propeller balancer

Prop balancer for props from 5-10mm inner diameter
You need 2 1cm disc magnets
5mm threaded rod ca. 63mm long with two tops. I used a grinding machine and a drill (see picture) the thread on the clamp is made with the threaded rod
For balancing I use spray-paint

(I cannot guarantee that it is 100% accurate) but I'm happy with it
