Introduction: Connected Arm Lift, Sandroknexmaster's Knex Lift.
Hi this is my knex Connected arm lift ball machine lift which is used by Sandroknexmaster. I made this ball machine part because my previous knex Cleopatra ball machine broke in the process of fixing. This ball machine took approximately 2 hours to make without the parts for the project being found. So far it is my biggest and best knex model apart from my knex roller coaster.https://www.instructables.com/id/Knex-roller-coaster-/
This ball machine element has 4 working arms for the knex balls to be transported up or down the lift. It is powered by a single knex motor and 2 gears at the bottom of the ball machine. The process of getting the knex balls from the lower arm to the top one can be made in roughly 15-20 seconds making it a fast machine, as well as being very strong. It also has a mechanism which makes a knex ball go onto the first knex arm when ready. This action can be performed only when the arm is parallel to where the knex ball is. This can be seen on the sixth and seventh picture with closer detail. the wheel is there to prevent the weight of the ball and the holding area form being in the low position.
It is 152 cm / 60 inches / 5 feet long and 87 cm / 34 inches tall.
