Next use the "copy" command to duplicate the springs and line them on top of each other.

Now compress the top and bottom spring using Transform/Scale/Scale 1-D. Then join the 3 segments into one.

Next use the Pipe command by using Solid/Pipe. Use .2 units as a radius for this sample on both ends.
