Bridge grounding wire

It doesn't matter about the shape but I usually use a small piece of shielding tape to secure the ground wire to the bridge.....

 

I wouldn't recommend duct tape, the shielding tape is a lot thinner and it is also conductive.....

Here's a link for Conductive shielding tape...

The shape of the end of the wire is not too important, but of the shapes you mentioned are fine. What is important, however, is there must be a good electrical connection. On the underside of the bridge, rough up the metal with a little sandpaper where the wire will be making contact. That is to remove any wax or grease or oils or varnish. Now when you mount the bridge to the body it will make contact with the metal. It will also crush right down into the wood a little which will give it a solid contact.

And as tbub said above, don't use duct tape because it will have a residue that could impair a good connection.

 

It probably should be in the shape of a bass clef. No particular reason though, and it may be difficult to manage the two dots.

 

No need for the tape. I spread the wires out like a fan shape. If you get it too thick, the bridge will not set flat on the body.

 

Do it like this.

 

this method would be great too....

 

Why would there be any glue involved? A "huge blob of glue" would almost certainly prevent the bridge from laying flat on the body.

What you need to do is take a strip of copper tape, and lay it on the surface of the body, for the bridge to screw down over. In the recessed area where the ground wire comes through, solder the ground wire to the copper.

 

that would be solder that's securing the wire to the copper tape. I do the same thing.
