Screw threads on a cone

[lithium630]

I need to add threads to a tapered screw (so it's cone shaped). I've tried following instructions on different threads here but I haven't been able to figure it out. What's the best newbie guide to accomplish this?

Determine the final dimensions of the threaded cone and multiply them by 100. Create a spiral path for the thread to follow. Create a shape to represent the cross-section of the thread at the end of the spiral. Use plugin FollowMe and Keep http://forums.sketchucation.com/viewtopic.php?t=16465 to extrude the thread. Create the cone to fit the thread. Select all and scale down to final dimensions.
