Intro: Knex Mechanism
I started a pump knex crossbow but I do not have the pieces to finish so I thought I would show someone who has the pieces my idea.
How it works
The pump is pulled and through a series of pulleys it brings the rubber band back. Once pump is completely pulled back it laches onto trigger and once the trigger is pulled it fires a bullet. I also had trouble with a mag so ill let someone build it and find a way to make a mag for it
Sorry I can't draw worth 2 cent
If you do build please give me credit for the design
