a bit worried about the glue coming off but there are other methods like a balancing washer that do the same job so no big worries.

nice work , thanks for shear

Thank you for video.

Зачем 2 раза править диск, сказал этот парень и обточил его 2 раза… А если серьезно, то я думаю, начинать надо не с замены штампованной шайбы (хотя это тоже важно и нужно), а с проверки люфта в китайских подшипниках и ровности самого вала мотора. Бессмысленно точить новую упорную шайбу, если вал кривой, а шарики в подшипниках квадратные. Но вообще все остальное по делу. Лайк заслужил. Одно маленькое замечание для тех, кто будет повторять: если уж вы будете заказывать у токаря новые прижимные шайбы, то имеет смысл заказать и вторую большую шайбу с канавкой для грузиков, чтобы можно было балансировать камни прямо на устройстве. Если пойти в своем безумии еще дальше, то самым идеальным вариантом было бы изготовление конусной насадки на вал двигателя, заказ новых камней с посадочным отверстием 50 или 76 мм и изготовление прижимных шайб с очень плотной посадкой на камень, которые бы оставались на камне до момента его смерти. Иначе получится, что при каждой переустановке камня его заново надо центрировать, балансировать и подгонять. Посмотрите на устройство больших заточных и шлифовальных станков - там это реализовано с завода.

bardzo ciekawy film, dziękuję!

Great explanation!

Such a beautiful video ⭐️ Thank you very much for all this important information. 🪚🛠👍🏻

Nice work ,sir !

Excellent

Man thank you for making this! Every abrasive wheel I buy is so out of balance I'm terrified the wheel might come off. Nearly every video of "how to balance a grinder wheel" is some idiot rambling and trying to figure it out. After nearly ten minutes most say throw it in the trash and buy a new one. Bench grinders not exactly a precision tool no one makes disks with options to add different screws for weights. Anyways thanks my guy!

Very interesting and informative. I am surprised that there is no mention of CBN wheels.

Back in the days the grinding wheelfactory balanced the weels with ''blymønje'' or minio de plumbo'' or lead paint''

This was awesome thanks

Nice video, thanks for sharing :)

Great video, thanks..

So thats why my bench grinder is jumping like crazy.

Great instruction, thanks 🙂

great Thanlyou

I never felt so many regrets as after i bought this grinder, it's soooo weak i can prevent it from running with 2 fingers.

GOOD JOB !!!!!!!!!!!!!!!!!!!!!!!!!! :) Regards Paul P.

Very professional work

Really helpful 👍

Interesting I checked my recently bough grinder it has a proper base plate but the disc is new and not balanced. I never knew to check that when purchasing just went to 1 200mm machine from reputable machine shop worked out great.

Geil !!!thanks allot for that vid 😊

عملك راقي👍👍👏👏👏👏

Buen video saludos desde México.

Nice! 👏

buen trabajo, gracias

my coworker applies too much pressure when he grinds so he ends up pushing the wheel out of alignment all the time , so where we used to go through a wheel in 2 years we have gone through 3 in a year

Great work! May I ask what CAD software you used?

Очень крутое видео, спасибо

Good job 👏

Very very good 🙂🙂👍👍❤️❤️
