starting with the 'key spoke' how do i lace a 24h wheel for a 1x pattern? i'm using Sheldon's
page as a guide, but it uses 3x as an example. Do i skip just one hole on the rim after the
key spoke? many thanks for any help anyone can give!!
Maybe its b/c I dont do much wheelbuilding, but how do you only cross one spoke?
When making a wheel, please to remember to always go 4 holes when threading spoke on one side of flange. Put spokes in, then turn hub. Next, thread spokes on other side, in opposite direction. After, go back to first side, and put spokes through other side of first flange, crossing spoke on last meeting only.
Why 1x? To save weight? Are you a professional racer? Or just the occasional racer? 1X will not save you more than about 2 grams per wheel, but it will cost you in wheel durability. You would be better off losing body fat or training harder than to worry about 2 grams of wheel weight. Go with the 3x and save yourself the hassle of wheel trouble.
Not following the wheel trouble portion. Been running a set of tubulars that are radial front, radial non-drive rear w/1x on the drive side. Zero problems with durability and truing. These are 32h wheels. I assume from the poster that he/she is using a 24h rim that is either for a deep section rim or a set of 650c wheels. Either way there is a lot less stress on either due to the shorter spokes.
Hammering a guy about losing weight and training harder instead is a <bit> off topic from the original question. Should this be a requirment? Does your answer change if you found out he is 140 pounds and rides 500mi a week? Probably not.
In answer to the original question, think radial lacing and then take those two spokes and cross them over one another. You will be left with a hole between them which will be filled by the opposing side spoke.
Good luck and let us know how it turns out.

Many thanks for the help. It was well past midnight when i started this project and all i had were
the 3x patterns to go by, i ended up guessing and pretty much got it right, turns out that most
people lace all the spokes 'heads in'/'heads out'--definately looks better. i alternated mine, it
built up fine--no probs at all.
The reason i'm lacing 1x is because i had to replace the hub and couldn't afford new spokes
and rim, so the only pattern that could use what i have is 1x.
i know it's not recommended, but the wheel is only 7 months and didn't have many miles on it.
originally, it was 24h radial and sure as sh*t, the flange snapped, might happen
again, since i'm using a 36h hub--skipping 6 holes per side, as i said, built up fine
and has made it's maiden voyage without incident. Cross my..um, fingers..
And to the person who whines about saving two grams... just wait till you mature
and start to grow hair on your chest--you'll need to offset that additional weight
somehow!! Bahhahahahaha... :) Yeah, i could lose some weight--so could my bike.
I do not use radial lacing on either wheel, because it overstresses the hub flanges. One-cross is not much better. For my money, nothing beats 32 or 36 spokes, in a conventional 3X pattern. It is basic physics -- the way to enhance a wheel's strength-to-weight ratio is to INCREASE the spoke count. On a rear wheel, the higher the spoke cross index, the closer the torque spokes lie to tangential to the rim.

I was racing bikes before you were a twinkle in your dads eye! I'm 50, so not having any hair not on my chest is not the problem its on the head where the problem lies! Actually what really happens is when your hair recedes from the head it gets sucked back through the skull and comes in your ears, nose, chest and wherever you don't want it. I'm sorry about the weight loss thing, I was referring to losing 2 grams of body weight and you would make up for the weight gain in the wheels, but I failed to communicate that properly. If you had explained more detail abouut why you needed to go 1x then this old fart would not have bothered writing anything. See what trouble you caused now?

i gotta defend myself--i'm not dumb, just broke!! :) i was able to e-bay
a replacement hub for $15 and hey, my time's worth nuthin'!! :)
i'd gladly buy a new hub, rim and spokes and lace 3x but everyplace i
went they wanted "*money*"
So my next venture--i'm 34, is a scheme to somehow convert
hair into cash that way, by the time i'm 70........ :)

Even when in the year 1962 and I was a poor junior racer, I would not ever consider riding such a bastard wheel.
