where would i go to ask a question about pipe threading?

[joeblaze]

i think that is the term im looking for.

the 2 things screw together but the threads have worn down on the important part. i need to make those threads bigger. no shit i dont even know if it possible but it mean i might as well throw away 90 squids because of a fucked up threads that hold the battery.

this thing gets warm so that plumbing stuff is a lot of hassle couple of whacks and its fked up and i have to try and seal it again

You have 3 options really 1, you can use a tap and die set this little gadget cuts new threads on for you. Take it slow when using and put plenty of oil on.
2 you could weld a bolt in one side of the tube and a nut in the other if the tube is steel. Or if plastic very strong adhesive.
3 weld the two together if they are steel or buy a slightly bigger tube and slot them inside it and silicone it. Good luck.

Some pictures would help. Which thread has gone. The part with the external thread or the part with internal thread or both. What does the part belong too and what material is it made from. Sorry For the Spanish Inquisition

Yep sounds like a tap and die set needed BUT size matters in your tool you use,if worn down i dont think you have enough metal to rethread the old bit but can it be cut off and section below rethreaded.Can this pipe be moved closer if shortened.
Not sure if this works,if threads are long put your tap/thread chaser below and you can use something like this.

If it is pipework it is a tapered thread and you need to put thread tape on it to stop it leaking. If you have stripped the thread then thats a different thing all together. a set of dies for pipe threading is pretty expensive.
Just my thoughts

What about these thread restoring things?

Fitters at work used to use it decent stuff.

As far as i know helicoils usually went into spark plug holes or holes in a block when pulled/over tightened.The bit at the bottom breaks off when the bolt makes contact with it and the barb bites into outer area to hold it in place.We have helicoils and solid seats for inserting depending on job.

Need pictures @joeblaze!

Yes lets spam him @joeblaze

Helicoils are good in lots of cases, But they are a little specialised. You need a kit which includes the fitting tool, and a collection of the coil incerts. On top of that you need the tap for whichever size of helicoil you are going to fit. Plus the drill to drill out the hole to suit the tap. But you tend to use them only in special needs or a last resorts. Very expensive for a one off application.
Just my thoughts

Need pics @joeblaze mate.
Im not to far away from you, i could get it milled out for you.
But need bit more info mucker.

Im heading down to HMS caroline during the week for bits and pieces that needs done. So might be able to get you on way down.
(if at all i can get whats required)

Just a heads up for anyone that has never used the Helicoils - Use a thread lock adhesive when fitting the coil and allow to set.

A very good point, These things are Terrible for coming loose if you ever undo the screw. They pick up and the next thing is you have a bigger hole to contend with. Drilling out, plugging and welding are the best option then remanufacture the hole. That is if you have the time or the space in the metal. I am not to sure about thread lock if it was on a cylinder head though. but then again i have never done one there so i dont know if thats suitable.

 

[piggy13]

Yes they do, especially if have to undo the screws on a fairly regular basis.....one offs no need ?, but I still would use it.
I think loctite do one for over 450 Fahrenheit, not sure though, is that enough for a cylinder head ?

 

[joeblaze]

its me vape guys. me fishing vape its a blow. of course its the thread on the oven bit. i wasn't charging using usb. i had a charger with 4 batterys to do the day. so it was open more alot. i have the charger 4 spare batterys and a glass bubble specially for this. no good otherwise

 

[piggy13]

Just buy some fags.....sod the vape...or buy a new one, me thinking this was something a bit more serious which involved loads of dosh...

 

[joeblaze]

its not an ecig it for me weed man, bad lungs cant toke even a bong it my only option. with all the extras i have for this is a couple hundred ffs.

it is serious lol

 

[piggy13]

Just buy another or return the one you have as faulty ? As you say you already have the extra's....so it's only 90 squids.......
How much does the weed cost ?
Not that I want any by the way, just curious.

Threads on aluminium like that never last long, Maglite torches >20 years ago come to mind, solder suckers too .

That's so thin it can't be rethreaded.

You could maybe find something to seal it with and leave it sealed and charge using USB. Would that work?

I'd probably try a thin bit of copper wire, or tinned copper, from a stranded piece of wire. From a bit of 7/0.2 or similar. Then wrap it into the thread groove in a way that it won't unravel and screw it together. Or a strip of tinfoil wrapped round it and pressed down into the groove.
