TopShelf - I've never used the Sullivan splitter, but it looks to me like it would allow the elevators to pivot individually so I don't intend to try them.

But soldering is easy. Go to your local hardware store and get some paste flux, rosin-core solder and a spool of fine brass or copper wire.

Before you attempt to solder, clean the metal with steel wool. Assemble the pieces and wrap them with the wire. I usually tin one end of the fine wire and solder it to one of the pieces so it doesn't keep coming loose.

Be sure to tin the tip and wipe it frequently on a wet sponge. The tin should be shiny solder covered or it won't work well.

When you're ready to solder, use the iron to heat up the work and apply some flux. Put the solder to the work, not the soldering iron. The whole process should take only a few seconds once the work is heated and the solder will flow out beautifully. Let it cool naturally and clean it up with soap and water to prevent corrosion.
