beech has a specific gravity of about .64, which is actually higher than the specific gravity of vine maple, which is listed as .60. im sure it would make a decent bow. i dont have any experience using it but im sure if you treat it with care it will turn out well. slight overbuilding would help until you figured out what dimensions the wood likes best if you plan on possibly using it alot with successful results from your first. good luck and post what you get out of it, id definitly be interested in seeing how it turns out.
