    Can a wheelbuilder please help me out

    Okjay well im trying to build my first wheelset. I didnt want to spend too much money on the highest quality parts becuase its my first so im doing 32 hole 3 cross. I am using DT swiss Hayes front hub with vuelta rear. DT Swiss competition spokes. I have taken apart 3 wheels and relaced them to get familiar with the process, but now this seems much harder. I used the DT swiss calculator and all of my parts (aside from rims) were in the database. Im having some hard time understanding it though. I see ri. and le. which i assume is right or left, but what i dont understnad is hjow do you determine which side is right and left? Or is it like for trailing spokes use a certain length and leading spokes use certain length. Please help. Oh and to get the best help i would guess i need the measurnment thing DT swiss gave me from the calculator.

    Right is ALWAYS your drive side, left is always your non drive side, just like on pedals and cranks. I haven't used that calculator but I would assume thats what they are referring to.

    Hi,

    The drive side ( *usually* the right hand side of the bicycle) is the right side of the wheel.

    Rear wheels only :
    Where you need to dish the wheel ( ie set the rim closer to the drive side hub flange ), the spokes on the left side (non drive) are longer by between 3 turns of the nipple and 6 turns. You can use different length spokes with the longer ones on the left. Or, if your spokes fit well near their mid range, you can get all the adjustment using all spokes of the same length, by tightening the drive side by 3 or so turns before reaching final tension all over.

    Note: the most common mistake made by beginner wheel builders, is to not set the pattern correctly around the valve hole. Its easiest to get it right by fitting up the spoke adjacent to the valve hole first, then after the first round (of 8 spokes in the case of a 32 wheel) rotating the hub so the first spoke goes away from the valve, before crossing and fitting the next 8 (on the same side).
    Then turn the wheel over and fit the other adjacent spoke, its 7 mates, then the final 8.

    That way the valve will have the most access space.

    Good luck !

    Lets go back to the spoke length calculation because if this isn't right the whole thing isn't going to work. How did you determine your ERD (effective rim diameter)? Most of the spoke length differences stem from the rim being used and measuring a rim with the necessary precision isn't as easy as it sounds.

    You might want to look at this thread, posted on 10/18:

    "Need help with spoke length"

    There is a discussion of ERD in there.

    well what i have done is put all of hte spokes that are going one way in first, that way its much much easier to install the spokes going the other way becuase they go from the inside of hte flange out

    When I started building my own wheels, I used that book and Barnett's as my major references. There is a lot I like in Schraner's book, but be aware he is very opinionated (like me). For example, he is a strong proponent of tying and wiring, which some "experts" such as Jobst Brandt say is hooey. I started out with cheap rims and hubs, but have always used good quality spokes. I use the DT Competition 2.0/1.8 double butted spokes for everything now and this was influenced quite a bit by Schraner. I would love to own Brandt's book, but it is ridiculously expensive. You can get Barnett's brand new for less. I'd suggest you look at Sheldon Brown's site and another one I just found that is very interesting is: http://www.peterwhitecycles.com/

    I found Barnett's the easiest and most idiot proof for lacing the spokes. I also think it gives a more complete explanation and process for truing and tensioning.

    Schraner shows a resonable method for lacing. I think his cause/effect explanations for what happens during truing, dishing, and tensioning are excellent. Yes, this book was well worth the price. I like his "strive for perfection" mentality. He says it's "art", Barnett's says it's "all science". Personally, I think it's a combination of both.

    FWIW, even my first home builds are still running quite nicely - and that pretty much says it ain't rocket science Take your time, have fun, and enjoy your new ride!

    Okay well now i have a new problem. Thres a few spokes loose out of their pile corresponding with their size. How do you actually measure the length of the spoke. When a manufactur says 261mm what is it 261mm from?

    It's measured from inside the elbow to the end of the threads. If you have a metal scale just hang the head of the spoke over the end and read the length at the end of the threaded end. That's it.

    Length is measured from the inside radius of the elbow but don't worry about measureing them. Stand the threaded end of one of the loose spokes on a table and trial fit spokes from the same-size piles next to it until one of them matches.
