Hi, BOOMBOX51403 here again with a vanilla anvil thrower! It throws in an anvil (or any other physical block), making it go north and south in the air. The tekkit version is going to be sand or gravel, not anvils. The anvils are versions 1.4+ making them unavailible in tekkit. Do not copy. This has been a machine off of a machine off of a youtube tutorial. Click the spoiler below for an anvil thrower warning/note.

Warning and note
Do not put the anvils or other physical block on the front of the piston head. It will crush the redstone if you do what the warning tells you not to do. The schematic file is actually a world save. Learn world saves before downloading if you haven't yet.
