Just posing instructions on my heavy cannon, it uses a lot of pieces sadly but gets ok range with the heavy round and amazing range with finned rounds. So get building!

    okay, until i get my 13 pounds of knex, I'll try make as much as i can and i have about 2 thirds of the barrel done and one wheel. i cant wait for more knex!

    I like how that barrel design is strong, but it makes it difficult to pull back the rubber bands. also, there is no picture that shows the entire cannon.
