So yeah (a little jab at Nate from Coast 2 Coast Pinball)
I picked up a cnc machine from this company (www.inventables.com) and some of the customers do not like to solder so they came up with this solution
this really would only work for two wires that you wanted to solder together, not a wire to a switch or coil.
It’s called a solder sleeve, and it joins wires together electrically and mechanically at the same time using these three common items cleverly combined:
Heat shrink tubing
Hot melt glue
It’s crazy easy and fast, and requires no soldering iron- just a source of heat such as one of our new heat guns- any heat gun should work, but a hair dryer may not get hot enough.
The heat melts the solder to form an electrical connection, melts the glue to hold the wires in place, and tightens the heat shrink to form a strain-relief and insulate the exposed wires. All at once. Boom.
Bonus: The resulting joint is waterproof!
Solder sleeves solve another related problem- splitting one wire into many, or vice-versa. It’s just as easy (and just as quick) to join a number of wires using the same technique. This is useful in situations like slaving two stepper motors to a single driver, or running multiple connections to the GND of an Arduino:
looks like a great thing to try out. my only work is that the coating that is on our pinball wires might be too thin and the heat gun would melt them.
here is a question from the comments on the blog
How do you avoid a cold solder joint? Won't the insulation start burning before the solder and wires are at the right temp?

These use hi-temp shrink and low-temp solder. Scorching the insulation shouldn't be a problem unless you leave the heat gun on the wire with no shrink over it too long.

looks great to me. i have no problem soldering, but i can see where this could be useful.
