Balancing turbine rotor assembly

Balancing turbine rotor assembly
This is my 20 year old balancer from a design in the GTBA there will be better ways of doing it now with software to analyze the signal.
I just use blu tack and move it around/increase /decrease until signal is reduced .trail and error method you can get quick at doing it .
it does have a led flash light to highlight heavy spot but not bright enough to see unless I turn the light out!
