This is the reel part for a ham radio antenna launcher.
These launchers use compressed air to launch a small weight high up in a tree to pull a wire antenna or similar high into the air.
The old method of making these was to use a bow fishing reel, but the company that used to make those stopped producing them. There are some specialty shops which make these, but they charge approx $200, so I decided to make my own, and this is my result.
The final picture should show the small holes on the radial sections. The intention of this is to stick 2 small pieces of 1.75mm filament into the hole, with the natural curve curving inwards. This way when the launcher is loaded and ready to fire, the string can be prevented from falling off by slipping it between the pieces of filaments, yet when launched, it can easily break free.
