As long as I don't see any more cannons... also its Not Enough Items included with tekkit.

Here's some tips since everybody had the same mods

while using NEI. You can press R to see how you could make the item.
You can also search for the item by using the search bar at the bottom of the inventory screen. Make sure you hit enter before checking the recipe for an item.
Also I left you guys a recipe on the spawns back wall
