There is a whole chapter of how to make stocks and triggers. You can use the lockbow design like in my thread about a new crossbow.

   Matt C,
   Indeed, do some google searches, as there is a lot of good stuff on the web now. For some really pretty pictures (drool!) to look at, try these links:

   http://crossbows.biz/

   http://www.crossbows.net/

   or go to google and type in New World Arbalest and hit search.

I made a crossbow recently(my second crossbow). The prod is made of multiple bamboo pieces tied together like a leaf spring. The prod is weak because I have no big bamboos. Just for experiments and fun. It's a chinese style crossbow. The crossbow can't shoot far and can't make a real weapon. Tongue

I eventually figured out an extremely simple solution for the trigger. Just nail a small section of 0.5mm x 7cm rectangular cut wood or bamboo near the slot for the string. The rectangular piece of wood should be able to rotate 360 degrees freely. This will push the string off the slot when pressed with the thumb from above. Very simple!

I'll draw a picture to show it later, as I don't have a camera right now. It works for me.

.5mm

Sounds cool, I'm looking forward to seeing it.

I placed the quarrel 2 inches away from the cocked string. Mine shoots best at this position.

Hey, Loh-kah-hoe!
ThanX!! That is a very interesting link! Pretty pictures, too! Cheesy

As for your own crossbow, you seem to have come up with the simplest possible design for a "notchlock" This type of lock mechanism is called a notchlock because the string fits into a notch to hold it in the full draw position. All of the others that I have seen have the release lever ( or trigger, if you prefer ) in the center of the stock, but this requires cutting a space into the stock to take the lever. I have never seen one before where the lever is simply pivoted on the SIDE of the stock.
I would think that this might not work well because the string is released asymmetrically, but you say that it actually works quite well? I can see the advantage to this arrangement as it would be very easy to make.
Could you post some pictures for us?

I'm waiting for my sister's digital camera, don't know if she will lend me. Roll Eyes

But, the quarrel is placed 2 inches away from the notch, it will be hit by the string, so I think there will be no problem as there is time for the string to become straight.... ???

However accuracy does improve after slightly twisting the vanes for spinning. No pin-point accuracy, .... The quarrel flies quite straight at ten metres. Maybe now it leaves to the practice. ???

Back to the trigger, before, I made a similar trigger, but on both sides. That one I made long ago is very crude and not perfect. But, anyway this is better than levering with my own thumb. Roll Eyes

Someone should try this out to see if this really works for everyone.
