Bamboo Crossbow

Lock in upright posistion




Simple wooden trigger



Lock upside down showing large  notch

This crossbow is a third generation of crossbows that I started mucking around with after seeing the Hoods Woods jungle crossbow. I never managed to get Rons trigger to work well so I moved on to the next design.

These had problems too but at least I manged to shoot off a few bolts. The trigger was simply a wooden rod that pushed up againts the bottom of the arrow where it notched the string. The string was held in place by the end of the groove.

What tended to happen is that the string would bind on 1 side more than the other. Also as the draw weight increased it became harder and harder to pull the trigger and the arrow tip tended to lift up.


Note the double  for extra power




So I made a goats foot style trigger from  some whale bone I had hanging around. The thought on this was that I could carry it around almost as a decoration and it would be a problem carring security on planes tho the parang I used to make the rest of it might be a problem.
This design was based around that I wanted it to be made with just a knife, a parang in this case. Plus a swiss army knife for a little of the finer work. it took about 2 hours to make not including the trigger or the bows as I had them on hand.
The binding hides the fact that all the parts are also notched and fitted to each to reduce the chance of false triggering due to a sloppy trigger.
Tho I must admit that the I used power tools to make the bone trigger. Saying that I am confident I could make a working trigger with just my  SAK.
The cordage is all natural made from seaweed bar the bowstring which is 3 mm rockclimbing cord.
So why all this effort?  It takes years of practice to get great at shooting wooden bows but about a day or 2 to shoot a crossbow to the same degree of acuracy.
