The first Beech bow I made about 15 years ago was fairly short, maybe 62" long, 1 1/4" wide limbs. I tillered the bow to 28" and it pulled about 50#. I still have that bow, not much to look at. It did not chrysal nor did it explode so I don't think the wood is brittle at all. I have heard some say that the European species of Beech is brittle though, can't comment on that one as I've never used it.
