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.

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

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.

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. 👍

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.

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

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!

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

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

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

Brilliant technic & perfectly executed, thanks for sharing.

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

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

PERFEKT ! ! ! THANK YOU. 1 * Slovakia.

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

I love it when a plan comes together!💪😜

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

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

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

Great job.. really learned a lot here

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.

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

bardzo ciekawy film, dziękuję!

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!

Bravó,ezt nagyon jól csináltad!👍🕊

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

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.

Nice work ,sir !

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. :-)

Amazing work Dude, thanks for sharing.

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.

Brilliant video once again. Thankyou

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.

merci pour tout ces précieux conseils.

Great instruction, thanks 🙂

Great explanation!

Really helpful 👍

Thanks for sharing

Good job 👏

nice work , thanks for shear

Excellent, thank you .👍

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.😃

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.

Espectacular video muchas gracias y saludos desde Argentina

This was awesome thanks

buen trabajo, gracias

Awesome video, thanks 👍🙌👌😊

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

Nice video, thanks for sharing :)

Thank you for video.

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

Nice! 👏

멋진 작업이다. 나는 많이 배웠다. 고마워.

Great video, thanks..

Excellent

Great tips

👌👍👍👍 Superbement bien expliqué

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.

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.

Buen video saludos desde México.

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.

Молодец! Всё подробно рассказано.

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

Ilmu sangat luar biasa saya akan mencobanya

damn this man seems to know his stuff

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*

Impresive !

Very, very good. TNX

Great job !!! There are commerical wheel balancing tools such as the one from one way .. but your trick of using lead solder seems great !! What glue did you use please ?

عملك راقي👍👍👏👏👏👏

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!

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.

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

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

Nice video,,👌

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

Thanks.

Magician.

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

Прекрасное видео. From Russia with love.

Geil !!!thanks allot for that vid 😊

Very professional work

Very very good 🙂🙂👍👍❤️❤️

Спасибо!

great Thanlyou

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

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

Очень крутое видео, спасибо

καταπληκτικό!

Круто!

Красавчик

is it better to bolt grinder to the table or leave free standing with rubber feet?

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

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

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

geil!

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

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.
