Cannon: Trigger/Lock/Sled Assembly finished, plus This week's winner!








Finished the trigger/lock/sled part today!

As you can see, the sled will glide between the two parallel 4x4 (10cm square) wooden beams, which are 33 cm apart. The trigger is a long upwards pole that you have to pull back to fire. I drilled a hole near the top of the trigger pole so I can later put a length of rope through it and pull from, like, 20 meters back (safety distance).

The winch will roll up strong mountaineer grade rope, actually two of them (you can see the massive rings I attached for the two ropes). It will take about 30 turns of the winch wheel to fully cock this monster.


The third picture shows the 4kg shot put ball, loaded in the double pouch. This is the largest diameter ball (10 cm) the weapon can fire, smaller balls are never a problem as long as you don't go smaller than 25mm (1").

The conventional slingshot is to give you a feeling for the size of the cannon...

Tomorrow, the "barrel" assembly!

Oh, by the way, this Sunday's winner is PetersonOD... congrats! Send me a PM on youtube with your slingshot choice (Panther or Cougar) and your address.

Next raffle is on, of course! Winner will be drawn next Sunday.

    Wow! You have really put some strength into the design. The 20ft. rope pull is a smart idea. I wouldn't want to be anywhere near that cannon if it should come apart under the tension. Safety glasses, at the very least, will be worn? :) Good craftsmanship from what I can see. If the rest looks like this, then it will be a tremendous success. Well done, Joerg.

    If Einstein is to be believed: For those of us who survive WW3 and have to fight WW4, we can tell our comrades,'Yes, back in the long ago days when we could see images floating in the air, Joerg Sprave, the venerable Weapons Master,blessed be his name, taught us how to make weapons with sticks and stones--and rubber!' ---- Mad Max would be so proud! :)
