cut spokes above the nipples after rim true?

I managed to get the rim fairly straight after it had wobbled all over the place, but afterwards I noticed that in the process some of the spokes were ~1-1.5 mm above their nipple heads, so I wonder if they must be cut or if it is sufficient to protect the tube with flaps? That indicates rim deformation and uneven spoke tension, problems you are unlikely to surmount so start planning for a rim or wheel. Trim the spokes back to level with the nipple head, ensure the rim liner isn't cut through and remember to remove the rubber and do that again when you next true it. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

http://sheldonbrown.com/wheelbuild.html with the felt pen.... Spokes protruding are in the short diameter side Spokes somewhat indented into their female rim threading are on the long diameter Find the most outward and inward positioned spokes....mark that place on rim breaking surface-both sides....across the felt penned circumference mark you made. Count .25 of spoke count counter and clockwise from each inward and outward point. You should now see 2 halves of an ellipse * Spokes are adjustable as a reductions of nipple turn from the most outward inward point... Start with a loosening of one turn at the most outward and a tightening of one turn at the most inward Move out to the halves point going alternately each side of the max inward outward spokes And alternately the opposite inward and outward point halves/quarters Gradually the elliptical wheel you had built will stretch into a rounder shape Checking with both spoke positions as inward outward and a new felt circumferential pen marking will indicate round or not I have a truing stand where the wheel is spun against a fixed point...I use a credit card When the wheel is rounder...adjust all spokes to equal tension or ping/blonk when plucked. Of the rim is unbent and all spokes were of equal length to begin with then you're moving toward a trued wheel. https://plus.google.com/photos/10223...761?banner=pwa IHS * 'ELLIPTICAL' is corrupotted by OEM |

Nice tool but doesn't cut flush to the nipple head like the Var design: http://velobase.com/ViewTool.aspx?ID...3973&AbsPos=39 -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Probably best to discover if the bloke has double wall rims, or not. If he does the spoke ends probably won't be a problem ... He said the spokes make a small ball beneath the rim tape. It's highly likely that in time the spokes will wear through those balls and then puncture the tube. Indeed, the bloke doesn't have double wall rims Thanks for all suggestions and in particular all the specific references to tools. I'll have to hit the dictionary and then see if the shops in the city have anything to offer. And yes, I understand that optimally you have a brand new rim with perfect length spokes. However this wheel was badly damaged. Now it is mostly straight - a lot straighter, anyway. When doing it I didn't consider the spokes but afterwards it hit me those would be a problem later on. But the spokes are most likely of the correct length to begin with. -- underground experts united http://user.it.uu.se/~embe8573 |

Sometimes a bent rim that's been straightened can fail. Cheers |
