Yee Haa I am hijacking this thread!! Sorry in advance. Toomanyknots DID NOT ASK IF YOU WOULD MAKE A BOW OR TRAP! He asked how long you think it would take to make a serviceable bow. In my opinion this is dependent on whether I have some tools or not. If I had to use stones as tools it would take me a long time. If I had a small knife and ideally an axe or maybe just some hacking type of knife it would simplify things thus speeding it up considerably.
My scenario: the shit has hit the fan, and it is a survival situation, I have a knife and a small axe. I live in the countryside in Germany, it is let us say spring or summer, living outside or in a camp is doable. I would look for elm, ash or hazel saplings. Black locust does grow here but I think that would be making things harder for me than necessary and I do have elm here so I would go for that. I would cut several as to give myself some choice and expecting breakage. I would also cut hazel shoots for arrows - as many as possible. With an axe and knife I think it is possible to cut and roughly shape let us say four bows. No chasing rings, bark stripped off back of bow finished! In a day. Sounds like I am wasting time but no. They should be dried as much as possible so over a fire along with the arrow shoots whilst doing this you should start making birch resin, you will need this to help sticking any sharp bits of stone on the end of the arrows - (I can't nap)
Mike says cordage is the problem - yes and no. If you have clothes you have cordage, if you find someone dead then their jeans will be cordage. You have to be a pragmatic badass to survive. Elm and nettles and ash bark will make cordage I have not tried this but do think I could manage it would put an extra day on the process though. So, I think I could make a bow and arrows in about 2 days. I would having achieved this and hopefully having a full belly have some time to carry on making a better stronger bow and more arrows. In a survival situation with possibly hostile people (hope to god no one has a gun) having a bow and arrow could be the only thing stopping someone using your clothes for a bow string.
2 -3 days wouldn't be my best bow, or maybe it would LOL
Hope I haven't upset anyone the Prignitzer bowman
