Spring fabrication/calculations

[speed]

Does anyone know of a good and safe way to make large wire springs in a tool room other than using a lathe?? I'm talking wire over 1/4" or so.

There is a 'spring calculator" and "spring designer" that is web based at www.catalogsprings.com. For most of our needs, there is something close to be had. We use a haas cnc lathe to make some of our repair parts in house, problem is over a certain size, it's harder to find solutions!
Thanks.
