Grounding pickups and toggle switches that use braided guitar wire can be tricky - the below video offers an easy technique to use yourself. The key is tinning.
Tinning is winning. This means maintaining a well tinned soldering iron which allows for easy heat transfer and easy flow of solder onto the braid as well as tinning the pot casing and the wire itself.
- Tin the back of the pot where you want to ground the braided wire. Spread a small puddle of solder onto the back of the pot casing.
- Tin the under side of the braided wire that will be grounded to the pot.
- Hold your soldering tip (ensuring it is well tinned) against the side of the braided to transfer heat.
- Start to flow in your solder - it will gradually creep up the braid.
- Hold the wire firmly in place with a screw driver or similar device and rotate your soldering iron to spread the solder over the braid.
- Repeat this process on the other side of the wire.
