This is one of the great benefits of todays online media. Before all this, you just have to go off of someones word but now a dude can afford to run this test and then post the results online for the world to see what the truth about the subject is. its a weird world but a good one
I am a woodworker who has never used a disc grinder, yet your presentation held me. You are smart and engaging, without a trace of the bad humor or baiting that mars so many other videos. Thank you.
holy fucking shit this is the most thorough testing I have ever seen. Project Farm would be so envious of this setup =). Every welder on earth should be watching this.
I have run a belt sander for the last 15 years of my life and I've used sandpaper for the last 30 years of my life. I figured pretty much all sandpapers the same. It wears out quick. It clogs up quick. I recently got a ceramic belt for my belt sander + the minute I touched a piece of steel to it. I realized that I was completely wrong! I will now only buy ceramic. Aluminum oxide and ceramic sandpaper are not even remotely comparable. That ceramic belt can eat through a 1-in bar of steel about as quick as an aluminum oxide belt can eat through pine. It took me 29 years to figure it out but I'm sure this translates into flap discs as well.
The methodologies behind testing interests me just as much if not more than the actual testing. Thanks for showing all of that and your thought process!
Many of the young engineers I see have very little fabrication experience,I hope channels like yours encourage them to get more hands on. I love the way you make the test rig to measure the critical specification of interest. Its an education seeing how your rig is designed, constructed and tested itself. Real Science. Excellent work.
I am impressed with the dedication you put into the tests and efforts to record. I don't know if you thought it would get so involved or not but just how you used your tables to make complete perfect situations to a human doing this. If you were hiring someone to do this kind of grinding on say a project and you wanted them doing the work properly, your test equipment would show the human how you require stuff done. Expensive for absolute sure but your aware of stuff like this already..... great video, a ten out of ten!
Thank you for doing this. With so many brands and price points out there, it really feels like gambling every time a purchase is made. Looking forward to seeing the results!
I know folks will say this is a waste of money and time considering the cost of the test items, THE BUILD IS THE PURPOSE great video for our youngsters
Thank you for including the pitfalls and challenges of the process. It always feels nice to see that everybody else deals with the same crazy problems that anybody who invents/creates things comes to know and love.
Well done Sir. Your striving for a true scientific experiment and showing the process all through the setup is so entertaining. I have watched many a TH-cam demo and comparison of tools from wood, machining, garden tools, heavy equipment, batteries, plumbing to TV's, speakers, amps, computers, phones, tablets and networking equipment. NOT ONE, not a single video, come anywhere near as unbiased or fair. And your sense of humor makes it all that more watchable. Your one of my all time favourites. Thank you.
I sure appreciate you putting so much effort into researching flap disc quality! we have dozens of dewalt grinders at my fab shop. one is mounted on 15 foot pole, with the paddle switch taped over, and it fires up as soon as it's plugged into an extension. I don't think it's a very old grinder, and it has been replaced a few times. never had one that needed a reset like that.
Always really impressed by how well you guys pump science into the fab shop. Nice work. That’s tedious af! I’m excited to see how my go-to discs do. Been waiting for this vid for a long time!
You've reached Mythbusters level of dedication, blast shields, remote swiching and slow moes. It's been a journey watching this channel grow. Will be watching the rest of the series.
This is Mythbusters level of testing! Really well produced! These educational videos should be shown in school when you study welding/farbication. Not only to to learn the outcome but to learn how to test and evaluate results.
Jason, thanks for All your Ingenuity and Hard work! You do the things that we don't have time to and provide excellent information to educate even the dumbest of us 😂 keep it up and we'll keep learning😎
Please please please please please keep doing what your doing I love hearing your brain threw these videos. You inspire me to do what you do and other things. I have a similar mindset and I love seeing others portray the mechanical mindset and engineers mindset.
this is really valuable work. thanks a lot for doing it. I doubt the manufacturers even do this type of testing. This will save lots of people lots of money and time.
This is super cool and it's obviously going to give you good comparisons between discs. But when it comes to the reviews I think it's good to keep in mind that this isn't the only use-case. The angle of attack between the bar and the disk is super aggressive at 90deg, but when grinding down a weld it's much more shallow, kinda like you showed in the animation at the very beginning. And I think the hard impact of the disk hitting the edge of the bar is going to kill disks faster than normal use would. Still a good comparison between disks but not necessarily a good comparison to real life use.
Ohhhh mannn what a treat 😁, and what an eye opening series of tests!! I have long wondered what and how these companies test their products and label them “ the best on the market “ because it seems like they all do it but of course they can’t all be the best lol 😆 I gotta tell you Jason , your products and channel and the tests you do are for real second to none 👌👌I could watch your videos 24/7 lol
This is one of those areas like cooking or workouts where it's easy to find something that works good enough so no one bothers to find out what's actually better
Damn, now I want to know this about fibre grinding disks/pads The ones my company buys go blunt fairly quick, they are still fine to grind most stuff, but struggle at the final mm when grinding perfectly flush to go to powdercoating. I bought a couple of 982c cubitrons and they are great, but 6 times more expensive so no way I'm convincing the boss to buy them
Tip of the hat for real testing. Flap discs kick like nothing else if they come apart. Have never had an issue with the quality brand I now use. And they do last longer and perform better. ❤
Consumables are one of the things that are hard to dial in. Can be a project killer because of expense, Thanks for doing this! Time is bucks on an hourly project.
It's kinda crazy that thorough and rigorous testing of consumable things such as flap discs is something that people want to watch, even if they've never used one, and probably never will. transparency and two way communication in standards testing is something that really can and does appeal to pretty much everyone, and yet there's basically no one out there that does this commercially. I'm glad that we have Fireball Tool, and Project Farm that do this kind of testing for us. One thing i do kinda wish was a thing, or at least an easier thing for people like the folks here at Fireball Tool and Todd over at Project Farm could do, is to be reimbursed by the various manufacturers for the equipment they've purchased. I do NOT want the companies to send the equipment, because that opens the doors to cherry picking. the reimbursement would need to be completely string free though, beyond having their product used in a video. no controls over what is said or shown about their products, and no say in how their tested or used. I just don't think most manufacturers would go for something like that, even if it would benefit them all in the long run, regardless of how they perform.
Thanks for doing this comprehensive testing! Excited to see the results. CGW has been the go-to brand in my shop for a while now and I'm curious to see how they compare to other brands value-wise. A Walter salesman stopped by a while ago and tried to convince me their longevity is worth the extra price, but I don't see it. I did appreciate the free samples though!
I hope you're publishing all of these tests/findings! It would be cool to have a general "Best shop tools" hardcover workshop book with all of the information in it.
this reminds me of the Last of Us TV show. in it, one of the characters rigs up a defense system that is a set of pipes that connect to a massive natural gas source that he can turn on with a single ball valve. to actually turn the gas into flames though he also uses a bunch of angle grinders that are held in the on position but their power is all wired to a single switch, and the grinders all have bolts resting on their flap discs to throw sparks into the gas. its a pretty ingenious way to create a ring of fire around your house and it would actually work lol
I’m really curious to see how well the Pferd discs do! Great video and keep up the good work. I hope you make back the money you invested because this is probably a very expensive video. Ha ha!
We all know DeWalt are the real deal, if you're working as a a hobby a few hours on the weekends, a cheaper brand might be better for you. You don't need a Ferrari to go buy groceries... But if you're doing heavy duty work, hours and hours every day... Well, I'm not rich enough to use cheap tools...
K I S S... Keep It Simple Stupid 😅 I asked one of our machinists who had no idea what kiss meant. I asked him to build me a fixture and keep it simple stupid. Tell me when you're done please. Thank you. I walked away. I got a call from HR no one ever wants a Call from HR. Because he was a new employee and didn't like to be called stupid. Because he didn't understand k i s s. He ran crying to HR. That's the day the word kiss was removed from the vocabulary of our machine shop operations.
Would love files and analysis data as 6 hours per disk and 31 disks is almost 5 straight weeks of 40 hours. Love the single lads input but maybe allowing a fuller understanding of the data might make your point clearer. And huge note as well on statistical analysis… you can always make your results fit your hypothesis. It’s your peers that determine if it’s statistically significant.

its a weird world but a good one
these tests are amazing to see. Your file test broke many long held opinions on filing. thanks. I will watch video now
I have great respect for the amount of work you and your team are putting into this. It can't be easy...so thanks for doing it. Great job!

Holy crap. This testing really turned out to be a herculean task.
you and project farm are my go to channels for reviews

2 full length fireball videos in 1 month. Must be Christmas.
I spend thousands on abrasives at our shop monthly. I HAVE TO see the conclusion of this. We are currently using CGW.

Thank you for going to all this trouble. I am sure each company is sweating to see how the results shaped up.
Talk about an idea spiraling down to a grinding crawl. Mercy!
I can’t comprehend the ballooning cost of this experiment.
Thank you for including the pitfalls and challenges of the process. It always feels nice to see that everybody else deals with the same crazy problems that anybody who invents/creates things comes to know and love.
Good thing a viewer sent that grease for the grinders, it's not something you'd otherwise find in any workshop of a decent size :-D

Crazy amount of effort nice work! Can't wait to see the results!

Quick shout out to your content. Really good. I want a DYI fixture table. No. I must have a DYI Fireball table. Santa? I’ve been damn good. Kinda.
Always really impressed by how well you guys pump science into the fab shop. Nice work. That’s tedious af! I’m excited to see how my go-to discs do. Been waiting for this vid for a long time!
Always great to see people truly trying to find out something
You've reached Mythbusters level of dedication, blast shields, remote swiching and slow moes. It's been a journey watching this channel grow. Will be watching the rest of the series.

This is absolutely amazing!!! These are the kinds of tests we all want to see! Please keep doing videos like this!
Great idea! Jeeeezz that is a lot of work. Great consumer support; for all of us. Thank you!
This is the most comprehensive and accurate test of abrasives i have ever seen. I can't wait to see the results!
Some vacuum dust collection in the grinder shields might make your days more efficient.
Jason, thanks for All your Ingenuity and Hard work!
You do the things that we don't have time to and provide excellent information to educate even the dumbest of us 😂 keep it up and we'll keep learning😎
Holy cow. That's some serious in depth testing. It's awesome
You guys went above and beyond for this test.. Wow, talk about a lot of work.. Thanks guys !
I love you and your efforts, man. Great, informative video. I hope you keep this channel going in perpetuity.
Good lord. Incredibly robust testing. I feel like I should make 10 youtube accounts so I can like the video more.
It is unbelievable the work you put in. Amazong test.
Man, this level of testing makes project farm look like a child's project.
Incredible testing! The first and most accurate test I've ever seen on flap discs. Looking forward to the next episode. 👍
I’m staggered by the level of work and forethought that’s gone into this! Amazing effort and much appreciated
Wow, Amazing video! I had no Idea how complicated this would get. Thanks to all of the Team for all your hard work!
If you and Todd from Project Farm get together, I'm pretty sure you can solve cold fusion.
Please please please please please keep doing what your doing I love hearing your brain threw these videos. You inspire me to do what you do and other things. I have a similar mindset and I love seeing others portray the mechanical mindset and engineers mindset.
wonderful job to Conrad the editor you're the mvp here
The dedication to the experiment is impressive, man.
I have used induction heater for years and really love it
this is really valuable work. thanks a lot for doing it. I doubt the manufacturers even do this type of testing. This will save lots of people lots of money and time.

Amazing how dedicated you are to the metalworkers out there💪🏼 keep up the amazing work and a big thank you

what a monster project...i love it
Holy Moly, Jason!!
This was beyond spectacular.
As far as I am concerned, this is why TH-cam was created.
Absolutely amazing!
Thank you!!
This is mind blowing. Glad you have a nice team to handle thata amount of work.

This is f$&@ing amazing. I truly appreciate the work that goes into this.
Consumables are one of the things that are hard to dial in. Can be a project killer because of expense, Thanks for doing this! Time is bucks on an hourly project.
Talk about epic and crazy projects :)
This one (like most of your videos) is very cool and absolutely extreme!
Hose clamps were the real MVP today

Woow!! I bow down in admiration fore the new testing king!!! really good work as usual!!! 🙏👍♥️🇸🇪
builds complicated rig to test flap discs. "we need to protect the cameras" eh, cardboard will be okay haha
I hope you're publishing all of these tests/findings! It would be cool to have a general "Best shop tools" hardcover workshop book with all of the information in it.
I've never even owned a grinder yet I am invested in this!
Ha! You went from "keep it simple," to quite scientific. I like how your mind works.
Jason, thank you for this. You and your team, are doing God's work and we all thank you for it. I'm excited to see each and every test.
This is very valuable information. Thank you!
Wow. This is some dedication!
10 lbs pushing on a relatively flat disk on a plate is way different than 10lbs on a small square bar. pounds per square inch...
Um, excuse me Sir...
...your sketch promised us an emo robot!
Shout out to that ACE Hardware Bucket.
oh my goodness...you really went down to the bottom of the rabbit hole.. xD
That is impressive. Can't wait to buy only good stuff thanks to U guys :)
brilliant test

You are doing great. ^_^ Your channel is very informative and interesting. Wish you success.
This is incredible
This is awesome, and I don't wish misery upon you, but please also do this test with a harder steel as well. Thank you :)
I’m really curious to see how well the Pferd discs do! Great video and keep up the good work. I hope you make back the money you invested because this is probably a very expensive video. Ha ha!

Well, I'm not rich enough to use cheap tools...
Now this is testing.
Not all disc are created equal. And that's a fact we all can agree on. Lol
God damn that's a lot of editing, so many caneras
Wow! Standing Ovation!
This is awesome. Project farm for fabricators
You do realize that you're emabarsing the current "scientific community" by publshing things like this so widely. Please continue!!
Sparkmatic 5000!
What a task !!!
So impressive!!!!!
Fireball Tool's channel is the Torque Test Channel for fabricators.

Project farm gonna have to hire a bunch of people and step up their game. Jesus.
Thanks for doing this, every time I go to buy flap discs I question how good they will actually be. Did I waste my money?
This would drive me crazy to do this.
