I decided that the metal sinnet ring knot had to have more crossings, for stability's sake. This first attempt stopped with only one full pass through the entire knot, and I'm thinking that the next one should have two, to make it both more durable and more "filled in" looking.
Here you see one full pass, a (4,17) torus knot wrapped around the inner ring and just held in place with a bit of string. Scroll down for views of its progress.

The reversed-direction torus is well-started here, with almost two circuits around the perimeter conpleted. It's important to keep the intervals as even as possible, with wire, since any kinks are permanent and a mislocated turn is a disaster.

Here, all tied up but with the ends still showing. Those will be trimmed even and soldered together, to keep the knot from unravelling. If I do it again and double the knot, I will probably just tuck them inside as neatly as possible, since the two strands will support each other and prevent the knot from coming un-done.

Here it is with the core removed. The ends are still floating free.
 |
Ends are soldered, here. I tried, just a little, to do a bit of bending and moving of leads to smooth the flow of the knot, but it was very hard without the core to hold its shape. I think it will have to remain as it is.

This is a closeup of where I changed direction, the meeting of the clockwise and anticlockwise tori (toruses?), with a sliver of wood tucked through to help it show.
