Dads gonna be pissed when he hears that engine knocking tomorrow morning.

For those confused and talking out of their ass this is called friction drilling. Mainly used for thin metal such as piped, beams, plates/ sheets of metal etc. When you friction drill instead of removing material it melts it and creates more surface area for you tap threads and more surface area for the bolt to bite on too

When did a spark plug become a ceramic candle Edit: please stop telling me why, it was a joke. I can make the connection between the two names and the first guy to explain it did it just fine

Maybe don’t tap it like a barbarian. The way you pulled the first tap out shows why it was loose. It was nearly sideways 😂

Even though it had more threads when he was done, it's still crap. Use a threaded rivet, or weld a nut to it.

This is called flow drilling, And yes they do make a drill bit for this.

Я видел, как доктор оценил данное изделие в 250 полуляхов

I would just tap the hole the right size …saves time!!

It’s amazing how damn many people seems to totally misunderstand the entire point of this diy tip

First of all, you didn't screw it in more. Second, Did anyone catch that he made the whole larger and had to use a different bolt. In a project you have to use the right size bolt. The whole videos was a failure. There are nuts you can buy for just this purpose and the right fit. There like 5 for a dollar. They work great for just that. I like to use a needle nose pliers to hold them in place. Fingers will work too. Just to get them started. So the ceramic heats up the steel to make the whole deeper and wider then the first whole. It is pretty cool that you can use that spark plug that way. I'm sure sooner or later I can find a use for that ceramic spark plug cut the screwed size part for something. I'll like to try it on something more useful. If it works that will be a tool to have in any toolbox. Thanks for sharing your video and Idea for making holes wider and deeper. It's like not having to go out and buy any nuts with grips on the bottom of the nut to grab deep into the steel and not spin around and around. The more I think about it. The more I want to give it a try.

Now all I need is a set of different size spark plugs

Тот случай, когда копируют у Полуляха

Съемки класс,как будто яйца Феберже изготавливают.👍👍👍

Regardless of the silly tool, that's an interesting thing to know!

I was waiting for a good laugh because cutting a spark plug open, just didn’t make sense in my mind, but this might be useful. Although I’m never gonna do it

Shows it "loose" after screwing in one thread. And the diameter of the hole got bigger with the spark plug. Literally size specific and in turn. Dumb content as always.

I love that transition then plug changes it’s grip in drill vise 👍

What if the plug cracks as its spinning what is your 5 min craft for that one

The characteristics of metal in a drillhole are questionable after getting glowing red.

I tried that. It worked, but now my car is running a bit rough.

This demonstration shows why it is imperative to know the type of tap to use for the amount of steel or whatever metal used for securing a bolt! Since this steel is in a boxed formation, and is thin, use a fine tap instead of a course, and there won't be any loosened bolt.

Y'all missed the point. I know he exaggerated the point that the regular hole was not as strong as the friction drilled hole. The point he was showing is it gives you more metal to grip with the threads. An old spark plug is a lot cheaper then the other bit. This is good if you just need a few holes at your home shop.

Oh yes, I recall the time I thought, what if I cut apart a spark…oh how the world would benefit!!….indeed!

Wow ! That could be used in Fordge in Fire to drill holes for handle pins . After they temper the blade .

First tapping was dry, not to mention that the bolt wasn’t fully engaged in the first “wiggle” test. Second tapping the tap was dripping in oil.

This is called flow drilling (friction drilling) for the uninitiated and is for this exact purpose shown. Normally done with solid carbide though.

We’re all mugs for watching this

Зажал за кончик, а когда сверлит уже по другому зажат

If you use the wrong size drill before tapping it will be loose. You need to drill for a 75%-80% tap and you get tight fit. When you drill to @60% thread tap they will be loose. I always step down @1/64 or 1/32 smaller than the suggested drill size for that particular tap.

I think that this is a good idea, and can be useful in the right application, but the only downside is that the hole in the metal has to be the same diameter as the spark plug to begin with.

А взять сверло нужного диаметра не судьба? Или таких в природе не существует? Хотя... Раз есть метчик для нарезания резьбы именно этого диаметра, то есть и сверло, что должно сделать это отверстие! Логично? Логично. Да и вообще, то что получилось у "диайвайщика" на данном видео - не отверстие, а дырка.

Great now I need to take one sparkplug out of my dad's car 😶

Flow drilling. It makes an extruded hole in thin materials so you can tap more threads. Fragile bit to have in the chuck of your drill press.

Man just created a wishlist version of a friction drill.

They now make a special tool to do this in one step.

For fools who don't understand mechanics. There are threaded rivets for such holes. Turn on the brain

I’m gonna lie these videos never cease to amaze me

You made a flow drill bit. Clever, given how expensive a real one is, so long as you need them in that exact size.

I feel bad for the people who believe this stuff. Please use correct size drill bits. A good set is 100 dollars and with a steady hand and a flap disc grinder you can resharpen them and your grandkids will be using them.

People whom try to prove that they are smarter, then along comes an expert.

Wow! I really REALLY like this idea! One of the best things I’ve ever seen on KZfaq

The music is just as dope as the tool 😃👍🏿💥💯

Для дураков которые не понимают механику. Для таких отверстий есть заклёпки с резьбой. Включайте мозг

he always has the best music bro

He should've used the proper size numbered drill bit in the first place. And did you notice when he showed the bolt was loose he barely screwed in in. But after the "magic" he screwed the bolt completely throught the metal. Weld a nut on the inside of the tube.

On thin metal, NEVER tap all the way through. Back it out to leave the hole " tight". Easy to do.

ДОКТОР! ВЫЛАЗЬ ИЗ МОЕЙ ГОЛОВЫ! Ах да, 250 гиголяхов из 250и (он мне обещал что скоро будет такая единица измерения)

Well if you use the right screw it would not be loose. Metric for metric bolts imperial got imperial bolts.

Yes gives the bolt more metal to grab! But you NEED! A press drill not just a hand drill & for only that one size there's more then one bolt size out there!

Man that's amazing to evening know this. How did u even know it could do that good job man

This is a great hack for flow drilling! Thanks!

Как добыть огонь

This style of drilling is called friction drilling and it is better for threaded holes.....however I don't thing a ceramic core will withstand this for long. Friction drills are normally made from tungsten as it has to be harder then what's being drilled through. However you can shatter a windshield with a piece of spark plug....

You know your supposed to go with a smaller bit size to eliminate the looseness, a thicker piece of metal would help out too

Сверла специальные есть, которые металл вроде продавливают. Под резьбу

👍

This is what i call a helpfull DIY video!

It’s a patented product called Flo-Drill. Great tool but you have to dob a pile of goop on it before every forming or it work hardens and the threads will be junk.

What

The wall on the h.s.s is to small. Your essentially tapping a burr lol.

I'll keep that in mind for all of my exactly and only spark plug diameter fasteners I need to fasten into paper thin metal. To put it differently; this is great if you're going to bolt an anvil to a soda can!

Pretty darn clever thank you.

Great, I'll never get that 30 seconds back now..

And that's how toy destroy a spark plug

Friction drilling is a known and used machining process (might be more accurate to call it forging tbh). However the spark plug.....ya that's a new one

LOVE THR MUSIC❣️❣️❣️ And the craftsmanship is awesome too… 😉

the fuck was that

너트를 용접하는게

Stuff like this is why I’m returning to engineering school in my 30s

It tempers the steel around the hole. Just drill the hole and heat the edges up with a torch. Does the same thing.

This video is not what I thought it would be. I like it.

Actually genuinely useful

This I wish I knew when I was a heaveline/fabricator. Super awesome

The challenge is to make a thread in such short gap. So the virtue isn't in the spark plug vs the drill bit but I'm the ability the spark angled and rubbing heating effect created an extension or thicker wall for your thread in such thin metal tubbing you had or chosen to use. So yes you did good but in a thicker material or tube you'll get with the appropriate drill bit the space for the thread and you leave the spark plugs for when you need to make walls for threads.

I thought this is some 5 min craft bs then after finishing the video this is actually useful.

Makes a deeper threaded area, makes sense. How long did it take to heat the metal that hot?

One of the pipes need to be fixed with 53mm bolt, do we get a plug in that size? Or I shud put multiple holes using the normal plug?

There’s nothing wrong with using a drill bit, you need to properly size the bolt for the thickness of the material. Also, thread the bolt in more lol

Use the correct size drill for the Tap and that wont happen. 55, 65 or 75% Thread Depth. Take your pick. Plus, the Tap you used was a "Cut thread tap like is found in a Hardware Store Tap & Die set" And NOT a "Ground Thread Tap" like is used in a CNC Machine when REAL ACCURATE THREADS NEED TO BE PRODUCED. And then we have the ridiculously thin wall of the tubing offering too little Thread support per the diameter. You can also use a Tap that will produce a Thread with an oversize P.D. (Pitch Diameter) but now we'd be getting into Class of Fit like H-Limits. But... since your using Spark Plugs to make holes, I guarantee you that this is WAY OVER YOUR HEAD. Been selling Industrial Tools for over forty two years... Been there, seen that, don't be silly, use the right tools and don't cheat.

Friction drilling! Good idea.

Not bad, good idea, like the music🤙🏼

Actual process is called flow drilling. Very cool when used right.

The idea is good but drilling the right diameter hole in the first place is more efficient.

How about using the right size drill for the threads to be tapped?

Totally worth a sub.

I'll have to remember this the next time I need to tap for that exact bolt I don't know the size of lol.

Ya the first tapping was really rough and speed up compared to the second which was very slow and steady. I think this is a great idea if the screw hole is stripped as well

That works temporarily but shouldn’t you actually have at least 5 threads in contact with the side walls? Wouldn’t it be better to attach rivets or welding a double-stack of metal in the are you’re adding the threaded holes for rigidity and so it’s done in a proper way that a master machinist would support for long term solutions?

You just need to use one step smaller drill bit from an advised size for a particular bolt diameter to make it tighter than normal. Now the reason why your ceramic holer created tighter grip on your bolt is because it created longer threaded path for your bolt to anchor to. Simple logic yes!

The way he pulled the tap out on the first is crazy. Tungsten carbide bit works a little better for friction/flow drilling but it is a pretty penny so I see why someone would do this. 2nd tap is better because the bolt has more contact with metal but can’t be used in every situation but there’s no reason to over exaggerate the “life hack”, people aren’t idiots.🤷‍♂️

You are not supposed to Cut a Metric Thread in a 2mm thick Plate. You neither need another Thread Type (Woolworth or PG) or you can use These Thread nuts, which Cut themselves in a bigger hole.

Thanks for showing me how to get the most ceramic out

That's incredible!

FYI although you can flow drill with a plug ceramic you definitely CAN NOT ignite a combustion chamber with the unused drill bit……

This process is done industrially for this exact reason, so it's not total BS, but they normally use tungsten carbide bits, not ceramic. I guess if you only need one size hole and you're ok with trashing a spark plug every few holes... go for it.

Good thing they make sparks plugs in all the same sizes as drill bits

Commenters are dense. It was a demonstration. Don't assume it's just about this one scenario. If you build stuff, you'll see other potential applications where you may just want more threads from the same material.

Very elaborate and expensive way to get yourself a flowdrill, invented back in the days!
