Top notch technique. Repair is just as good as original without sacrificing ability to torque properly. Much nicer than just installing larger bolt after 1st thread tap.
@@bonerDB The consistency of pre-made threaded rods and bolts can be... lacking since some are really snug, while others are VERY loose! IF you use them, its usually best to stick to the same source to keep the source's threads and bolts consistent and (hopefully reasonably tight) However, I've personally found using taps and dies to be much more consistent and lead to better results
Working in a large aerospace machine shop, I constantly had to deal with stripped threads in the work holding fixtures that morons would way overtighten more than they needed to be. I started using the EZ-LOK thread inserts to repair them and never had bad results from them and the repair was often stronger than the original condition especially considering most of the damaged threads were in aluminum.
I like to use Helicoil. However, I use any solution, I never waste time making the insert myself, because it is very cheap and I can get them at any screw shop. 😁
Silly me, I'd drill out the stripped hole, tap it and install a threaded insert, purpose made for the job, heat treated for toughness, and save myself a lot of time screwing around making one that won't be as good as one I could buy for .50 cents
These inserts can be bought hardened and self-cutting, sometimes even self-securing off the shelf. You can even turn them directly into a cast piece of aluminium just with a strong nut and bolt and a wrench.
True enough, though circumstances may make obtaining such a kit impossible. I, for example, had the thread to my old van's injector mount strip out and the van became undrivable, I didn't have such a repair kit, but I DID have the materials on hand to drill out the old hole, tap a thread and create an insert using a section of threaded rod, I drilled a hole through the middle of the threaded rod, tapped a new thread to match what it should have been and after applying thread lock to the outside of the new insert, I wound it home. That van already had in excess of 175'000 miles on the clock and it lasted another 35'000 miles before the old beast died a final time (not due to injector failure)
@@GaisaSanktejo That's amazing! I respect people that are creative with solutions so much! Still, if possible, there are some things that that you can buy and that make life so much easier. Like those inserts.. You can make them yourself and if you do, props to you, but if you can get them premade, it's great to have them.
@@KevinATJumpWorks Thank you and thats true enough, IF you can both afford and obtain premade items, go for it!. If not? You learn to improvise, fast 😆
@@GaisaSanktejo Actually, that 'doing things yourself' vs. 'buying stuff pre-made' is such a tricky topic. On one hand, one learns so much by doing stuff oneself, but on the other hand, you can operate on a more abstract framework if you can simply buy the stuff you need. You can focus on the 'big picture' without having to go super deep into every little detail. On the other hand, you might not get to know crucial details like this that, in turn, may slow you down in the long run. So difficult to navigate. But that being said, both perspectives have merit. :)
Kent Moore tools makes a kit called a time sert. It comes with a drill bit and tap plus the threaded insert. Way stronger than a heli coil. Used in my career at GM
Project Farm did a test on this a while back. Both were even in terms of strength with the fasteners failing, but the time sert costs a lot more and is harder to replace if the threads ever get messed up.
maybe it's already somewhere in the comments, but what did you use to secure/glue the self made outer thread / helicoil? and would it be durable or worse to use a piece of aluminium for the thread insert?
37 year machinist answering your question. I do this type of repair sometimes especially on a part like this. Either Loctite or a similar adhesive can be used. Basically superglue for metals if your not familiar. This looked like black Loctite which once it sets it has to be cut out. Heat will not even release that stuff. On this particular part that has a thin wall using something like a Heli-coil can cause the hole to break out on tightening the bolt as the coils tighten up in the hole and try and spread out. So a solid piece inserted and tapped is better. Also its a good repair as a part like this is rarely taken off and the steel threads will not gall like aluminum. Hoe this helps.
@@martinswiney2192 i dont have the years of experience as many others here, but i have found my thing in repairing old motorcycles for me and other people. I have used this method a few times but i glued it with blue loctite (learned from someone else) never seen someone back with problems but i never knew i made the right decision. Later i started to make them out of aluminium because someone said its really bad to make them from steel.
Can someone help me understand why does he not just use the initial tap he makes and put a bolt in it. Why does he empty a bolt in the middle and put that in again?? I have a similar issue and in my mind im thinking of just tapping the hole and moving a size up and directly fit a bigger bolt in it. Im not sure what im missing.
good fix, but why did you not drill it out to a tapping size for a helicoil then insert a helicoil thread? The helicoil threads are stronger than the original thread.
@@capnskiddies I don't his location has anything to do with it. I have done similar with turning and press fitting a diameter into it because there was not enough wall thickness. Helicoil, recoil etc.. all provide worldwide. Nothing wrong with his repair except do we know the steel grade of that rod?
Maybe he can't get helicoils. Pretty sure that steel rod that he drilled and tapped is stronger than the aluminum it's being put in. This is a solid repair.
If true strength was required, if it was 5/16" or 8mm mangled thread should've drilled 5/16" pilot. Now make stud, one side 9.5x1.58mm(3/8"x16)the other side of stud 5/16or8mm dia, thread and cut for proper length with nut installed or just drill and tap for 3/8x16 bolt, done
Question: Can I use the dye to replace a stripped nut...particularly if the threads are not aggressive enough on the replacement nut, and the axel although repaired, still has shallow threads.
Welding isn't good (I'm welder) (spawam rury na elektrowni) You put heat ( energy) in element and material in welded place isn't as strong as before repair. Taka metoda jest o wiele lepsza, bo zawsze bedziesz mial otwór w wymaganym miejscu no i nie zmieniasz właściwości (wytrzymałości) elementu
Beautiful work! You inspire us fabricator/machinist to find solutions to any problem!

Top notch technique. Repair is just as good as original without sacrificing ability to torque properly. Much nicer than just installing larger bolt after 1st thread tap.
Are you sure its better to use this technique than bigger bolt? I'm just curious 🤔
@@bonerDB Using a bigger bolt involves drilling out the other half of the case.

What if you dont have a lathe.
Saying that great work.
Myself....I would prob fit a larger bolt....having only basic kit.
How come is that 'much nicer'?
Super clever trick….I’ve never seen this repair done this way before. Very nice work my friend 👍🙂

I've seen it tested and can confirm that the repair is stronger than original
how many uncles is it raised to the maximum screw thread?
The evolution of a helicoil. Backtrack to how it started.
You cant get a Helicoil as good as that
Helicoil is junk compared to this

There is always one.
Well, good luck finding those insert in the third world
I’m thinking they have no part stores to buy a Helicoil

Nice job! I like the way that looks better then an insert type fix. You can't really see your repair job.
This is a good technique 👍!

Wow, i solved this problem with a helicoil, but this looks much more durable. Great inspiration!! ❤
❤️
Home made helicoil. I would trust the strength of this over a store bought helicoil.
nice job, expensive tools tho :)
3:53 can you tell me what’s name of this tool??

You can also repair with a triangle file. Do that on the bolt, use a thread chaser on the nuts.
Experience ones does the job like this and hats off to see your talent
Thanks
I've had this idea, and done it before seeing your video, glad I see some other out of the box thinking people like me :)

What is that black fluid u put on the bolt
Epoxy steel
Pretty cool! 🍻

Better than helicoils which always come loose!
Is that JB weld that you add to hollowed out threaded rod?
Also very nice work by the way. Very creative!
Don't they sell those threads sleeves?
It's good technical work 😊
Nice job
Thanks My friend
Very well sir. I got this idea and maybe i can make it my own.

Similar to a time sert. But I doubt those are available. Good fix if one has the room.
How much is the cost of repair?
What is tab and drill size
Good job.
Thanks 😊
Super job
Thank you for watching ❤️
Anyone know how to remove the remains of aluminum threads stuck inside a steel nut?

not much help for me since I have no idea what you are using

Because he's in Pakistan. What you've just seen is the closest they have

That was an aluminum rod.
@@kevinpeterman7127 no, it was mild steel. Aluminum would have been a lot more silver gray.
A Heli-coil works just as well and saves time with fewer steps.

Think you have bigger problems than the threads, how about the cracks in the case itself
I was looking at what I thought were cracks too, but I took a closer look and I believe they're actually mould seams

Nice work but expensive tool. Me lacking access to lathe machine

Do minute ka khel he mare samne 😅
На клей нужно было заворачивать ввертыш! Иначе потом болт может и сам ввертыш выкрутить! А так - идея хорошая!
Probably $1000+ at a mechanic and they wouldn’t even do it correctly.
Now if there was a video showing this on a car engine of 08 honda accord I would have use but I'm guessing it's impossible
Has anyone ever filled a thread hole with jb weld and just used a self tapping screw ?
there is a easyer way ...HELI COIL !!!
Not sure why go thru all that trouble.
HELI COIL WEAKER
La pose d’un helicoil ,est beaucoup plus rapide ? M6 M8 etc……..
Da gibt es Gewindeeinsätze für, Bearbeitung zirka 5 Minuten. Warum so ein Aufwand?
I do it with brass rod 5/16 x 22 tpi outer then M6 it works very good and does not slip to a long time
No need of doing M8

Well I guess if you don’t have a helicoil this works really well . . .
Could have stopped at 1:45 and just used larger bolt
😆🤦🏻
So basically he made a helicoil out of a bolt. Okay, whatever fixes the part...
