The Auto Compressed Hammer will automatically hammer Compressed Blocks in its inventory as long as its provided with some energy.
It can be powered using any Forge Energy compatible mod.
If a mod adding steel is loaded, the recipe will require steel ingots instead of iron blocks.
To speed up an Auto Compressed Hammer, you can insert additional Compressed Diamond Hammers into the two upgrade slots available. These hammers can also be enchanted with either Unbreaking, Fortune or Efficiency.
