Bus Connector

Not exactly a tool but this method of making a bus bar can come in handy if you need one quick and don't have any brass or copper bars laying around.

I used an old terminal strip for the parts. These come in various sizes and mine happened to be #12.

Two of the screw connectors and 4 screws were removed from the nylon block.
Tin one side of each and then solder together without soldering the screws of the little copper
piece that protects the wire from the screw.

Put your wires in and heat shrink for insulation. Much better than trying to solder 4 wires together!
