    I'm working on a new design for this lift... Instead of the pushers being on the slider rods, I'm working on creating a cart that the pushers roll on. I think it will work with less friction and run smoother... pics soon, I hope.

    Coole lift ik heb hem gebouwd en hij werkt perfect! Ik ga hem gebruiken in mijn volgende knex ball machine.

    no you can use every knex motor that's powerfull enough. otherwise you need to gear it down.
