Ham Radio Morse Code Straight Key

A simple Morse code straight key.
Needs the following hardware:

- 2x M3x10mm hex screw
- 2x M3x16mm hex screw
- M3 nut and washer
- wire and M3 wire crimp ring connector
- 3.5mm stereo jack
- 2x 5mm diameter 2mm thick neodymium magnets

NOTES:
- The paddle opening will not be a perfect circle. To correct this I use an 8mm drill.
- On the paddle bearing surfaces I use a small amount of light silicon grease.
