Building a credenza with 3/4” plywood. Using miter joints on the carcass to avoid showing the plywood “end grain”. How can I reinforce those joints? The pros are using festool domino. I have a handheld drill and a handheld router. Can I do a dowel joint? I don’t know how to do that on a miter.
If you want to add some visual interest you can do a visible dowel key by buying or making a jig like this one.
Or if you want to keep them hidden you can make a doweling jig like this one.
