For more than a few, get a real coil winding machine involved.

For only a few, a motor driven electric eraser works fairly well.  Find 
something round to use in place of a rubber eraser and build it up with 
tape until the bobbin is a press fit.  It takes a knack but it's not too 
hard to catch on to.
