Swimbill,like the others said,definitely boil or steam,and make sure you clamp a piece of metal strap on the belly before you bend.It may still crack a little,but will hold everything together much better.Also,when preparing to bend,leave the area to be bent about 1/8" thicker than the final thickness,and put a coat of shellac on the area you'll be heating.This way,when it cracks,you can remove the damaged wood,and still have plenty to finish your bow with. God Bless
