Today I visited the local representative of
www.intorq.de company, they sell reduction gearboxes, brakes, etc. Im doing the homework for a turret like yours SANS the compressed air, after speaking a while with an engineer about doing it with gearboxes I asked: what if I use a brake?
He replied, its less expensive solution for sure, and suggested to take a look at these brakes:

I wonder if one of these can be used to hold the turret safe/firmly in place. What do you think?
