How to do this spring

max_mistarz

hello everyone. Is there any way to make this spring? It need to be tapered at the both end. I cant find any solution in the web.  I can do the spring but i dont know how to tappered it at the ends? and how to stretch it in assembly studio?

@Evan_Reese maybe you can help

@Axel_Kollmenter is right, @Evan_Reese could totally do this. But perhaps not at 6:30 in the morning? 

@max_mistarz, here is one approach you could start with. Keep in mind a split part or face feature usually works fine, but in this case it did not; so I used Thicken and Boolean subtract as a work around.
Link to example document

• Sketch the main shape.
• Revolve the main shape as a surface.
• Split the main surface with a helical surface.
• Create a profile sketch normal to the end of the new curve along the face of the main shape.
• Sweep the profile along the curve.

@MichaelPascoe
this is exactly what I would have done.

Haha sorry. I´m from Germany, here it was 10am ^^

Your solution is great! But how did you do the squeeze in the helix? I checked the document you linked to your comment but I dont understand how.

EDIT: ok I think I got it but its a bit too complicated for me right now. I couldn´t have this done alone yet.
