I am in the process of designing a window box and I want to use Sliding dovetails in its construction. A little bit about the project. I am using an upper & lower rail with a sliding dovetail slot in each of them to receive the outside panels. Each panel needs to connected with sliding dovetail joinery on the left and right edges but I want to also add a sliding dovetail pin on the top and bottom edges as well. My problem is that the geometry for this joint obstructs each other and I am wondering how to go about making the geometry work. I know how to do it with the wood but sketchup is proving difficult.
I hope that I have explained this clearly enough, TIA
