Minecraft Secondary ID Block Converter (1.2 Working)

Description YT

Hey guys, Connor here. Today I have a video of a new redstone contraption. This contraption was founded (as far as we know) by my friend this_fat_kid. It changes the ID of a block that has a secondary block, duh. So go watch the video and if you enjoyed it and it helped, drop a like. It makes me feel warm and cuddily and it would make you feel like a supahstar.
