4 Iron ingots maayyy be a bit generic of a recipe for mods to use!

4 iron ingots in a L-shaped pattern to create an iron item L-shaped seems normal unless it has circuits and stuff then you add more items to the mix

We are going to require the launcher to use power. This means we need batteries, which means we will put a battery in the recipe avoiding conflict. Stay tuned

Yay batteries \o/
