All of a sudden i realised that I had no way to couple the stepper motor to the threaded rod. After speaking to Chucky (Santosh) at work he told me about a way to not only couple the drive shaft to the rod, using a piece of pipe and some hose clamps. He informed me of the additional benefit of not requiring the threaded rod to be exactly center due to the flex in the pipe, this also stops the motor bearings from wearing out.
