Now that the dado in the horizontal piece is complete put it temporarily in place over the vertical piece. The joint should be snug but neither loose or tight.
Score the lines for cutting the curves on the vertical piece.
You can see here the score lines ready to begin cutting.
Repeat all the steps shown in earlier installments of the blog to create a dado in this piece that is 1/2 the depth of the lumber, etc. Here you see both pieces with the waste removed. They are ready to glue together in the next blog.
