Ok,
The barn door is coming along. I am playing around with construction methods and processes to get a feel before I make my final unit.
A question I have is, is the perpendicular alignment of the hinge in relation to the longitudinal axis of the arm critical? In my experimental version and with my limited woodworking skills I can get the hinge to within 1 deg of perpindicular to the longitudinal axis of both arms of a single arm design. I can get the threaded rod arm to the correct distance from the centre of the hinge without a problem, am I making myself clear here? I plan on using arms of about 19mm x 100mm.
My motor will be 12VDC, speed controlled with a PWM controller.
TIA
Steve
