I create this thread in the event that someone may be able to lend a hand. I am attempting to model a drill in the shape of a cone, with a five turn spiral inset thread. My problem is in the creation of the thread. Using Blender I've been attempting to use curves to form the proper spiral, but to no avail, as for some reason unbeknownst to me, it inevitably twists on an axis I cannot control. I ask in case anyone here has had any luck creating a spiral that is viable for creating a drill thread.
Good question - this might help here Anyway, a combination of Screw and then Simple Deform (Taper) would seem to be the way to go.

Nice one Stannum, much better. I haven't (until just now!) used either the Modifier or Edit Mode Tool method, but for the OP's purpose you are right, the Tool is better. It's great to learn this stuff. The link you give is to the 2.4 documentation, this is to the 2.6 doc and explains it a bit more fully, I think.
