How to Create a Coil Spring with Blender 

Thank you, enjoy :D

You're welcome! :)

Is there a specific upper and lower control arms, you are aiming for?

Glad to hear that :)

No problem!

Yes Neil, you can, Just go to edit mode by clicking tab and then click "S" for Scaling and move the mouse to scale to your desired thickness.

Cheddar's, you may have to use different axis in the screw modifier. X , Y or Z

​@Electro3DTech Im having the same issue, and changing the axis' either just flips it(y) or makes it a cylinder(z)

@@dragoniccrab you moved the circle in Object mode, not Edit mode - you need to move the circle in Edit mode away from the Origin

@@appidydafoo Thank you, friend. I I did eventually figure it out, but I do appreciate the advice. I proly would've forgotten, lol

Make sure you are in "Edit Mode" and Press "A" to select all and then Press "S" to scale the small circle. That's it :)

@@3DElectroTech Cool, thanks... Btw how to put specific number instead of dragging? And also, last question, how to change scale unit in object properties to mm or cm instead of the default decimal 1.0? Thanks in advance... :)

@@cocopandan 1- To put specific number "Just type the number after pressing 'S' to scale". 2- To change Units "In the Right Lower section, you will see an icon named 'Scene Properties', inside it you will find 'Units', Change 'Length' from 'Meters' to cm or mm". I hope this helps!

@@3DElectroTech Excellent! Thank you... It really helps me...

@@cocopandan Glad to hear that :D

BONSE, That will depend on the animation you are looking for. There are different ways to animate things.

@@3DElectroTech to press it down and leave it to turn up again
