Just copying this over from a thread I did in TF. May not be "Beginners" stuff, so if mods wanna move it to somewhere else, go ahead...
Building wheels is pretty simple and straight forward when you know what you're doing. People seem to assume there's some sort of black magic involved with building wheels and adjusting spokes and so on, but there really isn't. To stop people wasting their time and money sending their wheels to people to build and paying £10-20 for a job they could easily do themselves, here's a wheel building guide.

This is my old wheel. The spokes, as you can see in the top pic, were a little too long. Therefore, you get what happened in the bottom pic. Many times. Not ideal.

As a result of this, I decided I'd get some new spokes (not some 5-year-old spokes that came on an Onza complete that are 5mm too long...), and re-lace my wheel. If you've got all new bits, it's super easy, if you're reusing the same hub and/or rim it takes a bit longer to de-lace it, but just work around each spoke loosening off the nipples, then take the hub out when they're all off.

Anyway, you will need:

http://img89.imageshack.us/img89/9437/pic2whatyouneediz1.jpg

The right amount of spokes + nipples, a hub, a rim, a GOOD spoke key, some sort of screwdriver (using the one on my Specialized EMT tool here) and a blob of grease/some oil. This is the grease I used:

http://www.trials-forum.co.uk/forum/style_images/modernv2/d21_air_error.gifhttp://img74.imageshack.us/img74/581/pic3blobofgreaseha0.jpg

Fluoro. Nice.

Just to clarify: I am lacing this wheel 36 hole, 4 cross. This guide will cover any amount of spoke builds with any amount of crosses, you just adapt it slightly.

The grease or oil is to put on the spoke threads to make sure that the nipple tightens the spoke up nicely and evenly, instead of sticking at some points and twisting the spoke instead of moving down the thread.

http://img74.imageshack.us/img74/5671/pic4wipespokepg5.jpg

Lightly wipe the spoke in the grease or put on a few drops of oil. You don't need much, just a little to get it moving nicely.

Then, you need to insert the spoke. Place the hub so the drive side is facing up towards you. For the first spokes on each side, you place them through so the head of the spoke is on the OUTSIDE of the hub flange. It doesn't matter which hole, especially if it's a new hub.

http://img89.imageshack.us/img89/3189/pic6correctspokeholefe9.jpg

Look at your rim. To make sure you have room to slip the valve of a pump in to access the valve, you need to put this first spoke in to the right side of the valve hole as you look at the rim, thus:

http://img89.imageshack.us/img89/3530/pic7spokeinsertedgt1.jpg

Having slide the spoke through the spoke hole, attach the nipple to the spoke:

http://img156.imageshack.us/img156/166/pic8tweaknippledp7.jpg

For mine, I did 3 full turns of it just using my hand, although you can bring the screwdriver into the equation now if you can be arsed. However many turns you do, make sure you do the same amount on every spoke. I cannot emphasize that enough - make sure it's the same amount on all of them. Also, don't go nuts and put too much tension on. When you come to twisting the hub and lacing the last set of spokes in on each side, it will be a complete bitch, so don't put too much on too soon. If you're having trouble remembering which way to turn the nipple, just make a thumbs down sign with your RIGHT hand. The thumb points in the direction the nipple needs to go to tighten up the spoke, and your fingers curl away in the direction you need to turn the spoke (which is clockwise as you look down). You can use this right hand rule though to easily recall which way to turn it when you're trueing your wheel at a later stage.

http://img74.imageshack.us/img74/8641/pic9gooneholerightss0.jpg

Now we need to insert the next spoke. As you look down at your hub, miss out a hole to the RIGHT of the first spoke. The second spoke needs to have a single hole between it and the first spoke. Insert the second spoke so it's head-out again.

http://img156.imageshack.us/img156/9404/pic10missout3holesci7.jpg

Counting 3 holes to the right of your first spoke in the rim, place the spoke in. You need to leave one hole for each of the other groups of spokes: the non-drive head-out spoke, the drive head-in spoke and the non-drive head-in spoke. Therefore, you leave out 3 holes and then place your new spoke into the correct hole.

Attach the nipple with the same amount of turns you did to the first (so again, for me that was 3 full turns).

http://img89.imageshack.us/img89/1516/pic11finisheddrivesidepi9.jpg

Finished drive-side, having followed the same routine for all the rest of them.

http://img89.imageshack.us/img89/9879/pic12flipwheeloveroj8.jpg

Flip the wheel over.

http://img89.imageshack.us/img89/4681/pic13rightholewb6.jpg

We now need to do the head-out spokes on the non-drive side. As you can see, I placed two spokes in to demonstrate which hole you need. The drive-side spoke there is the first one I put in, aka the one next to the valve. The spoke holes are slightly offset to the drive side, so you can lace it properly. You want to choose the hole (highlighted by the green spoke) that is slightly to the left of the drive side spoke.

http://img89.imageshack.us/img89/623/pic14leftholetofirstspokepa9.jpg

Having fired that spoke into the correct hole with the head to the outside of the flange, you then place the spoke into the spoke hole to the left (that's AWAY from the valve hole) of the first spoke.

http://img89.imageshack.us/img89/9587/pic15insertsecondholeoneoverdz6.jpg

Insert the second spoke missing out a hole to the left of the first non-drive spoke, head-out again.

http://img74.imageshack.us/img74/1153/pic16insertoneholetoleftofsecondspokeyn8.jpg

This next spoke goes in to the first hole to the left of the second drive-side spoke.

Repeat until that side's done:

http://img74.imageshack.us/img74/4036/pic17nondrivedonexc3.jpg

Flip over the wheel.

http://img156.imageshack.us/img156/252/pic18flippedoverwheelbk6.jpg

We now have to twist the hub so that we can lace in the crossing spokes. Grip the rim with one hand (or lay it on your lap) and grab the sprocket/cassette body/anything you can get a hold on. You need to twist the hub so that the spokes next to the valve hole point away. This means spinning it clockwise. You'll know when you've spun it enough because the nipples will be tight-ish against the rim, as you can see in the pic here:

http://img89.imageshack.us/img89/3923/pic19wheeltwisteden0.jpg

We now need to start installing the head-in spokes. Slide the first one into the one of the empty holes between the head-out spokes on the drive-side.

http://img74.imageshack.us/img74/8994/pic20drivesidefirstoutwardspokero2.jpg

This is where you can check if you've spun the hub correctly. To make it easier, lay this new spoke across the other spokes, as shown below.

http://img89.imageshack.us/img89/9264/pic21drivesidecrossspokejs7.jpg

This is a FOUR CROSS build. As you can see, it crosses one spoke inside the flange, one spoke just after, another just after that, then the last one further out. However, if we laced it so it was going over all the spokes, nothing good would happen. You need to under-lace the last spoke, e.g.:

http://img89.imageshack.us/img89/6120/pic22spokeunderlacedqn6.jpg

If you are doing a 3 cross wheel, your hub won't have spun as far round as my 4 cross wheel did, and you will only cross over 3 holes. You still underlace the outside crossed spoke which will be the third spoke for you. The same goes for 2 cross, or indeed 5 cross.

http://img156.imageshack.us/img156/4541/pic23newspokenewholeap3.jpg

You place this newly laced drive-side spoke into the next hole to the right of each pair of spokes you have currently in the rim. It'll also be pretty obvious which hole to go into 'cos it'll only reach one of the two of each pair of empty holes, but again, the first hole to the right of each currently installed pair of spokes.

As before, just repeat until you've done all the necessary drive-side spokes.

http://img74.imageshack.us/img74/6552/pic24drivesidedonetx2.jpg

Ta-daaaaaaaaa.

You will notice on this pic that the spokes look like spaghetti, and indeed my hub appears to be in on the piss. Do not worry about this if your's is like this too; when you install the last set of spokes and you rack up the tension, the hub will naturally be pulled so it is straight and true, unless you have majorly f**ked up the build.

Flip your hub over so we can do the non-drive head-in spokes.

Insert the spoke like you did with the head-in drive side spoke, and lace it similarly to how you had to lace the last set of drive-side spokes:

http://img156.imageshack.us/img156/7833/pic25newnondrivelacedinlv2.jpg

Now the hub's being pulled in different directions, it may well be that the spokes aren't all sticking up through the rim nicely, and as such you'll need to possibly use the screwdriver to reach the tops of the nipples so you can tighten them up correctly:

http://img156.imageshack.us/img156/1452/pic26screwdriverturnzn7.jpg

Continue doing all the last set of spokes.

http://img89.imageshack.us/img89/9619/pic27wheelbuiltplusspokepatterneg1.jpg

This is what my wheel looked like at this stage. Again, notice how the spokes are all wobbly and weird, and the hub's still not perfectly aligned - this isn't a bad thing. As you tighten the spokes up, it WILL be pulled right, so don't worry about it.

You now need to add tension to each spoke. This is the most time consuming part of the build (unless you've had to de-lace an old wheel, in which case, it's the joint most time consuming part of the build http://www.trials-forum.co.uk/forum/style_emoticons/default/tongue.gif). Get your good quality spoke key (hint hint - a good spoke key is worth it's weight in gold, which is generally a pretty accurate statement. Either way, if you aren't rounding off your nipples all the time or it's super tight to fit on, you'll build the wheel a load faster and more accurately). This is the one I used:

http://img156.imageshack.us/img156/2930/pic28makesurethespokekeyfitshf5.jpg

It's just a triangular Park Tools spoke key. Choose the hole that fits best.

You now need to start off at an easily rememberable point (e.g. the valve hole or the join of the rim) and work around each spoke, adding tension as you go. Make sure you add the same amount of tension to each spoke. If you do this, your wheel will require very little in the way of adjustment afterwards.

I added 3 full turns to each spoke as I went around. In the end, I ended up (including the first 3 full turns I originally did on the nipples) doing 5 sets of 3 full turns, and then 1 set of 2 full turns, then 2 sets of one full turn each time just to get to the final, correct tension. This will vary depending on build, spokes, nipples, etc., so by no means is 19 turns the optimum amount. However, don't try and add all the tension at once because it'll be hard to judge when the tension is correct, simply because as you tighten each spoke, it is pulling the hub and other spokes laced over it to some extent, so turning the first spoke til you can't turn it any more may not be the best idea. Slow and steady wins the race.

Continue adding tension until you can feel the spoke key is pretty hard to turn. If you have a tensionometer (or whatever they're called http://www.trials-forum.co.uk/forum/style_emoticons/default/tongue.gif) you can use that to see if the tension is correct, but for most people just squeezing the X's of the cross over spokes will usually let you feel how you're coming along. Getting it so the spokes are firm but not rock solid is generally the best bet. Too loose isn't great, but neither is too tight. You'll learn over time how much tension you need.

Every now and again, it's also best to de-stress your wheel. Lay the wheel down on it's side, so the axle is touching the floor. Then, using one hand of opposing sides of the rim, press down. If you haven't used much oil (or any at all), you may hear the spokes pop and ping as they settle. When the nipples don't spin nicely and twist the spoke, it means they don't have the same amount of tension as others, and when you de-stress the wheel it removes the twists from the spokes.

Because I'd lubed the spokes up and been very careful when I added tension, my wheel ended up needing virtually no adjustment or trueing at all. The hub was centred, it was almost completely true, and there was very little up and down play. With dishing on some wheels, you may need to go over it and make sure the rim is properly located, BUT with the correct length spokes it should pull across of it's own accord.

Anyways, after doing all of the above you'll have built a wheel. Woo. Here is a blurry pic of mine:

http://img156.imageshack.us/img156/9155/pic29hereisablurrypicofmywheelhx1.jpg

Like I said - this guide covers all regular ways of crossing spokes (e.g. 2x, 3x, 4x, 5x) and all amounts of spokes (e.g. 28, 32, 36, 40, 48, etc.), so just adapt the technique to suit your needs.

It sounds tech when you read it, but when you're building it starts to make sense, and once you've done one or two builds you'll know it off by heart.

Just give it a go http://www.trials-forum.co.uk/forum/style_emoticons/default/thumbsupanim.gif

EDIT: I've probably left something out or whatever, so if you can see I've done anything blatantly wrong just post below...

I hate lacing rims with a passion.
When I was in school for motorcycle mechanics my 1st year I spent majority of my days lacing up dirt bike rims.
I never want to lace a rim again!
Motorcycle or bicycle.

BTW- that guy did a fantastic job with that how-to. Much respect indeed.

I htink I'm going to try building up my first wheel hen it comes in. if it sucks, somebody else can do it.

thanks for the tut

For those interested, look up The Bicycle Wheel by Jobst Brandt. The book has got some good empirically backed up theorys behind a wheel and a good wheel build.

Another way to 'de-stress' or 'stress relieve' the wheel is to grab the most parrallel spokes on one side with one hand and grab the closest set of parrallel spokes on the other side with your other hand and squeeze vigorously as hard as you can. Just work your way around the wheel. Yet another way is to lay the wheel down on the floor and step on the spokes (only if your light). In any case, make sure sufficient force is applied.

In my experience, perhaps its because I am dumb :Wavey:, I find it is easy to use the wrong wrench hole with a multi-size spoke wrench. If you use the wrong size one too many times, you might strip the nipple.

Correct me if im wrong. When he starts with the first spoke he puts it in the right flange on the hub and then he puts it in a hole on the left side of the rim. Should not spokes from the right flange go to holes that are drilled on the right side of the rim, you know the holes in the rim are not drilled in a straight line. They are drilled left, right, left, right and on.

I de-stress spokes alot when I build wheels. Makes the settleling in process much quicker.

When I stick the spoke in the hub, I notice which way it will be bending or crossing and give it a gentle nudge in that direction to speed along the process.

Pretty much seating in the spokes in the general diretion they will be bending. I do this at each cross. When the wheel is laced up and tensioned, I will put it on its side and stand on the spokes to de-stress it even more.

Rule:
If the hole to the right of the valve hole is lower than the one to the left, hold the hub with the drive side down.

This will give you room later on to put a pump on. Also, the pushing spokes are on the outside, and pulling spokes are on the inside.

I use a technique that allows you to lace a wheel quicker and easier than the 1 spoke at a time method.

I lace the whole drive side wheel and do the crosses while inserting 2 spokes at a time skipping every other whole on the rim. If you follow the exsisting pattern on the hub it will make it much easier the 1st time. I will try to post some pics in a few days. I am actually building up a new set of wheels. This will make it alot earier to comprehend what I do.

I've been doing this method for about 8 years now. Prior to that I laced wheels like described on this thread for about 4 years. Its a PITA that way in my opinion.

I can lace a wheel in 5-10 mins my way.

I always found that way you had to bend spokes too much to get it around others. I lace driveside with heads out, non-drive with heads out, drive with heads in, and then non with heads in. I can lace that in about 5-10 minutes as well, but have had a lot of practice over the years, so from starting to lace to tensioned I can do it in 15-20 minutes for a normal wheel. Knew of a guy that used to work at Mavic did it that way in about 20 minutes/wheel... but blindfolded.

Will this work with any rim and hub? I'm going to be lacing a rhyno lite rim with a shimono xt hub, the rim is much skinnier. I just want to know if these are the right directions to follow for my set up.
Thanks
