Putting the Leigh Jig to work, the pine mock-ups seem to fit with no troubles.

An issue with high speed routing is
the blow out you experience, especially with end-grain. As the dovertails are for strength not visibility, I’m not overly concerned and can make cosmetic repairs later.

Using the same curve from the drawer front jig, I’ve made up a template for the right hand cabinet door but will leave the base and top uncut for now until I have a better idea of what fits where.
