Deconstructor

From the Galacticraft mod, primarily used to deconstruct your old Rockets once you've made a better one. Can also be used to uncraft things. You will get back 70% to 75% of the original materials. This machine requires energy to work.

There is a limitation however, you can only deconstruct things that have a recipe which returns only 1 of that item. You cannot deconstruct Signs or Tin Canisters because their crafting recipes return 3 Signs and 2 Tin Canisters.
