I understand your frustration Mike. I too had struggled for some time as to how I was going to do it. For me the easy way was to do the 1 inch round-over of the walnut pieces against a fence on a router table. It's not only easier, but a lot safer too! Then I cut a relief groove on the underside of them just like on a piece of hardwood flooring. This ensures a tight fit against the edge of the veneer. I then glued and screwed them from the inside of the box AFTER the veneer was applied. I let them overlap the veneer face by just a hair. Just so you can barely feel it with your fingertips. Then carefully use a cabinet scraper to blend the solid edge pieces flush with the face of the veneer. Piece of cake!
If you want a router table cheap I'm only a couple of hours southwest of you in northern Virginia. PM me if you want any more info. Be happy to help in any way.
