    Router as "profile enlarger"

    Not really a jig or a fixture but, a jig-like method to solve a problem. We've probably all seen this somewhere and some folks even sell router bit "sets" to do this.

    Setup the bit of your choice to take an 1/8" bite and set the height to use the existing edge path as a guide. Make your first pass.

    Change to a flush bit (or change bearings), flip the piece and use the "new" edge as a reference for the flush cut. Pardon the burn marks, they get taken care of by the flush pass.

    I did it twice as I needed to increase the dimension by 1/4" and didn't want to splinter the ash with a big bite. Here's the 'after':
