Hand crafted bow and arrow made of bamboo that looks perfectly natural. Can be fine tuned to be used as a real hunting bow hitting targets up to 50ft away (depending on the arrow used).
And it looks awesomely cool!
Step 1: Tools and Materials
What will be required to make this bow:
1. Hand saw
2. Hex saw
5. Hammer and Chisel
6. Machete/ Knife
1. Dried Bamboo (Thick and Thin) - You can make do with whatever type you have
3. Inner tube of a motorbike tire / Nylon string
Step 2: Main Parts
These require quite some hand crafting work and sweat!
How nice the overall outlook depends on your own skills and visual estimation...
[For midsection main frame]
1. Pick a smaller bamboo (a little smaller than your palms can grasp) and cut out both sides with a hand saw and chisel. Like in the picture =).
2. (Optional) Trim out another half of it to make it look like a gradient from full bamboo to quarter of the bamboo
3. (Optional) Cut out a dovetail ? its that what its called for the arrow to pass through in the middle
[For upper and lower LIMBS which bends and gives the elastic power]
1. Pick a full rounded bamboo with a diameter of 3 - 4 inches and split out 2 strips of about 0.5 - 8 inch thick. The length also depends on how long you want your bow to be.
2. Shave it out using a penknife so it becomes about 0.1-.0.2 inches thick. Depending on the hardness of your bamboo. You will know when you are able to bend bamboo a little.
3. Cut out lines/ channels for your string / rope , in my case inner rubber tube using a hex saw / penknife
[For front on midsection]
1. Cut out another piece of the full rounded bamboo slightly shorter than the main frame, this will act as a pivot to make the other frames bend more. Refer to picture
**The measurement really depends on what kind bow u want to make. If you need a really powerful force, then have it thicker, but keep in mind the thicker, the harder to bend, and your string has to be really strong too.
This bow was made for a short distance light shot ( to shoot a balloon ) for an event opening ceremony, not to hunt ducks.
Step 3: Put Them Together
1.Tie the main frame and frame cover together with jute
2.Then tie the limbs, first tie them to the ends of the main frame so they bend something like this /-\
3. Overlap the limbs a little over the frame cover and tie them up, you can use the rubber tubing (cut out in a thin strip for this). This gives even more flexibility to the bow and more elastic power besides only the bending of the bamboo.
Step 4: String It
In this example i am using the inner rubber tube of a motorcycle. You can get this from most bike shops. They throw it away and its free! You just need to get your hands dirty and cut em up.
Nylon string would be a much better choice since they don't expand as much, fishing ropes will do too... whatever depending on your needs =)
I used a sheetband knot (boy scouts should know!) at the end so it would no come off so easily
And i did not tie the strings to the bow, so it means i can remove the string and change it whenever i want, depending on the situation, and it also helps relieve the stress on the bow n string =)
Step 5: The Arrows
1.Split of some of the thicker bamboos and shave it down till it looks like an arrow. The straighter the better.
2. Use the hex saw to carve a groove on the back on the arrow
However bamboo arrows don't fly that well unless u add some stuff to it. for example a heavier pointed head and aerodynamic "functional feathers" My arrows don't fly straight... its because they don't spin when they are launched. The spinning motion is what allows it to fly in a straight trajectory. The same applies to rockets and bullets, they spin!
Step 6: Done!
Now go out shooting, be warned, these can be dangerous toys.
I have actually made a mini bamboo catapult and a 10ft tall trebuchet too!
All out of bamboo =) they are fun
