The connections in question are those where space is small. Typically, a phosphor bronze switch wire is joined to the cotton covered organ cable wire. The two wires are overlapped about 1/4 inch and soldered in that position. Both wires are usually supported by nearby guides.   The moment of truth is finally here as I now prepare to put modern telco wires on the entire organ. All the magnets are finished. Now I have to deal with these contact wire solder joints. There is no room to twist the wires. The original solder joints are easily broken, which I am not doing if I can help it. It is my scheme to leave about one inch of the cable wire attached to the phosphor bronze, strip away the old cotton = insulation, and solder to that wire.   As an example of the space problems, on the bench now is the sforzando switch from the Duo Art Player unit. Some fifty wires must be soldered to the phosphor bronze contact wires. The switch is about 7 inches wide, so doing the math, 0.14 inches is allotted to each side-by-side switch wire. How is this going to be done? There are existing guides in place for the new wires, but no posts.   After this switch is finished, there are several hundred more connection = on the player that must be done in like fashion. After that, all key = contacts in the console.   Bob Taylor

The heat conducts along the wire too quickly that close together. Just my thought.   F. Richard Burt ..

It uses a hand piece that applies heat to a very small local location. It's kind of expensive though.
