thread weld

[taffy]

hi to all, yes me again with another problem i have made for myself, my @ 99 front Axel locking threads was times four but now only three, i want to try and put a nut on the thread and weld it in place so i can withdraw the rest of it,
but got no welding gear i am thinking of using a thread lock or liquid metal or what ever they are called does anyone no which one would be strong enuf to do this job. thanks in advance all you very nice people.

If you have room, you could stick two nuts on it, tighten them against each other and then try and withdraw it by turning the lower one.

Assuming you have sheared the bolt and that it is very tight in the thread, I would suggest doing this, then using a blowtorch to heat the stud up (get the stud really hot) to try and free it off before trying to turn and withdraw it.

Hope this is of use

thanks for your reply wigs, the two nuts is a good idea but i only have enuf thread to put one nut on and i am heating and cooling with a pan of hot water and my camping stove under it and keep the fork leg in the pan then spray plus gas and cool again,
i will be looking to secure one nut on the thread with a good bonding ability and pray this gets me out of sh-t.

You could use a stud exctractor.

Or, if you have access to a drill and some drill bits (HSS is best, small ones too, like 1.5/2mm) you could (and this is a bit of a long shot coz I've never tried it on a small stud):

- Put the nut on
- Drill through one of the flats in the nut, through the stud and out the opposite flat
- Pin the nut to the stud
- Undo the stud

If you were desperate you could snap the drill in the stud once its passed through to act as the pin.

Finally, if you can, I'd use the flame from the camping stove rather than hot water as you'll only ever get 100 degrees C from the water. You'll know if you get it hot enough coz you usually hear a crack/popping noise as it releases.

Failing that ride very slowly to the next garage (if possible).

Good luck

Had exactly the same problem with my Alp a few weeks back and I also thought about sticking a nut on but theres no need.

I just heated up the stud with a blow torch and got some flatjaw molegrips and slowly worked it free. That was all that was required. Yep, I was surprised too...and very relieved! Molegrips have their uses!

thanks for that yen, i was thinking of that, do you no if these threads are fixed in the fork with any thread locking compound cos if they are then surely the extractor tool will just break it further down i could do that myself without buying a tool to do it, how do you ease them locking compounds so you can just unscrew a bit easier.

cut the nut in half and then use it as a locknut that will get it off (as you say you only have enough room for one nut).

camping stove as a blow torch i do like that idea, the boiling point of the water and the flame will get it hotter good thinking i would love to hear that cracking and popping sound but can i take the fork clamp area up to that heat without melting the stud and will it affect the fork oil or seals, will be buying flat mole grips tomorrow cos the curved ones i got just twist slip and kill any job like this for me as i found out.

Just had a look at my bike.

Fork components/internals etc should be ok as the forks are huge compared to the stud and will act as a heat sink dispersing the heat you put in.

From a cosmetic point of view, when you apply the heat, apply it to the STUD ONLY and not the surrounding areas (this will not be easy using a camping stove) as I think the forks are laquered and if you blast them with a flame it may peel/burn off, remove the speedo drive too.
