Is this sort of thing what you are looking for done mainly with technique in this TUTORIAL and then some manipulation of path and nodes. Somebody who is more artistic than me could do a better job.

I was just messing about learning the text functions and came up with this.

Update Been doing some investigation into internal teeth profiles out of curiousity much to my suprise it seems its as I had done it, the reverse to an external gear! 7.2 Tooth Parts of Internal Gear Because the internal gear is reversed relative to the external gear, the tooth parts are also revers...

But, from a technical point of view, I don't think it would turn too smooth.... I think your right. The profile I think is entirely wrong for the ring, I took a normal gear generated by the render gear function in inkskape and differenced it with a circle. To lazy to find out or even to generate th...

This is the completed version.

how do you calculate the centres of the sun gears ? Basically I didn't it was more by trial and error. I found examples on the internet and found 12 teeth sun,12 planets & 36 outer ring. I then used the "render gear" in inkscape to create a 2D drawing and found they fitted perfectly. ...

The shading took ages to sort the technique out but once I got into the routine I could get along pretty quickly and I think if I did it again I could do it in a few hours? I have been thinking today there is a simpler solution I could have used which would have been quicker overall but slower at th...

HI Been working on and off on this epicyclic gear train for the past four weeks. Just about to start rendering the carrier but looking at it overall something does not look quite right not being very artistic myself I wonder if someone can tell me what is wrong? Fairly new to Inkscape and learned a ...

How can I find, if I have any uclosed (open) paths? Another way maybe is to use the XML editor, all the closed paths the "d" positions end in a "z" as in example below. 1st open 2nd, closed, also first and last pair of dimentions are the same. It may be easier to open up the fil...

Just been messing about with various affects in Inkscape and came up with this. http://i148.photobucket.com/albums/s26/DaveG27m/web%20cam%20train/spring1a.png Click image to view larger image Found when using cloned tiles it is better to put each clone tile on different layers as it is easier to kee...

I think the problem is you have rotated the ellipse towards you but not the earth as the poles are at the top and bottom.Both need to be rotated together.

This my first Inkscape drawing without using a tutorial.
I learned a lot more about Inkscape doing this.
As you can see I am more of an engineer than an artist!
