Introduction: Floor Double Arm Lift, a Knex Ball Machine Lift

About: Hey! I'm Sandroknexmaster. I like building with knex, especially ball machines. I live in Belgium. I speak Dutch, but also English and French. I hope you like my stuff, and like always comment, rate & …

Hello everyone!

The Floor Double Arm Lift is the first of 2 lifts first seen in my ball machine Revolution.

This one is a double arm lift. Nothing special you'd say. But...

It's a bit different than a standard arm lift because the balls enter directly from the floor, not from an entrance track (as the title says).

When it's not in a ball machine, I think the Floor Double Arm Lift looks quite ugly. But it looks better when you build a ball machine around it.

If you're going to build this lift, please read the image notes, they might come in handy!

You can always send me a question if necessary with a comment or PM.

I hope you like it and thanks for watching / building!
