I was a metal worker. So I use grinders quite a lot. I've seen discs explode, (quite regularly) I've seen people catch loose clothing in them and the grinder has climbed up them and hit them square in the teeth. I've had it happen to me and luckily my tshirt jammed it up just below my neck. I've seen all kinds of accidents with them. Even a fine disc can chew flesh up VERY quickly. I just would never use a grinder without anything but 100% respect. As manufacturer intended. Edit: it's cool to read the working men of the world in agreement with regards to safety, because I know it comes from experience and respect for yourself, your trade and tools. Also, it's nice to have a shared experience and respect with people in the trade from round the globe. All the best from England.

WOW...that's almost as good as the polishing wheel that i got from Harbor freight for $1.99 but alot more work.

Прикольно получилось! Но из валенка быстрей и надежней!)))

Mission accomplished. 4 minutes of my life I'll never benefit from and will never get back...

For all of everyone's iron polishing needs. Another idea is to go out and buy a polishing wheel.

Обожаю таки лайфхаки, когда есть деньги на DeWalt и нет пары долларов на полировальный диск))

I've only used this once to sharpen my mower blade kzfaq.infoUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 but so far very happy with it. I've never used one of these so took me a bit to figure out how to set it up but once I figured it out it did the job just fine. This is likely a single purpose tool for me to use on my mower blade and possibly the occasional axe sharpening so didn't see any need to spend a lot....this will do just fine!

Let me just waste an hour of my time to save $2

Here's a tip, while buying the buffing soap buy a buffing pad at the same time from the same place.

Для меня это диковато потому, что есть войлочные круги, которые этот эрзац из картона не заменит.

So you went over budget on the DeWalt grinder and couldn't afford a polishing disc then?

Putting an angle grinder near a knife like that seems like buying a ticket for the Darwin awards

Гениально! А не подскажете, как из стула сделать табурет?

Wow! Not only did I have several old boxes just sitting there, uselessly waiting to be recycled, but I also had several hours without anything to do. This solved both my problems! What a life saver! I tried to impress my wife with her new mirror polished clothes iron, but she refused to carry it in her purse as a vanity. The ingratitude!

So either spend half a day crafting a blade with materials you don’t even have unless you buy them OR spend $5 and buy a polishing wheel…

Fine grade wire wool for the iron works a treat and a lot less hassle. I've used autosol and wire wool for years for many metal polishing jobs, doesn't take long either. Even used tin foil on to on some jobs. As for the knife, I wouldn't use this particular idea. An old leather belt with the same compound is great to strop with👍🏻. I can see theis wheel useful for de rusting large pieces though.

Having shiny tools is far less important to me than not inflicting bodily harm on myself. I like my eyeballs too much to try this.

Why can’t y’all just appreciate his creativity!? This is a very cool idea!! What if you went bankrupt, you’re broke, you need to sell some silver plates or some tools you got lying around and can’t afford a buffing pad etc? Now you can get top dollar for your personal items cuz you were smart enough to know how it make them look brand new without spending a dime! I for one admire the ingenuity!! Thanks for sharing!!

I've been a metal fabricator for almost 35 years and a trick I was shown years ago was basically the same thing only on a bench grinder using the grinder with the guard reversed for reverse rotation and buffing compound for sharpening knives. It works great.

Ну блин, я думал листы железа будут пилить картоном 😆

Спасибо всем тем кто посмотрел этот ролик! Теперь автору хватит денег на полировальные диски здорового человека и ещё на хорошую болгарку останется! 😁

what type of polishing compound did you use ? Love all your videos.

You know they make pads that do the same thing and are safe to use....and are inexpensive. Why anyone would put something on an angle grinder and spin it at 9,000 - 12,000 rpms is a Darwin up and coming runner for the title. Cardboard or anything.

У меня похожая штука в работе еще с советских времен. Только диски сделаны из лосиной кожи толщиной ~4 мм (были тогда такие магазины "Сделай сам", купил там обрезки) , 6 штук в стопочке и зажаты между двух кружков из фанеры. Схвачены на гайку болтом М10, сточенным у хвоста на трехгранную фаску под губки патрона дрели. Намазываю её зеленой пастой ГОИ. Работает, как Золушка уже 4й десяток лет. Удобная вещь и по ходу часто требуется.

I've been looking high and low for a way to polish the bottom of my 21 year old iron and stumbled upon this video. Oh happy day! What a time to be alive.

It is already patented..... and refined. Consider this as a " back to basics" tek. I have never seen nor done this nor am I claiming to have knowledge of the origins of polishing wheels but concepts are so similar that it would be hard to believe that this one hasn't been done ( probley for money) somewhere. I am not trying to take anything away and I really do like this idea.

Use a large metal-tooth hole saw instead on a stack of clamped cardboard to do it faster; you'll get the circles and holes quickly.

Хорошая идея, надо только завещание написать😂

Доктору DIY отправьте, он точно знает, что с "этим" делать😁

Neat play time trick...but this buffing wheel is too stiff as evidenced by the uneven surface...

Amazing idea. Thankyou! I am a hobby welder and need to clean out some rust every now and then.. will try this.

For those who think this is a great idea, first try using a 4000 rpm grinder rated pad on a 8000 rated grinder . Make sue you had full PE before trying this, then come back and find out why this is not patented

I love 'Thinking outside of the Box' & diy ideas.. I can't help but believe this will deteriorate quickly. Super quick if it gets wet. This being said, his results were nice. Saving older, damaged foam pads is my go-to for junk work.

One of the first clause in patent law is that it should not be obivious and that it should be a unique invention. No one is stopping you from making it a product and selling it in the market.

This a save!! Bloody amazing!! Thank you Bob England

Yep one buggered up iron with blocked steam holes. However cardboard was a great item in my military kit, used it with brass cleaning fluid to polish brass belt buckles etc, very effective (but strangely only needed hands to do it!)

*Congratulations, you've invented the polishing wheel.* _Luckily I can buy one for a couple bucks and don't have to spend two hours making one from scratch._

This sort of thing always makes my mind wander to the next level. I'm anticipating a slow day at work so I'll be using this idea to make a full-sized spare tire for my car. What could possibly go wrong?

Give the guy a break and congratulate him. He just invented a polishing attachment with all the elements of danger we didn't grasp around age 14.

I've seen similar done with a similar thickness of MDF. Of course, the cardboard would be safer as if it does self destruct its going to have less mass behind it

This must be just the 1st episode of the series of 2 videos. The 2nd episode tells you how you wear yourself into a bulletproof protection equipment, to not get yourself damaged when that piece of cardboard start flying astronomical speeds. The 3rd optional extra episode could tell how you protect the room around you to not get damaged by those same fragments of cardboard.

It's rare you get to hear about something no other human has thought of and it's even more rare to witness it. Behold the only recorded moment in all of this great universe's history of an iron being polished.

Would a hardwood or softwood circle be better?

Спасибо, Уважаемый ! Главное, видимо, чтобы картон не задымился, от температуры, при трении. Микро полировка - супер !

I don't know which is more time consuming - reading the hilarious comments or watching the hilarious video. I applaud the poster for making money on this content. Cool.

The editing process to shorten video enough to keep people watching till competition is more remarkable than final outcome for me

I always wondered what the early days at 3M were like. Thanks for the history lesson.

Would like to see the knife edge geometry free hand with a polishing wheel.

Polishing takes off material so keep that in mind if you're going to try this. Look closely and you'll see its not completely flat. They also sell polishing wheel which i would trust a bit more. Cool video though

This is called a rotary polisher. Usually it operates at a slower RPM and uses a type of fabric to hold the polishing medium with a more durable base. There have been higher RPM polishing tools using a similar type of corrugated paper as well, however usually not quite as high RPM as an angle grinder. It can be overly abrasive at the angle grinder speeds. Of course this depends on purpose. You'll find that it is very easy to ruin the symmetrical edge of a blade sharpening it with this method. However, this method could be useful to remove surface rust in a heavily degraded blade.

Hat a health and safety nightmare waiting to happen lol

Muito bacana como faz com o papelão. Boa ideia para fazer no quadro da bicicleta.🙌👏👍👍

I imagine because you're not showing how careful you need to be with it not to rip the cardboard and have the thing come flying off at a great speed.

You cannot deny that the iron looks a lot better after being polished with the cardboard.

Polish and a buffing wheel seems to work well also. I build mine out of popsicle sticks and marshmallows !

Можно ещё из старых джинсов кружков наделать, собрать диск для полировки.

Or you could just buy a buffing /polishing disc.

Use of cardboard is definitely creative, but was wondering if there is a way to attach it to a sander instead, because of safty concerns

Wow. Really made that harder than it should’ve been. Glue all the cardboard together, lay something heavy on it, THEN cut out circles all at once. Done.

Ну да хорошая идея предумана зделал полировочный диск из картоны. Можно ещё лучше войлок или валенок круг вырезать и полеровать им. Это лучше чем картон.

*Instructions unclear.* All of my knives have a mirror-like finish but all my hand tools are now razor-sharp.

Complimenti per l'idea. Non solo è un modo per riciclare oggetti destinati ai rifiuti ma diventa un nuovo utilizzo molto utile e meno pericoloso e più economico rispetto ai soliti dischi abrasivi.🤗

what was the stuff you put on the grinder before you sharpened the knife?

Hai una creatività veramente eccezionale! Grazie💡👍🏻

Зеркального блеска на утюге я не увидел, но грубую очистить произвести удалось. Не думаю, что картон, даже если порвётся, то причинит очень тяжёлые травмы, но всё-же войлок обрабатывает аккуратнее. Можно даже для этого использовать остатки паласов и различных ковровых покрытий - также из них круги вырезать и позировать различные металлы до зеркального блеска.

This feels like a solution to a problem that doesn't exists.

this makes me want to actually use my bench grinder with polishing wheel that i have not used yet LOL

Я афигел просто с этой идеи! Моё почтение за видосик. Жду каждый с нетерпением. Я и сам являюсь автором, люблю ваши видео! Снимаю про быт свой, простого парня инвалида детства, своих зверят, и свой дом. Сложно мене даётся контент, стараюсь ровняюсь на вас!

Just use a soft scourer on the iron, done in 30 seconds

If only it were possible to buy some sort of ready-made buffing disc for about £3...

THANKS FOR THE WONDERFUL TIP & VIDEO! YOU CERTAINLY ARE A SMARTIE!!! GOD BLESS!

Been polishing gold for years with paper . God-bless you and your family Amen and Aloha

Yeah the guy just re-invented the polishing wheel, but i think it was more just a neat demonstration how well carboard actually works. Im curious if the layers of glue affected anything.

I experienced cardboard as nice go to when figuring some stuff out like making a pre-template for wooden cutouts, but thats where the good part ends, anything else it is way too fragile in most cases. I know that theres doors and walls and even furniture made of the same principle, but those are produced to last, not like packaging cardboard boxes

I have an original 63 corvette and I’m going to try this on the bumpers!

При следующей переустановке круга, (когда он понадобится), он не отцентруется и будет бить.🙁😕

Definitely works much better if you crush the cardboard to make it more dense. Also seen it work with plywood, particle board, heavy cloth, heavy paper, or anything porous and strong enough. Be very careful if it catches it can explode.

I also found that NOT phuking up my iron, cutlery, and tools, makes this an easy task !

BRILLIANT!!!! No one knows when the stores will be unavailable to purchase a buffing wheel.....just saying, learning to make one from cardboard is a very USEFUL idea, thank you very much for sharing it....:-}

That reminds me, I've been meaning to polish my channel locks. They have never looked the same as they did when I bought them in 1978 at the flea market in San Andreas. That has been bothering me. Thanks for the hack.

Nice video, I enjoyed it and gave it a thumbs up, Its not patented because it is dangerous, and when it eventually reaches the glue parts on the spindle it will be more abrasive than anything or glue bits will go flying. Angle grinder needs to have lots of respect and eye safety, I'm a normal person that uses an angle grinder a few times a year, already have had a sanding disc dettach itself from velcro holder and fly straight to just below my eye and also while cutting a cupboard in half in a difficult to reach spot the grinder crawled out of my hand with a wood / aluminium cutting blade and crawled right into my finger fortunately i pulled away from it, it left a deep gash. Angle Grinder Respect +1000

I will make this out of the amazon box that the polishing wheel was delivered in.

Nice trick! Maybe a little too hard for most polishing works...

Seems like a lot of trouble to go through for something you can buy for a few dollars.

Pretty cool idea, you could patent it, but i think the main factor why this isnt out there yet is the impracticality and time of production plus the huge wiggleroom for error... normal polishing discs are very straight forward to produce and crave very little time

Hey, that's a buffing wheel, except , a lot more work.

Thanks for sharing..best knife sharpener and buffer ever…

Holy crap that was a lot of work to make a disk that is surely available at the store for a few dollars.

Thank you for making this video. Very good for when you can't just go out and buy things as several geniuses mentioned. Content appreciated

I mean how much is a polishing wheel thats designed and built for this purpose? I cant imagine the price warrants this when considering it will last longer and perform better. Probably safer too. Could see this being a potential fire hazard or might even be more likely to catch on something.

Вау, чувак, ты изобрел полировальный круг!!! Поздравляю.

I myself have used multiple sizes of grinders on almost a daily basis for twenty plus years. I have learned the larger sizes like 10" are far less dangerous due to the fact that they demand the respect of your attention to safety. The smaller 4.5" or 5" grinders seem to give a disbelief that they somehow aren't as dangerous...this is the exact opposite of what really is, I have been injured more times and in fact damn near lost a thumb because of it. The smaller the more deadly in my personal opinion. These things are not to be taken as anything but deadly or at the very least extremely dangerous to handle. That being said, I have come to believe that the cordless versions of these are substantially safer when doing something questionable because most have a clutch which I've never seen on a hardwired grinder. Just my biased opinion of course.

They already make that tool. It's usually used for putting a matte finish on stainless or aluminum.

I am so proud that i do not have a grinder! This is a blessing.

There are many products that are not Patented or Commercially produced , because of OHS Risk ; Injury Liability & being Sued for damages,,, this one fits that category, perfectly.

Needed to explain to a young colleague, we don’t have time to do things the ‘quick’ way, nor can we afford the ‘cheap’ way

Антипригарное покрытие стало как новое. Надо подумать где теперь его использовать. Может в качестве вулканизатора?

Very good. I'm not a master fabricator but I learned a lot about polishing working in manufacturing. Cardboard is amazing. So versatile.

If you use the right kind of wood disc it just might be useful for cutting something especially if you want to impart a smoky flavor to what your cutting

Can I get my angle grinder back please? I need it to do some - angle grinding!
