Force required to rotate spindle.

[sehamm10]

I am working on a six sigma project to reduce endbreaks in Beaming (textile). I am trying to find a device to measure the force required to rotate a spindle. There are 1000 spindles that hold packages that are transferred to a beam. Each spindle has a wooden brake that applies a force to the spindle to reduce free wheeling with variations in speed. I want to set up all spindles the same. Does anyone know how to measure the torque required to rotate the spindle?

I guess I am looking for something that can apply a constant rotational force and look at how many revolutions in a certain time period. I am trying to get all the wooden brakes to apply the same force. Anybody know what device I can use?
