I am making a Federal Period reproduction of a serpentine sideboard similar to one featured in FWW Magazine by Steve Latta. The two curved doors have crotch mahogany veneer applied to a concave surface. When sanding the crotch veneer how necessary is it to get it really flat? I can feel subtle differences between early wood and late wood and I assume that this is the nature of this veneer species. I am also of course hoping not to sand through the veneer. I just wondered what the prevailing wisdom thinks and also what grits would you recommend to start and finish with? I did make an additional set of doors for practice and found that my 5" random orbit sander is able to negotiate the concave surface. Thank you for any advice that you could provide.
