Introduction: Project Lifts Knex Ball Machine

Picture of Project Lifts Knex Ball Machine
A knex ball machine with a normal chain lift and a modification of I am Canadian's lift. It also has Darth Trainman's red ball drop. Cranks are supposed to be used because they are quicker and have better precision and strength than motors.

Cool! If you did have more Knex, you could make it more eye pleasing and smoother. Good job tho!

A nice little contraption. You should vbe able to make some really well made big ones when you get more knex.

That motor is going way to fast its almost like a catapult

It's not the motor, it's because the weight of the arm. It just falls down, the motor doesn't control the arm for that part. The motor just lifts up the arm, the arm pulls itself down with its weight.

You should give it two arms, so the both can pick up the ball, and act as a counter-weight for the other one. It should cause a smoother rotation.

I would if I had the pieces left over. I don't have any more red, yellow, or grey rods left to use.

Looks pretty good. Could use a bit more support and strength, but I like it :-) 3*, good work.
