Cutting through dovetails doesn't get much simpler than with this 15" jig. There's very little setup, and only slight adjustments the first time you use it.

You also can cut dovetails for angled joints with this jig. Buy the optional small-bit set ($69) to create scaled-down through dovetails, or the box-joint bit ($34) for traditional box joints—both with the same Journeyman template as you have it set up. The only downside to this jig is that it won't cut half-blind dovetails.
