Greetings from CT: I'm seeking advice on preparing a pau ferro fingerboard blank prior to beginning the rough shaping. My plan was to start the EUB project this summer, but I wanted to seek the advice of those who work with this sort of thing on a regular basis. The pau ferro fingerboard blank (4.125 x 1.06 x 36+") has been around for 18+ months. The ends of the board are still waxed. There is a some bowing: <.044" deviation measured under a straight edge where there is a bit of grain runout on the edges. Would you give it more time to see if there is any additional shrinkage before flattening the faces? Trim the ends off first? Once I start removing material, would you recommend allowing extra time between steps to monitor movement? Any bits of advice are greatly appreciated!
