I've only worked one piece of BL, and even though that is coming out a flatbow 80-100#, it feels like it manage a longbow design up to 150# maybe more.

thanks for letting me know, i actually have some i am going to be cutting soon to start drying, Ian bl in this case im pretty sure does mean black locust. the one i think i will be using is around 15inches across and has some nice sized rings. when i do use it, should  leave some sapwood for a back, because i know the heartwood is very good in compression but im not sure about tension
thanks ;D

nidrinr:
yep, black locust.

Pat B:
Black locust has good tensil strength.  I have left a few rings of sapwood on locust bows but I knew it was sound and they were in the 50# to 60# range, not 150#.

so if i were to attempt even a 100 bow with bl, should i just go very wide and long? i really don't feel like pulling wood out of my arm, and is it good if the rings are thick, as the tree i might be using i have a cross section cut out because we needed to know when it was planted for something, but the rings i am thinking of using are around 1/4 thick, the thing that confuses me is that on the cross section we cut, the center with the 1/4 in rings split out almost completely from the rest, and after the split the rings are only like 1/8-1/16, what could have caused this, or was it just a coincidence
thanks
noel
