I dont know if someone else has found a way before but Ive been looking for a way to do this. yesterday I saw someone who posted an update vid. immediatly when I saw some of the new blocks (one in particular) I finally thought " THIS COULD BE IT!" I didnt have time to do it yesterday but today I had a bit of time to test it... AND IT WORKED! I hardly belive it myself becouse all my last things ended in failure, but it really worked. I posted it up to the steam workshop as a blueprint to show everyone it. It requires no mods, just the block that are currently in the game. best part, NO ROPES! not that ropes are bad... but they are glitchy. In anycase hope you all enjoy.

ps sorry for bad spelling and grammer. I dont currently have time to spell check or grammer check. I may come back to do it but if I dont, then I hope I atleast got what I wanted to say across to you. plus I thought this is something that should be told to the comunity to advance our machine making skills in this game. more complex devices here we come! soon we may even be able to make an Iphone in this game lol. just kidding of course though. but yeah the gears idea worked so, start building people.
