Firstly what your going to want to do is going to get the following items.

- Dispenser
- Pickaxe
- Another item you can switch to while breaking
- The item you want to duplicate

Once you have all of those follow the steps.

- Start by placing the dispenser and putting the item in the dispenser
- Jump on top of the dispenser and start breaking
- A couple hits before the dispenser is about to break switch to another item and break it with that
- When the dispenser breaks and reappears again, quickly press LT to open it
- Get the item and keep pressing A to place it
- Hold it down continuously
- When the dispenser breaks completely you should have one piece of the item you put in the dispenser
- Now go to a chest and put that piece in it
- Close the chest and then go to where the dispenser was
- There should be a piece of your item on the floor
- Pick it up then go to a chest and start duplicating!
