I saw on a video a drill bit to tighten the spokes to an uniform tension but cant find it any where?? any ideas? and where can I buy it??

I once watched a guy use some kind of cordless screwdriver to pull up the spokes. I kind of don't think its a short cut that I'd want to use.

Almost anyone can get a wheel pretty true from side to side, its the up and down that's tricky. The key to me for obtaining up and down trueness is at the pull up stage of building the wheel. I think I have better control when I use one of those Z-shape screwdriver things to pull up the spokes.

Factory built wheels are cheap. I don't see any reason to hand build one unless you are committed to doing the absolute best job you can.

They have a couple different tools to do the job - some for the drill and others by hand. Not sure from whom you'd actually buy the tool you decided on, but at least you'll know the specs and PN of the one you want and could order it. I'll use a chordless with a standard to -unthread_ the nipples, but I screw them on by hand to keep track of the "starting position".

This concept will not work. Picture tightening the first spoke to "proper tension" assuming you know what that is, since you have to have some flexibility as you true the wheel. The wheel will be way out of whack at this point as one spoke is tight and the rest loose. Then, when you bring the next spoke up, more of the same. The tension in each spoke affects the tension in the rest, so as you tighten subsequent spokes to the "right" tension, the earlier ones will be tightened further. Ignoring the fact that such a device probably can't get the tension close enough both due to mechanical tolerances and the fact that you are trying to measure spoke tension via the torque on a thread, it won't work anyway. This is a false short cut to building a good wheel. Don't waste your time.

SO I guess is back to the provent way!! thanks guys

Your assumption that any drill bit type of nipple device won't work is flawed. However, your logic of such a tension device is correct. DT Swiss makes a unit that is used in a drill but relies on a preset stop that only threads the nipple on to a certain point. As the spoke end comes through the nipple it kicks the bit out of the slot. The device relies on spoke/nipple position, not tension. This quickly gets all nipples threaded the same amount of turns onto the sopkes.

They retail for around $40 and look pretty slick, but I have no personal experience with using them.
Just use a nipple driverpmf

First off, I assume you're building your own wheels because you like to, not because you think you're saving much money because you won't be.

Building wheels is fun and rewarding, but its something that takes time and patience. I've used screw drivers and nipple drivers to tighten spokes. Either works fine. A nipple driver is a bit easier to work with. The key to doing this is to slowely go around the wheel gradually tightening each spoke in small, equal increments. Flexing the spokes with your hands near the end to relieve tension is also important. Using something like Spoke Prep is also worth it (oil works well to although I like spoke prep better). If you immediately tighten one spoke all the way, you'll screw up the wheel and never get it true.

I'm sure genuises like grzmnky have some explanations out of their undergrad physics books about why I'm wrong, but from my experiences in wheel building, you're better off taking it slow and easy.

I completely agree with you. I was just trying to answer his question about some automated nipple driving gadget. Personally, I don't see the need for one. Heck, I don't even use a nipple driver. Unless you build a ton of wheels it is best to take it slow.
