I would get the bark off now if it was me ,it should peel like paper for you I shellac the back & ends right away , if your in a hurry for a bow let one set in side for about 2 weeks & then ruff a bow out & let it set inside 50 % RH for 2 months & you should be good to go ,in the first couple of weeks hickory loses a lot of moister I made one inside of 2 months off the stump but wished I had waited longer but I was like you in a hurry for a bow , others might have some other thoughts but that has worked for me , do you have a food scale you can weigh the stave while it's drying and when it stops losing weight for a couple of weeks it should be acclimated to your area,hickory can take a fair amount of set if worked to soon , keep us posted on how it goes for you !
