Wow, that actuator is so smooth and quiet, and I think you did a great job on the design of that scissors lift mechanism. In my opinion, it's a nicer way to go than the screw drives. The lifting speed is more constant throughout the range of travel. Screw drives all seem to suffer from the jack rabbit start, and then putter out at the end of the stroke, but this takes care of that problem!
