I toyed with sewing thread. I tied it to the end of the dart and fed it
through the cannon.
Here are my observations.
1. Rewinding and reloading works fairly well. As long as the dart doesn't
approach the cannon at a right angle to the barrel, it will usually load
fine.
2. The thread has to be fairly strong in order to overcome the spring
tension during loading.
3. Paying out thread without severely slowing down the dart is the hard
part. My attempts failed. You need some kind of spindle to rewind the
thread, but I believe you would have to remove it in order to let the
thread pay out unfettered.

| (...) Gear up a old 9V motor to spin the spindle very fast, and then spin it just before and while the dart is flying. You may be able to keep up the thread payout with enough gearing. Andy -- See my Visual Interface for leJOS at (URL) (24 years ago, 26-Apr-01, to lugnet.robotics)
