Id like plans emailed to creeper0629@gnail.com.i made a bow for one today but i messed up.it was to stiff and snaped the thick broom handle core like a tooth pick on stringing.didnt get to draw it.have no clue what the poundage was but i could barely flex it to string it.i want a stout bow as i plan to hunt with this.its a part of my improvised survival gear training im puting myself through.you never know when it can come in handy.id like to be able to take large game at 40+ yards acurately.im guessing 100+ pound bow at least.i have ideas for trigers but id like to simplify this as much as possible
