More specifically even, its specific gravity, but species itself will get you close. When in doubt, go wide. If you tell me what species elm, how long you want the bow to be, and what poundage you want I will tell you exactly how wide to make it.

Not trying to hijack the topic.
I have Winged elm, can you give me that information ? 45 to 50 lb. I would make my bow 64" to 68" NTN :)

No problem. You need 44 sq inches of working limb per limb.
So a bow limb thats 2 inches wide for 15 inches then tapers to 1 inch over a 10 inch length will give you what you need. That will allow for handle and stiff tip length. That will give you 45 sq inches of working limb. The tiller should bend in an even circle and I believe a tiller gizmo tool by Eric on here will give you that perfect bend. Heat treat elm deeply and to a darker color to get the most out of elm. With proper heat treat and tiller, this should government you a 50 pound bow that takes no more than .24l5 to .5 inches set with that range being based on the wide range of density winged elm can have.
