I appreciate your emphasis on context in each article of this series. I was reminded of it here. I have a vintage(?) PC biscuit joiner that I dearly love. It’s a delight for plywood case work in the way that I work. In edge-to-side joinery, you’re right, it plays a role … as part of a team. I’ve made face frames assembled with biscuits, knowing that the joints are backed up with the face frame to case joinery as well as the case itself. Thanks for the articles.
