The video showcases the creation and testing of a take-down bow made from PVC pipes. The bow's core is composed of discarded PVC pipe pieces with a 2mm wall thickness, reinforced with cable trunking with a 1mm wall thickness. The bow has three parts: string, limbs, and handle. The limbs are original and reinforced with an insertion, while the handle has a special form that enables the arrow rest to be in the motion plane of the bow-string, preventing the handle from diverting the arrow.
The creator demonstrates how to make the bow, including:
* Reinforcing the limbs with cable trunking
* Shaping the handle using a profiled rigid handle
* Creating the arrow rest using a piece of pipe and toothbrushes
* Making a quality string using a reeling frame and serving techniques
The bow is designed to be extremely light and compact, fitting inside a quiver. The creator plans to make an ultra-light and powerful compound bow using Kevlar and carbon fabric in the future.
The video also covers safety warnings, such as the potential for breaking the PVC bow and overheating the PVC. The creator encourages viewers to provide feedback, promising to edit and dub a more detailed version of the video if it receives a good response.
Here are the key facts extracted from the text:
1. The bow is made from PVC pipes with a wall thickness of 2 mm.
2. The bow has three parts: string, limbs, and handle.
3. The limbs are reinforced with an insertion made from cable trunking.
4. The handle has a special form to prevent diverting the arrow.
5. The bow can be disassembled and reassembled quickly.
6. The bow's core part is made from PVC pipe pieces that were thrown away.
7. The author used a 26” (66 cm) piece of cable trunking to reinforce the limbs.
8. The limbs are made by warming up the PVC pipe and cable trunking, then inserting the trunking into the pipe.
9. The author used a piece of laminated flooring and a clamp to straighten and shape the limbs.
10. The handle is made by heating and shaping a PVC pipe.
11. The author used a profiled rigid handle to prevent the handle from diverting the arrow.
12. The arrow rest is made from a piece of pipe and three toothbrushes.
13. The string is made by spooling a cord onto a reeling frame and then tying the ends together.
14. The author used a Blood Knot with back winding to secure the string.
15. The serving on the string is made by winding a cord around the string and securing it with a self-tightening knot.
16. The author used a soft stopper on the reeling frame to facilitate winding.
17. The bow is camouflaged with Europe Autumn camouflage fabric.
18. The author plans to impregnate the bow with a polymeric compound to make a composite bow.
