Duplicate Elevator Shaft glitch for version 1.5.2 of The Blockheads game. Also works in ver 1.5.1. You need to join any multiplayer world (any type) for this version of the glitch to work. After you have duplicated all the Elevator Shafts you need, you can ask a server player to drop a Portal Chest for you (or craft it yourself), and put your duplicated shafts inside. Then go to any world on your device and craft a Portal Chest (if you don't already have one), and take your duplicated Elevator Shafts out.
If you mainly play single player, then whenever you want to do duplication, just put lots of Ladders and at least one Elevator Shaft in a Portal Chest, join any multiplayer game, ask someone to drop a Portal Chest (a loan which you can give back after you are done). Take your stuff out of your Portal Chest, do the duplication glitch, put all the Elevator Shafts back into the Portal Chest. Give back the Portal Chest (drop it). Log into your own world and you will see your duplicated Elevator Shafts on your single player world's Portal Chest.
