Thanks Pat.
But, I don`t think 100 shots is enough to be called a "good bow".
I mean, a well tillerd bow should last a life time or at least a few years, am I right?
If I want to start making bows for other people, I need to make them durable. Can I call a bow a good quality bow if
the belly frets even after a 1000 shots?
So, how do you know your bows are good?
In my opinion, if you're wondering about this, you are by no means ready to start making bows for other people. A bow that breaks can seriously harm people.
A bow that hasn't broken or chrysalled after 100 shots fired, will not suddenly start fretting after 1000 shots, 24,964 shots or by the first full moon in October. A bow can still break after surviving a long time of shooting, but that is often the fault of the archer (overdrawing for instance) or by bow's owner (storing a bow in winter near a heater, so the EMC of the wood becomes critically low, making the wood more brittle). A bow that has survived 2000 shots of 'shooting in' is not more durable than a bow that has survived 100 shots of shooting in.
To answer question 1) in the opening post: probably beech. But all the woods you've listed are good candidates for heat or steam bending.
Question 2): how do you define "good quality bow"? Quality has many facets. "Surviving to be shot" is not a quality, but a necessity for a bow.
