Problem In assembling rear wheel
 

Hi everyone on this forum ,

Recently I got some of the nipples on my rear wheel damaged and I decided to change the nipples in order to be able to true the wheel properly. The wheel has 32 spokes with 3 cross pattern. Now when I lace the spokes the last set of 8 spokes appear to be too long. Even If I tighten the nipples up to the end it is still above the rim. You can see it more clearly in the pictures. Why does that happen ? What did I possibly do wrong ?

Take a pic of-
The hub showing all the holes, not just 1/2
The entire wheel, centered in the pic.
The 2 spokes on either side of the valve hole and their corresponding location on the hub. Little colored 'flags" or something to match the hole in the hub with the corresponding hole in the rim.

Most likely, you started the 1st spoke of the 2nd or 3rd set in the wrong hole.
Look at the other spokes- Do toy have a similar group that will be too short?

I think that I have done everything correct. I have followed the tutorial on Sheldon Browns website. But of course I can't be sure

No the other 3 set of spokes were neither too long nor too short I think

This is a classic issue with 1st time builds. The spokes to each flange are fine but aren't phased or sequenced correctly to match the other flange.

Numbering the spokes in the rim in sequence the even spokes go to one flange and the odd to the other, (or right/left/right...etc..). In the hub the sequence is similar, with the spokes alternating right, left back and forth across the hub.

Place a spoke or sight across the hub and where two adjacent and almost parallel spokes, ie. the circled one and it's mate to the left, and follow them down to the hub. The left spoke should go to a hole 1/2 holes to the LEFT of the one that the spoke to the right goes to. I'll venture that it doesn't.

Thanks for replies
So I have disassembled the wheel again and now can anyone say for sure where should I insert the first spoke of the left side?

WRONG! WRONG! WRONG!

Actually I agree with your statement about the patterns on the two flanges being out of sync with one another. It's the part about 1st time builds that I disagree with. Don't ask me why.

I won't ask why, but I am curious what part you disagree with. Is it that I'm wrong that it's common with noobs, or that it's also fairly common even with fairly experienced builders?

Note, that my saying it's classic for 1st time..., doesn't in any way imply that it's limited to them.

I don't assemble using the same method, so I'll simply identify a paired set of spoke holes. starting from the valve and with you facing what will become the right side of the wheel, the 1st two holes to the right (1 o'clock) I'll call nos. 1 & 2. These will be "pulling spokes, and go to opposite flanges on the right side of the hub at about 2:30 or so. The rim has offset which dictates which is to the right flange and which to the left, but the spoke closer to the valve will go to the hole in the hub one half space to the left of the other., ie. if the 1st hole is to the left flange, that spoke will be to the hole slightly to the left of it's opposite in the right.

When helping 1st timers I suggest looking at the rim 1st and seeing if the spokes moving to the right of the valve are marching right/left, or left/right. If marching right/left in the rim, they have to march right/left in the hub, so the left pulling spoke would be to the right of the right pulling spoke

You have a point. I only posted what I did because I knew it would get to you. :)

It didn't get to me, though I suspect that there's a story behind the "don't ask me why", which I politely didn't.

Sorry but I didn't understand a single thing. So where should I insert the first spoke on the left side. Please heeelp

That's a problem because I tried to be as clear as possible. The next spoke to the right in the rim is going to go into the next hole to the right in the hub, and will be a head out spoke, same as in the right flange. So if you still don't get it, it's a heads out spoke in hole 2.

I have done the same. Watch and follow along with this video and it's simple. Lacing a Rear 32 Spoke Wheel, 3 Cross | How to Build a Bicycle Wheel - YouTube
