Welcome to PA , plastic_jesus hour bow is in that stave all you have to do now is get rid of all the wood that isn't your bow, but make sure you don't get rid of any wood that is your bow. I know you don't want to screw up but if you do which most people do, don't let that stop you figure out what went wrong and start another. I think one of the best things a new bowyer can do is harvest some wood, as much as you can so you can have a good supply of dry cured staves. I'm assuming your stave probably isn't dry yet if you just harvested it. If you removed bark and let it to dry you should probably put something on it for sealer like shellac. You need to apply where bark was "back of stave" and ends of stave or you will get drying checks "cracks" that could ruin your stave. Don't put any on "belly" split side of stave so moisture can slowly escape from there. You can speed the drying process some by "roughing out bow" to a "heavy floor tiller" just so it's starting to bend. You don't want to bend you stave much till it properly dries. Good Luck
PS for me this site and you tube videos where a tremendous help
