emergency arrow making

[Timelord]

Would it not be possible to make expedient arrows from alternative sources? For example off the top of my head - what about lengths of brake pipe from vehicles. It would have a good weight, might not need a separate head and flights could easily be fitted to a slot cut in the back for expedient quick measure. They can be easily bent "straight" and even fire hardened/tempered by quick immersion. The fact they might bend on impact is not an issue. Thy could be re-bent straight again for reuse. Brake pipe is common in our environment. There will be many other straight lengths of material that could be used if one stops to think about it. "The sky's the limit". lol. TL.
