Building wheels

I've got a good amount of experience with wheels - I often take them apart and put the back together when I get bored, and once I had a bunch of rear wheel drive side spokes bent and had to rebuild the wheel. I was wondering - assuming one doesn't use a radial pattern, how do you determine spoke length? (Building from scratch, not rebuilding a wheel). I really don't have a particular project in mind (yet) but this has been bothering me since my grandpa got me into tinkering with wheels (don't know why I never asked him...)

I always use one of the on-line spoke calculators that has a data base of hubs and rims.

If either the hub or rim that you are using isn't in the data base, you have to measure them very carefully. Measuring hubs is fairly straight forward. To measure rims there's a process using 2 spokes with nipples, each cut off to exactly 200 mm, and a ruler in between.

Years ago, before I had access to on-line spoke calculators, I calculated spoke lengths for a wheel using a long paper and pencil formula. That was a trip. The spokes came out a little shorter than ideal but the wheel worked OK.
