What kind of glue are you using?Are you done heating? If hide glue , it cures fairly quick. I tillered a cherry bow (pics soon)after a day and half.If the glue is hard ,not jelly , it should be good. (depending on drying conditions, and method of application) You just don't want to heat after backing. Backing can affect the tiller , so I do it first. Every one is different, just my methods.Good luck!
