Page III.6: Counterweight arm
The roof is not very heavy, but still needs a counterweight or a spring to be operated easily.
One part of it will be a steel beam, it's heavy and also will be the anchor to the motor that in future will open and close the roof.
Here are two holes that I have drilled and threaded, in M8 dimension.
It was not that easy because the steel beam's thickness is 6 mm.
The steel beam will be mounted here on downside of the arm that lift the roof.
This wooden arm is weak and maybe have to be replaced with a steel arm in future.
It was easier to work with wood now in the beginning when I test ideas.
