Adam Griffiths Posted April 17, 2009 Report Share Posted April 17, 2009 you may be able to weld the joint back but it would look ugly. Quote Link to comment Share on other sites More sharing options...
pogo Posted April 17, 2009 Report Share Posted April 17, 2009 You could weld it from the inside which wouldnt be ugly. Quote Link to comment Share on other sites More sharing options...
BigAl Posted April 17, 2009 Report Share Posted April 17, 2009 (edited) Personally, I wouldn't wast time grinding it, if you think it's going to snap soon, I feel it would be better for you to just buy a new rim..www.tartybikes.co.uk is a good site as you probably know, good stuff there, if your buying A new rim though, you will more then likely have to buy new spokes as you shouldn't really use the same spokes twice.. I don't know why, does anybody know why?To answer your question, I don't personally think it will effect it, but it depends how much damage it has at the moment.Edit: Perhaps post some pictures up, it would help you more and be easier for me and other people to help you .Alex.

Sam F Posted April 17, 2009 Report Share Posted April 17, 2009 Reason not to use same spokes twice is that they become stretched from the first build then after you build it again they stretch some more therefore making the wheel build weak.

Ali C Posted April 18, 2009 Report Share Posted April 18, 2009 its fine to re-use spokes, as soon as you de-build a wheel, the spokes go back to their origional length. If they stayed stretched then your spokes would need constantly tightening from when you built the first wheel.as regards to the splitting rim, are you sure thats just not down to the spokes beeing loose at the join? Its not uncommon for there to be a gap in new rim, but when you build the wheel, it pulls the gap together.Grinding it won't weaken it either, it only takes off a tiny amount off the rim, it more kinda moves it around rather than removes it altogether.

Muel Posted April 18, 2009 Report Share Posted April 18, 2009 The risk isn't in them stretching, it's in them work hardening, (or so I believe). Because they've been really tight for ages, then you release all the pressure and put it back on when you rebuild the wheel, they snap more easily because they're slightly more brittle than before.As far as I'm aware that's the case anyway.

Ali C Posted April 18, 2009 Report Share Posted April 18, 2009 that can be the case, but less so with good quality spokes. Quote Link to comment Share on other sites More sharing options...
