Why it is Not Patented? Insert Cardboard Into Angle Grinder and Amazed 

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!)))

I've only used this once to sharpen my mower blade ru-vid.comUgkxPDBfLu68o58Aw85O_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!

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

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

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

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

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

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!

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

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.

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

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

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

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

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.

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.

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

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

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

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!)

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.

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

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?

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.

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 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.

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

Would a hardwood or softwood circle be better?

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

Hai una creatività veramente eccezionale! Grazie💡👍🏻

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.

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

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

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

Хорошая идея, надо только завещание написать😂

Stunning idea

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

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

Ну блин, я думал листы железа будут пилить картоном 😆

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

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

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.

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

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

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.

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

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

This is dangerous. Basically, they use rags for polishing. An angle grinder should not be used for such things. Its speed is quite high and as someone else mentioned a little carelessness and you will suffer for life. If you are going to use something like this, at least lock it so you can have two free hands for more stability and safety. Better to use a mini drill with a flexible shaft. It will be much safer.

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.

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

*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._

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.

Variable speed grinder a must

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

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

Excellent !!!!

Well done --buffing wheel from cardboard ?--sharpens too ! NICE IDEA ---but Wear eye protection --just in case !

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

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.

Wirklich sehr gut,da hat ein alter Metaller wieder was dazu gelernt,danke 👍

Great idea for your cardboards. Another diy tip of the day!

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.

Ottima idea Maestro, grazie! 👍

Friend brother you are a genius you know how much you have haorado us thousand gradias

WOW! This is awesome... Thank you!!

Great Idea. I live in a remote area away from towns, and stores, in the bush where my shops and home are. I'm purposely removed from so-called civilization. I've come up with some innovative ideas to get me through. I appreciate making due with what's on hand.

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

Fascinating, Just do it, there will be interesting things

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....:-}

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.

Perfecto! Mui bien!

Estuve buscando el vídeo bastante gracias

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.

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.

Super ideas

It is very useful

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!

Can you make a seashell flake/ epoxy blended shaving razor next please? With a handle made of coral and clear epoxy if you can.

Nice work...keep SAFFTY ❤

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

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

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

Man... I just love that fast foward tap technique on videos like this.

Для этого есть войлочный круг , который стоит копейки, а здесь времени потратишь на изделие много, а оно дорого стоит, ведь клей высохнуть должен полностью

Or you could just buy a buffing /polishing disc.

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

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

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.

I like the creativity, and I always have wayyy too many cardboard boxes from deliveries! I wonder if it might be better to only glue near the center, so the hardened glue doesn't make areas that are more abrasive than others 🤔

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

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

Great tip! Thank you

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

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

May I ask what the blue rectangular thing is you wipe on the cardboard @2:26

Wow awesome idea!!! thanks for sharing.

I'm just glad this was done safely on an ESD mat. :)
