Is this what you want? I use d Cris Fulmers bending tool to bend a flat impeller around the spiral from the vid above, and just rotated a few times. Oh I see you want the tube. Should bend the same way?
Just checked yes it works but you have to "explode" the spiral for Cris's tool to work

Have you looked at the link provided above? The draw metal plugin lets you draw it no time or does it not work as shown

I guess you are right lol I didn't play with any paramaters but I think it can do what he wants by changing the diamiters at each end

You create just the spiral and then you have to ungroup it for cris's tool to work. The part gets bent around the spiral

Sorry I did not make myself very clear or did not understand your post.
The link I was referring was the one I posted early in the thread. It is a youtube video showing how to draw the 3d involoute using the draw metal plugin and does not use the shape bender. The plugin gives you the specific path profile and you can use the FAK to draw the profile you want. Here is the link for it http://www.drawmetal.com/download -
Right, here's a better version of this,I am just using curviloft and arcs. I will get the proper representation of a volute curve and raw that loft properly, then it just needs to be intersected at the top, and a cylinder punched through.

This is what you can get using the draw metal plugin. The plugin also has a taper maker but have not tried that yet.
Need for you to define the dimensions as well as the desired extruded cross section profiles -

right.. curviloft is the correct tool to use.. but do it like this instead..
[edit].. well.. what p just said before me.. lol..
sorry.. i'll leave this up for the visuals.. -
Here's a five minute version done with Curve Maker and Taper Maker and all else standard tools. I think that's the sort of general shape you want.

Update, 6 dia, no eye, taper round .5 to .25". 1 turn h=3"
Waiting on dimensions and taper cross section ( selection limited to round, rect, diamond,>..... -
If the taper is geometric along the length, I found using Curviloft "create loft junctions along a given path" worked in one process.
I used BZ Toolbar curves uniform B- spline (though other ways should work), Chris Fullmer Perpendicular Face tools to put a circle on each end, and curviloft- using just a beginning and ending circle. Just an idea if it works for you.

Gilles, this approach seems like the most promising. The loft path seems like a single curve, how was it achieved? Is it a bezier curve?
Thanks,
Jacques

2 tangent arcs-circle ?

J'avoue ne pas comprendre.

@ Gilles : Non même pas, j'avais même pas vu qu'il y a avait un fichier à charger!
car d'habitude les fichiers à charger sont en fin de post!
mais je me doutais que le "bleu des mers du sud" avait encore dû frapper!Et merci pour les V6! Ah si tout le monde en faisait autant!

C'était pourtant évident!

Pourquoi faire compliqué quand on peut faire simple...
