Chandra,
You may want to see if your library has this book, "The Bicycle Wheel", 3rd edition, author is Jobst Brandt, and published by Avocet, Inc. My wife got me this book for my birthday last winter and I've used it to build some new wheels, and re-build some others. I did refer to Sheldon's website also and found it to be really helpful. I used my bike as the truing stand, just turned it upside down, and I made a crude, but fairly effective gauge to dish the wheel. You can see it on my Feb. 15, 2009 post (
