Marblevator, Self Reversing Screw Lift.

myminifactory

I've created many "Marblevators" using various lift techniques to lift a marble from the end of the track back to the start of the track. In "Marblevator, Self Reversing Screw Lift", I've designed a "reversing screw mechanism" incorporating twin travelers. As the reversing screw rotates, the travelers raise and lower two slides and buckets. The buckets pick up a marble from the end the tracks, lift the marble to the start of the tracks, where the buckets dump the marble onto the start of the tracks. As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.
