Here's an idea for a new product - pre-cut dovetails. Two long strips of wood (8' lengths, like molding) with the tails and pins already cut by a machine. Measure how much you need (e.g. 6") and cut that off. Each strip already has biscuit slots cut. Cut biscuit slots in your drawer side, and join it with the dovetail strip. Cut biscuit slots in your drawer front, and join it with the pin strip. Done! Sure, you'll have a glue line, but nobody will see it because they're looking at the perfect dovetails!!!
I'll call it E-Z-Tail. Available in all the popular wood species (oak, maple, walnut, cherry). And I'll leave Frank in the dust......
