well i wont say it wont make a bow.
i dont own any books on bowmaking or what woods are better than others.i have read more than once that any wood wil make a bow but some excel at it others dont.
however i have a made several bows and know that only experience is the key to working wood into a bow.
now i am not real sure what 1.4m is,i am thinking that comes out to about 4.5 ft.kinda short for a slefbow.
however it will make for good practice and give you a good idea what the wood is capable of.
so if its 4.5 ft,then .1m diameter should be about 4 inches.
i would remove all bark and cambium,then i would rough shape it into a bow and let it dry for a few weeks before going any further.
while drying after it has been roughed out,you may want to clamp it down to prevent warping/twisting.
after a few weeks of drying,if it makes a ringing type noise when tapped on the concrete or hard floor it should be good to go.
i would then proceed to make a bend thru the handle bow, or a "d" bow as they are refered to.
should be able to get a 26" draaw from it if you ae carefull,not sure what kind of weight.like i said i have never used that wood.
i say go for it and while your making that one you can always look for more suitible woods to use.
good luck and ask as many questions as you would like and as always post pics of the stave/bow as you are building it.especially when asking questions.
makes it much much easier to get the proper answers.you have access to some the best slefbow makers in the world on this web site. so use it to your advantage.
good luck
peace,
