Need help makeing screw edge

yes. . .this is true. I just like saying lefty-looie.

What's happening here is very logical.
You are using a Ruby that keeps a section profile always "upright standing".
Imagine what the profile could do when the path is also vertical...
And look carefully Blah 11, you are not getting your threads right at any points of the spiral except at the bottom (as in the 3rd image).
The solution for the problem is, I assume, to make the reference path stand up and then re-apply the ruby.
Hope the images will explain it better.

Well spotted takesh

Hope the images will explain it better.i'm not really following this.. what do you mean by 'you are not getting your threads right at any points of the spiral except at the bottom' ?
is that in reference to the original post or the state of the thread when you made your post? as far as i can figure, the threads are correct at all points of the spiral (i'm talking about the .skp in the 8th post of the thread).. are you saying something is wrong with that that i'm not noticing? -
It's about "Follow me and keep" plugin, Jeff. As it works,it will always keep the profile straight along the Z axis so you have the correct results (in this case) if you follow a spiral wound up along the Z axis.

Oh this is a solved problem... sorry I didn't see the solution has been posted. Missed your model in post #8.
I saw the image in post #11 and thought it's an ongoing problem.
I was refering to blah11's quoted image in post #11.While I was looking at Jeff's model, an odd thought came down to me.
This whole thing can be done without using Ruby - I'll explain.
BTW you can do it as elements horizontally lying down (as in the image in post#11) with this method.

OK its not the best but I am proud of my accomplishment heres a preview of the screw edge
I knew it would be valuable for me to come to this forum. Now is there a plugin that can turn things inside out? I would much rather do that instead of making the other edge which is a pain.

Look what you got there Blah, it's already reversed!
I mean, it's a matter of which way you extend these thread surfaces as a volume, introverted or extroverted.
Or am I missing something?
Just group them and make a copy in the place.
Keep modeling one of them as an internal volume, and the other as an external volume. -
I wasn't thinking when I modeled it I hollowed the inside, I guess it doesn't matter I found a different way to do the 2nd part anyway thanks,
