Complete wheel rebuild

I have an old MTB wheel that's totally trashed Hub and rim are fine but it's got broken spokes and it's not true at all... If I want to try my hand at a complete rebuild, can I just replace one spoke at a time?

I'd use this as a guide:

http://www.miketechinfo.com/new-tech-wheels-tires.htm

So I'd go around one spoke at a time until I had all of the spokes replaced really loosely but evenly, then evenly tension them and follow the build up from there.

Comments? Bad idea? I could buy a new wheel but I'd rather try to fix this one while picking up a new skill.

It would actually be a lot less work to just re-lace it from scratch. You want the spokes to all be oriented as they were originally so they can bed in the impressions left from the last build.

Check out http://www.sheldonbrown.com for good instruction.

I've done it both ways and agree with waterrokcets, it would be easier, even quicker, to remove all of the spokes and rebuild the wheel with new spokes and nipples. And this would be a better way to learn wheel building. You could use measure the old spokes for length or just take them to your LBS to match lengths with new spokes. If it is a rear wheel the driveside spokes are probably shorter than the non-driveside spokes.

I haven't seen your wheel but my bet is that your rim isn't fine.

If your rim isn't true and round to begin with you'll spend a ton of time trying to pull it into line. Even if you succeed (which I doubt) the spoke tension will vary all across the board and the end result will be a crummy wheel that'll get trashed again before you know it.

True, but I was assuming that the primary purpose of this exercise was to learn wheel building. Maybe the rim could be straightened and rounded close enough before lacing the spokes.

The problem with that is a trained chimp can lace the spoke pattern. The important learning comes in the tensioning and trueing process. That's going to be hard to learn with a crappy rim.
