Adding a Wire weed guard

I am reliativly new to pouring. Question is, what would you all consider the correct way to add a wire weed guard to a factory mold without one. I am interested in putting it on a do it minnow underspin. And if someone is willing to load some pictures of some you have altered and shown in the mold would be greatly appreciated. I work good with pictures :)

Thanks

Use the search function, look for adding weed guard. DrNip has posted a bunch of pictures and explanation of how to do it.

Here are a couple I did. Kind of rough from a few years ago.

Sorry. I read the thread wrong! This is for a wire keeper.
