I am building a bookcase and attaching the sides to the top and bottom with dominoes. When I routed the dado's for the shelves, one of the sides was upside down. So, if my dado's match, my Domino mortises don't line up and vice versa.
I was wondering if there is anything that I can use to fill in the mortises that is hard enough where I can re-rout them to make them line up?
Thanks,
