Thread repair

BODGE

[IThurts2J1zz]

Wouldn't it just be easier to solder the inside, drill it, then tap it?

[jrstow86]

Uhh...poorman's tig?

[phyriz007]

Since it doesn't seem to stict to the steel, could you use the shank end of a drill bit in the hole followed by a tap? Would you be able to twist the bit out? Then you would at least get a proper cut thread.

[par4par72]

This is perfect. STI Coils, STI Taps, Inserting tool, Tang Break-off tool or solid inserts, cost a lot of $...Use them if they call for it. but for a cheap, fast fix this is optimal.

[Nik1k37]

Richtig geile sache :O

[FactoryDragon87]

Bad way to repair the thread in THIS way!!! Thread need cut by thread tapping tool!!!

[dougspair]

...Just say...TIG...!!

[mayorofperryville]

retap the hole to bigger size moron. What a waste of time and energy!

[mainman2999]

This is some kind of practical joke yes? Soft solder to make a thread? what sort of bodge engineering is this?

[mainman2999]

@jbutta1285 hi, no, that was DEFINITELY TIN LEAD SOLDER!!! you cannot just stick aluminium to metal like that, you have to WELD aluminium to aluminium which means you need to MELT both metals together, this video is a joke, making a weak thread with no strentgth at all out of a lump of solder!! also, the plate looked more like a lump of iron !

[jbutta1285]

@mainman2999 that is a Durafix, aluminum-zinc welding rod, and that part is most definitely aluminum. If it was Iron, it would be much darker. If you watch the video, you can actually see the parent metal start to melt a bit and you can see the molten metal from the rod pool into it. What he is doing is called brazing.

[jbutta1285]

@mainman2999 also, you don't need to explain the concepts of welding to me... I happen to be a welder.

[mainman2999]

@jbutta1285 fair enough, but i always thought brazing was joining two pieces together using a filler metal with a lower melting point? this looks more like soldering up a hole! I mean if that had been strong why not fill the hole up then tap a thread in, it looks crap just bunging the bolt in and trying to fill round it then undo it later! it looks very shoddy and would not take any kind of torque before it stripped the thread, a helicoil would work better!

[jbutta1285]

@mainman2999 it would depend on the application. If the part is not under a lot of strain and appearance doesn't really matter, this would work fine. This would make a good quick fix while you wait for the right replacement part to show up.

[xerox12345]

WTF... how about if the part cannot be taken apart then what?

[Lake61willy]

Helicoil is the only way! STI V-TapGuide by Big Gator Tools is a big help with hand tapping.

They have a new portable drill guide also. I saw them on ebay.

[123kkambiz]

I am sure from rear side it was not properly packed, you can see from front side when bolt is out of thread there is insufficient aluminium filling inside the hole,

it would have been better you would have fill more aluminium filling from backside too.

[glawood]

Looks like someone needs a Ratchet!

[iworkforme]

threads seem ok ...how about just some t tape

[12344richard]

That's about the most stupid way i seen on thread repair

[Streamliner009]

I think it's much easier to fix with Helicoil insert.

[salvor1]

That'll last... until you tighten it.

[MegaSinar]

where can i buy aluminum wire just like that you used in

[dannyhann2]

The video was done to make a point. Not too show how to make threads... Can nobody see that???

[TheNandopro]

this in my opinion is kinda half assing it solder was not meant for this kinda thing im mean it will temporaraly fix the problem but a helicoil is much better

[gomezpiro]

Cheap and not a good job !! Sorry could be better ...1

[baslundforreal]

That is a total bummer! No, I will suggest that you either have it fixed with Helicoil, Recoil og Time-sert, which all are a more durable solution than taking the engine apart and Durafixing it.

Durafixing a thread is sufficient in the field, but not really as a permanent solution, as the thread doesn't have enough clearance.

It's ok for something that is rarely taken apart, but for a part like your oil filter, it's a bad solution.

[supercharged100]

@baslundforreal next time you do this vid use sound you dunb ass

[Vortech1cobra]

i have a 2000 aprilia mille just got it and the guy that changed the oil filter last completely ruined the threads should i use this technique to repair those threads? i have tried helicoils and they did not work

[alexjalaff]

Looks like shit man

[DaBuzz92]

ale chujowo zrobione.. ale pomysłowe

[jeannebrookervin]

Fantastic.

[Schmoot104]

Probably would have just used a helicoil...

[Ducatifreak999]

@paulanfieldukox Thanks for the info i will try it.

[Ducatifreak999]

i have a paintball gun and i dont want to do that because it might melt the red thing thats inside my gun but my threads are broke i dont know how to fix them without heat please reply

[paulanfieldukox]

@Ducatifreak999 Hi bud, just a thought. Is it possible to drill out the hole slightly and tap the next size up? Or maybe drill straight through and fit a longer screw/bolt & fit a nut on the end? You didn't say what material the gun is made of? (maybe the fact I don't know s*** about paintball guns LOL) If its plastic & you really need to stick to the same size fixing try filling the hole with a filler/resin substance or maybe a hot glue gun then redrill the hole & tap it out. Hope this helps

[paulanfieldukox]

@Ducatifreak999 It you really need to make a tidy job you could get a thread repair kit that puts a coil thread down the hole. It makes foe a better/stronger repair but can start to get expensive! Maybe there's a workshop near you that would do it for you. Good luck bud

[JungleListSoldier]

pretty slick

[dharmesh111999]

can find the potable butane torch used here with brazing rods here cgi.ebay.in/ws/eBayISAPI.dll?V­iewItem&item=330478617381&ssPa­geName=STRK:MESELX:IT

[insAneTunA]

Awesome !!!

[selfrealizzed]

iwould like to be a single source for your product in India

[Prozackityzac]

cool

[1fishdreamer]

what stores is this for sale?

[lincolnpicillo]

just buy a helicoil set.

[taddies2]

@lincolnpicillo What a badge just leave them to it and stick to helicoils

[craigpetrie12]

thats half ass fix, looks ugly, weak looking too

[EBIKE100]

how long will basic aluminium threads last when a steel bolt is being repeatedly threaded into and then out of the threads?

[psirider]

@EBIKE100 not very, most engineers put helicoils in from the start since its stringer then a steed bolt on alu threads,

[roaddiablo]

Could this be used to repair the aluminum block tabs that broke off with the stator cover on my motorcycle?

[baslundforreal]

Yes, just don't squeeze the block half when fixing it. The whole part becomes so hot, that it becomes sorta "mushy", and you will very easily distort it.

[tangnatalaga]

@roaddiablo yes just watch that heat. You can put wet rag around the area that you don't want to get damaged by extreme heat.

[TheNandopro]

@roaddiablo i wouldent i would use a helicoil its way stronger

[RangieNZ]

@roaddiablo The aluminium oxide (the outside layer) has a higher melting point that the aluminium inside. So by the time the 'filler' gets to the temp for melting, the inside is liquid.... Very easy to stuff up the rest of your part.

[TheDand2009]

In my opinion you should try with Oxyweld's equipments. You will be more fast and the connections will be more stronger than traditional systems.

[baslundforreal]

Ah, ich sehe! Ja, es ist ein bisschen lang.

Gruesse.

[VWSven1]

Also ich gehe um kurz nach 21 Uhr heute zu Bett! Muss morgen wieder früh hoch!

[baslundforreal]

Gut fur dich, VWSVEN, gut fur dich.....

[VWSven1]

So weil das Video so spannend ist: Ich gehe was essen und bisl TVgucken!

[baslundforreal]

It's not me in the video, I just sell the stuff here in Scandinavia.

That bolt is apparantly a normal steel bolt, as Durafix doesn't adhere to it.

I suggest this as an emergency repair, as you won't get the correct tolerance in the thread this way.

Works fine though.

[7olusegun]

Please can I ask if Durafix 'welding' rods can satisfactorily weld or solder mild steel parts together?

Can Durafix also weld aluminium and mild steel together (i.e. aluminium-mild steel welding)?

[baslundforreal]

no, Durafix WILL NOT adhere to iron,steel or stainless!

[baslundforreal]

It works on most aluminum-alloys, but also brass and copper.

The solder used is Durafix, it melts at app. 392C, that's around 732F.

[lebammabel]

Great demo. What kind of solder is used and in what temperature it melts?

[tylerc1992charlo]

were can i get some of this stuff

[Survivalist2theEnd]

The holes are not threaded. By using that method you get threaded holes. You could fill it, drill it and tap it if you want but that looked a lot easier to me.

[baslundforreal]

You can repair threads by cleaning, heating, filling up with Durafix, and inserting a heated bolt into the hole.

Of course it's easiest to do with blind holes, and you need to drill out all of the old thread, or else the Durafix won't be able to escape, as the bolt is dropped in.

I've even made threads by drilling and tapping solid Durafix, but that's another story.

For emergency thread repair, and for permanent fixes of everything else(aluminum), it's very good.

[ackpacket]

How is that thread repair? It looks like the top part is the only successful threading, and the bolt is cricked anyways.
