Definitely not! I have got a cheap solution planned, the motor/gearbox I'd use has a 463kg/cm max efficiency torque at 12v, and I'd then have that going to a 4:1 bevel gear setup, or it'd be geared up to some threaded rod and would become a sort of micro linear actuator. Apparently the whole system could be run at 24v which would provide a slightly worrying amount of torque, whether that would translate well to this application I don't know, nor if I'd be able to house it successfully, but I rather hope I could!
