Matthew_Gibson Posted May 15, 2014 Report Share Posted May 15, 2014 I was wondering if anyone could give be a bit of advise/pointers. I need to somehow replace my star nut in my Neon forks. I've had two "small" star nuts pull up the steerer. It doesn't matter how far down they go,or how straight they are they only last around 4 weeks and destroy them selves. ( with correct tool too) I'm wanting to machine up a plug type insert with a thread down the middle to do away with the starnut. Interference fit if possible or tight enough so it wont spin. Or should I use epoxy to stick it in? Just wont advice before I go mental on a lathe. Sort of thing I want to make Thanks Quote Link to comment Share on other sites More sharing options...
Jake. Posted May 15, 2014 Report Share Posted May 15, 2014 Use a "medium" star nut then? 1 Quote Link to comment Share on other sites More sharing options...
Matthew_Gibson Posted May 15, 2014 Author Report Share Posted May 15, 2014 forgot to say. that doesn't work. just ended in 3 pieces Quote Link to comment Share on other sites More sharing options...
MartMini Posted May 15, 2014 Report Share Posted May 15, 2014 use a medium star nut and grind it down a bit. Especially if you leave sharp edges, they help dig into the steer tube 1 Quote Link to comment Share on other sites More sharing options...
*gentlydoesit Posted May 15, 2014 Report Share Posted May 15, 2014 Doubt you'd get interference fit to work, unless you've got a big ass press. Personally I'd just bond it, 3m panel bond would work well Quote Link to comment Share on other sites More sharing options...
trialsalot Posted May 16, 2014 Report Share Posted May 16, 2014 Bond it via heating the steerer a fair bit and cooling the plug loads. Quote Link to comment Share on other sites More sharing options...
bike_dummie Posted May 16, 2014 Report Share Posted May 16, 2014 Why not fit a headlock instead? Quote Link to comment Share on other sites More sharing options...
jack iveson Posted May 16, 2014 Report Share Posted May 16, 2014 Drill a hole in the steerer and thread it , them put a little bolt into the steerer so its pushing against the insert (use a magura bleed bolt ) Quote Link to comment Share on other sites More sharing options...
ogre Posted May 16, 2014 Report Share Posted May 16, 2014 Why not fit a headlock instead? because their heavy and hideous... another vote for grinding down a starnut to fit... 1 Quote Link to comment Share on other sites More sharing options...

Maxx Posted May 16, 2014 Report Share Posted May 16, 2014 If you destroy every star nuts you try to put in 1 month, then you're doing something wrong (incorrect size, bad installation, overclamping the bolt). Keep in mind the star nut should be "hard" to put in the steerer, but not too hard. Not too loose too. And you must tighten the headset bolt just enough in order to remove any play, you don't need to tighten it more. Quote Link to comment Share on other sites More sharing options...
*gentlydoesit Posted May 16, 2014 Report Share Posted May 16, 2014 (edited) I always had issues with starnuts on my bmx, I'm with mathew on finding somthing stronger. Bond it via heating the steerer a fair bit and cooling the plug loads. I thought this, it will work if done carfully and the insert is the bang on size.

Mark W Posted May 16, 2014 Report Share Posted May 16, 2014 I've used araldite/generic epoxy resin to hold them in before. Other alternatives would just be to make a headlock-style system? Something else to check is that your stem's clamping properly too, by the way. Clean the steerer tube/steerer clamp area, grease up the bolts, etc. Once you've set the headset preload with your top cap it shouldn't really have to do much else but just chill out up top.

J.KYDD Posted May 16, 2014 Report Share Posted May 16, 2014 Another vote for a headlock. They also help stop the forks f**king off into the distance should they snap as the base of the steerer 1 Quote Link to comment Share on other sites More sharing options...
dezmtber Posted May 16, 2014 Report Share Posted May 16, 2014 Starnuts work,and work well if there the right diameter and fitted well. Sounds like you fit them right. So try a medium ground down to size. At least try that before you bond it all together for good. Quote Link to comment Share on other sites More sharing options...
Matthew_Gibson Posted May 17, 2014 Author Report Share Posted May 17, 2014 Thanks for the input fellas. but as the steerer is not too short by 20mm. I'll get getting a new pair Monday. With a "normal" stem should be back running for next end!! as for what people said. headlock would work as the one I had (didnt really want to buy new) the threaded bit was too big for the forks and stuck out 50mm! Hope Hed doctor - too big. I would have loved one, but with having a thick steerer tube wouldn't work. Quote Link to comment Share on other sites More sharing options...
