I started with a helix, sketched a circle on an end plane of the helix, and used those sketches to sweep the active coils.
Is there a "best way" to model closed & ground ends?
I'm sure there are a god amount of examples or topics on this within this forum from the past, so try a search to see what can be found. I tend to create one helix with the coil qty, pitch, and mean dia that I want. Then I create a helix at each end of the 1st helix which creates the end coil, the pitch slightly greater than the wire size used. Create a 3D sketch, convert the 3 helix into one sketch entity. Use this 3D sketch as a path for a sweep, add an extruded cut referenced to the end point of this 3D sketch path to create the ground portion of the springs.
Have you tried a "Variable" helix path, and then a couple of cut-extrudes?
I had not, but now I have.
Maybe the table interface is my problem but I can't seem to control the pitch changes well enough.
It become a dance of me inputting values it doesn't like, so it generates an error with bookends on the values it will allow. Using that feedback I can walk up to the values I want, but it seems like my active coils are increasing their pitch along the length of that section.

I don't know if it's the best way, but I use planes & Cut With Surface to create the ground ends.
Slice planes sounds sensible.
You can try this macro, if you don't want to model it yourself
Thanks, but I'm okay with the manual method.
