ive been trying to make a three peice takedown bow for my nephew,not doing too well.i have broken three sets of limbs so far.i am not using any glass on this bow i have another set gluing right now and may be my last attempt before christmas.i was wondering if anyone has made a kids longbow from a board and if so some demensions or a close start would be helpful.bow has to be about 40 inches long since i already have the string.only has to be about 20lbs at most.any ideas or comments would be helpful.thanks, :confused: greg
