    As can be seen above, the red arrow head line means the force of string F1 and hand operate force F2, L2 is about 10 times of L1. That means if the bow is 200 pound when full cocked,the operate force may one tenth of bow (20 pound). This result is very intersting since the proportion of cock lever is changed during operating.

    Very good posting . Very clear. Would you have any idea as to how many man hours it takes to make it?In real action ,you can see how very deadly it could be.Thanks for your effort in this.

    Love the magnet idea! I use two little brushes at the muzzle but this is much better.

    Very nice work, I also love the idea of magnets to keep the bolt plated and the end of bolts in cross shape curved. 

    I maked a Chu Ko Nu dragon 5 years ago but on a smaller scale 1/4. Mine was ebony and boxwood carved with a multi-bamboo bow.
    It always works perfectly.
