Rocket Experiment: Testing Thrust Using Angular Momentum Method

[FoxCommander]

Ok so What i am thinking of doing is testing the thrust of my rocket, I am thinking of doing it this way. I will have the rocket at one end of a rotating Planck and at the other end some counter balance. I will then fire the rocket of will its in the rest position, then when it is done accelerating i will then time the period of occilation.
Now i don't know if this will be enough information to generate an answer but I am hopin someone will help me, probably using agular momentum stuff, to determine the thrust.

If this is not can someone else show me a way i can do it without having to buy any equipment other than wood or something cheap

What equations will you use to design your experiment?

Thats the part that I am stuck on, I would think that the final velocity of the object would be the same as if the rocket was to be shot off in a straight line but i know that there has to be something about angular momentum and velocities there. Do you have any idea on where to start once i have the time period, and time of thrust and all the other information given? such as length of radius and the masses?
