3D ring/rope wooden puzzle solution?

I have a Eureka 3d Puzzle G / Model G / Gringo:

On the box there are 3 puzzles:

1. Remove the ring
2. Remove the rope
3. Move the ring to the other side

While Eureka does not appear to list this puzzle in their solutions page, another site shows a solution to the first puzzle. However I cannot find any for puzzles 2 or 3.

Is anyone familiar with this style of puzzle and can offer a solution to either of the 2nd and 3rd puzzles?
