I have built a Morse code straight key using brass plates, small bearings, brass shaft, and some brass screws from power supply binding posts. The key is mounted on the same aluminum plate with my home-brewed electronic keyer with paddles and desk microphone. With this customized straight key, I hope to get a better sense of rythm in sending Morse code.
