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?

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.
h rev p dia
1 0 0 0 0.625
2 0.081 1 0.162 0.625
3 0.162 1.5 0.162 0.625
4 5.38 29 0.217 0.625
5 5.5 30 0.022 0.625
6 0.625
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.
Thanks, but I'm okay with the manual method.
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.
