Wheel building questions
David L. Johnson Wrote: You probably have them already, but if not I recommend butted spokes. They make a more reliable wheel. I am a big guy (245 pounds last time I checked) will butted spokes mak that big of a strength difference in the wheel? I did not buy the ri and spokes yet. I am thinking of a Sun double walled rim with eyelet that I can get for a good price. And the spokes are 14 gauge stainles steal (non butted) as stated in the my first post. I will Also try t make a dish stick. Looks like I am able to make it from the suggestion you guys have given me. Thank you all Pet -- big Pete |

Thank you all Pete DT or Sapim 14/15 double butted spokes will make the wheel more durable, but not as stiff. Suggested Reading: "the Bicycle Wheel" by Jobst Brandt. The book is available in some library systems as well as for purchase. -- daveornee |

Thank you all Pete Dear Pete, Both thick 14 gauge spokes and thin butted spokes with 14 gauge ends and a 15 gauge middle are more than strong enough to bear the loads--they break at the ends, not in the middle. Double-butted spokes keep the ends thick to try to reduce such breaks. Their advantage is that, being thinner for most of their length, they stretch more and therefore are less likely to lose all tension (a bad thing) as they roll under the hub. When the rim flattens ever so slightly against the pavement, the spoke above it loses tension. A thick straight spoke didn't stretch as far as a thin-center-section spoke, so the thick spoke loses all tension and rattles, going out of true and breaking more often and while the thin spoke can contract that much and still have tension, which makes it likely to last longer. Think of them as rubber bands at the same tension, neither of which is going to snap in the middle, but neither of which we want to go slack. The thinner rubber band enjoys a greater range of motion.
