Rob1 Has anyone always fixed a pair of forks where the thread has been stripped ? Logged 750Rush Outset of all, have you tried a spacer before thiniing of repairing the stripped thread? A 5mm spacer may be sufficient. Failing that, metal epoxy tin can be uesd to re-build the stripped surface area and then information technology tin can be re-threaded. the difficulty will exist finding someone who can re-thread to 1" as it is quite a large thread. Logged Anything tin be stock-still. I personally wouldn't touch metal epoxy. Defiantly not on a pair of forks. The all-time thing to do is to accept them to an engineering store and accept them automobile the head tube out of the legs. So have a new caput tube fabricated upwards and welded in place. Or remove one from another gear up of fork. And have that welded in identify. Merely cheque the headtube is the right length first. This may sound a lot of piece of work. Only if they are a rare set of forks then it's worth getting it done properly. Logged Or go to a decent welder and have him fill weld over the afflicted area and and then have then re-threaded; Park Tools practise a thread kit for re-borer threads on forks so a decent bike shop that uses Park tools should exist able to do the repair for yous. Logged Amend to crash and burn than fade away Logged the damaged part could be welded upward and the remachined,however this would exist difficult to do as the steerer needs to be held in the chuck. Hence the fork legs must go INSIDE the chuck and down the lathe spindle,and so that work can be washed on the threaded portion sticking out You need to discover a Large lathe that will allow the fork leg to go downward the spindle welding in a new steerer may be the best option Logged Logged Amend to crash and burn than fade away Rob1 Hither`s a picture: Whether they are rare or not , I`one thousand sure one of you guys will know ; I think they are from 83-84 from a Hutch Skillful . Logged Logged doctor-46 looks like there's plenty of thread to a higher place to attempt the spacer proposition past 750 rush. Logged looks similar to the impairment i had on mine. are you coming on the london ride? if i go my tool back off of andy il bring it with me Logged Personally I would become for removing the old steerer tube and welding a new 1 in place which I could do myself and so would toll me pennies in gas and a filler rod. I'm sure someone on here has an old set of forks they may donate to the cause if you lot go downwardly that path. It may exist cheaper to only look for a replacement fork though. Logged Personally I would go for removing the old steerer tube and welding a new one in place which I could do myself so would cost me pennies in gas and a filler rod. I'm sure someone on here has an old set of forks they may donate to the cause if you go downward that path. It may be cheaper to merely await for a replacement fork though. Wow, that has to exist the most extreme solution; surely if you are handy with a welder and so filler weld over the existing threads and retapping the thread has to exist the nigh toll effective and Least intrusive way of repairing them?  Hundreds of bike shops practice that kind of repair (I know nosotros used to at Heff's Bike Store), replacing the steerer tube I suspect would inappreciably ever be washed unless information technology was bent or cracked in some way; surely?

I'm certain someone on here has an old set of forks they may donate to the crusade if you go downward that path. It may exist cheaper to simply look for a replacement fork though. Wow, that has to be the well-nigh extreme solution; surely if you are handy with a welder and so filler weld over the existing threads and retapping the thread has to be the most toll effective and LEAST intrusive style of repairing them?  Hundreds of bicycle shops do that kind of repair (I know we used to at Heff'south Wheel Shop), replacing the steerer tube I suspect would hardly ever be done unless information technology was bent or croaky in some way; surely? +1.  Well said that homo... Logged Its the cheapest method for me personally and I could do the piece of work myself. Logged one way is to find a gear up of donor forks and cut off top section and weld in new piece,simply make sure you do the join nearly the lesser or yous will struggle getting a stem in here's a pair i extended the steer tube past one" Logged British race frames and race wearable wanted Good heads up on the stem insertertion if I e'er have to do this, it hadn't crossed my mind that. Logged dan-dare i manner is to find a ready of donor forks and cutting off tiptop section and weld in new piece,just make sure you do the join almost the lesser or you will struggle getting a stem in here's a pair i extended the steer tube by 1" If your cut of the tube and welding is precise, and then you volition non have a problem with the stem; even if the joint is just beneath the threads. Logged 1 way is to find a set of donor forks and cutting off top section and weld in new slice,but make sure you practice the join near the lesser or you volition struggle getting a stem in here'southward a pair i extended the steer tube past 1" If your cutting of the tube and welding is precise, then y'all will non have a problem with the stem; even if the joint is simply beneath the threads. Think Phil has put a splicer tube in there Logged dan if they are going to be riden on i would put a shim inside fork tube where weld is for actress strength Logged British race frames and race wear wanted dan-dare dan if they are going to be riden on i would put a shim inside fork tube where weld is for actress strength you lot may clag a shim in in that location, just a good tig weld below the threads will be more than than sufficient for the fork to exist thrashed....
