I am building a big walker thing. It has a mining laser at the bottom that can be lifted on one half, and the other is attached to the vehicle.

However, I can't seem to find a way, because the hooks attached to the strings come off to easily. The studs are also facing down and I am not using Mindstorms.

I'm looking for a purely LEGO solution.

1 Answer 1



Key components would be Technic, Gear Rack 1 x 4 and Technic, Gear Worm Screw

Application of said parts are left as an exercise for the reader, though since OP says they're not using Technic, this might be a moot answer.

  • i'm going to change my question to include just lego parts

  • Well the key components are in this Worm Gear Pack. I'm sure the individual pieces can be had cheaper than the one set of these for sale on BrickLink.
