When making plywood shelves, I like to cover the front edge of the shelf with a thin strip of hardwood. Making the strips can be a challenge, though. If the strips are cut between the blade and rip fence, there’s a chance the small piece will kick back. But cutting the strip on the left side of the blade requires adjusting the fence between each cut, introducing possible error.
The method I use is simple and accurate and uses nothing more than a combination square, a hardwood block, and a drill bit.
