New Wheel Build

Hey all.
Now that the weather is starting to get colder (=less time spent riding), I'm starting to get a hankering to build up my first wheel. Right now, I only plan to build a rear wheel to use as a spare for the trainer... if I ever have a need for a spare front wheel, I look at building that up then. Anyway, while I'm planning on using it for the trainer, this wheel could conceivably be used out on the road in the future, so I want to make it out of pretty good parts.

I picked up The Art of Wheelbuilding, did a bit of reading, and I'm getting ready to start ordering parts. So, here are my thoughts. After reading the positive input about the Open Pro/Ultegra combo, the wheel will use an Open Pro rim with a 6600 rear hub (52 bucks at Nashbar right now... seems like a good deal). From the reading I've been doing, 32 spoke, 3x pattern seems like a solid choice (I weigh 165 lbs), but not too complicated for a beginner. Right now I'm planning on using 14/15/14 DT Competition spokes.

Here's my question. Spocalc lists the 6500 rear hub in the database, but not the 6600. As far as you guys know, are the dimensions on the 6600 identical to the 6500? This would be helpful to know when I'm looking at ordering spokes....

Other than that, any words of wisdom for my wheel building experience?

Thanks!
Nick

Yeah, I've often substituted numbers from one Shimano hub for another when calculating spokes.

My other piece of advice is to go slow when you're drawing the spokes up to tension. I find that if I only tighten them no more than 1 full turn at a time during the early stages and 1/2 turn after they start to tension, any extra time that it takes is more than made up by requiring less final trueing.

Good choice of components.

Rear wheels are more complicated (= difficult) to build because of the dish factor.

Sheldon's wheelbuilding instructions are gold. (http://sheldonbrown.com/wheelbuild.html)

Don't be in a hurry. Take your time and do it right. (My first wheelbuild took days).

Order a couple extra nipples. If you drop one and it bounces into some obscure corner of the garage you won't have to spend an hour trying to find it. (Been there, done that).

I recommend spoke prep., although it is pricey.

I recommend a tension-meter, because even tension, and proper tension are the two most significant keys to a well-built, durable, long-lasting wheel.

Nick, I am also considering building my own wheels. You mentioned Spocalc, is that a website or what? I am assuming it is and that how you determined the length of the spoke to buy?

Spocalc is an Excel spreadsheet that can do spoke length calculations for you.... you can find it here

http://sheldonbrown.com/rinard/spocalc.htm

Speaking of spocalc.... Spocalc tells me that I need 295mm for the left side of the rear wheel, and 294 for the right... I also ran the data from the spocalc database in the DT Swiss calculator and was given the same numbers. Just to be certain, do these numbers sound right to you guys? I would hate to spend $20-30+shipping on spokes just to have them be the wrong length...

Thanks for the advice guys, you're always helpful!

Yes they sound right. try building a front wheel first. Rear is more difficult. Can be done but if you have a chocie go for front. Enjoy.
