Threading forks

no-one has even asked if the steerer tube is steel or ally..

personally, I think it's a fucking idiotic thing to do.

just use a proper stem and ride the fucker!

you can safely extend a thread but only say like an inch maximum and not on chromed steerers. But it really kills the die on the thread cutter which is made purely for chasing them threads

as for cutting a thread into ahead steered - No. unless you have an industial big machine thread cutter.....i have seen fork at which someone was trying to extend the threads more than say 1 cm and he managed to make it too deep so the threaded area was like a hourglass thick at the top narrower at the middle and thick on the end again......result...forks fukked....unless you take it to a framebuilder to have the old steerer debrazed and brazed on a new one

Steel fork steer, tool is not a problem, my Dad has an industrial lathe that will turn the thread easily, or I would get Mercian to do it. I must be a madman, I just plain don't like ahead.

I will have a hunt for some threaded forks to suit.

just use the nasty looking ahead stem and ride the fucker!

Fully intend to.

you might well have a industrial lathe, but how would you hold the fork ends ?????

Fork handles, obnov...

Not sure, I have not used a lathe for years, but I could see that being a problem. I guess when frame builders do it the steering is threaded before it is brazed onto the fork.

broken 777 - Are you talking about me? This sounds like my story, double plate crown forks purchased from BLB and on the basis of this or similar experience I would definitely endorse rpm's advice

haha

There is different dies and taps for cutting or chasing threads, using a chasing die to cut threads will make a mess of the die and the forks, make sure you have the right one. As long as you use the right tools and techniques, and the forks are suitable then there is no problem cutting threads on it. If your in doubt either get new forks or get Mercian to do it, they will have done it before loads of times.

hi,
before i start i should say that i live in the north west (like Preston north west).

i have a pair of forks with a 1 inch steerer and need to extend the thread downwards by about 5 cm. several bike shops here don't seem to keen to help me out cutting a new thread (in fact the forks are at one shop - and he "will do it when i get around to it" - 2 weeks and counting...)

anyone know if any shops in manchester (or other NW towns) have the tools and would do it for me?
craig?

cheers, chris.

Have you thought about using a threadless headset instead?

what type of stem does that limit me to?
for me the aesthetics of this bike are important and i want to go fully old school - im not sure it would look too good without a quill stem.

okie dokes, you need to stick with the threaded then.

bad thread?

Give it a chance, we're only 6 posts in.

Has anyone had this done recently. i have some 1 inch carbon forks with a steel steerer tube and i need them threaded. any idea who can do this in london. cheers

bikefix

Wouldn't a threaded steerer be rolled instead of cut anyway?
Most bolts are rolled.

Nowhere I spoke to would do it. That includes every frame builder on the list and all the shops in london or elsewhere that you think might. I spoke to about 50 places in total and not one would do it, not much help. Sorry

Would anywhere replace the steerer? (this would knacker the paint obviously)

yeah i was just in bikefix and they wont do i guess my search for a 1 " carbon fork goes on

I had some done at Argos a month ago, give us a call. Steerer swop, threaded to unthreaded, that is. Don't see why they would go the other way?
S.

All,

have bought some old forks off here and found I need another 25mm of thread on them. Can anyone help or suggest a good place to do this? My LBS is Mosquito so don't trust them for a second. Something nearish N1 would be good also if I'm being fussy...

Assuming they are 1" and the bit you want threaded is not chromed I can do it for you... but in SE1 not N1...
