Has the hub been built up before with a different set of spokes/pattern?
Are the spokes seated ok in the hub?
Flanges straight?
Equal tension throughout the wheel?
Is it the same spoke thats breaking?
If anymore snap, rebuild the wheel with new spokes and using brass washers. The head will sit better into the brass washer putting less strain between the spoke and the hub.
