I'm very up for this - I've been thinking about building my own wheels for a while, but have been worried about ending up in a bloody mess surrounded by bent spokes after their first ride. This will be really helpful, thanks to everyone who's offered to help out.

To show my ignorance, what will I need to bring?
- Hubs, and rims obviously
- Spokes (any particular kind, size?)
- Nipples (any particular kind, size?)
