I'm building some 3x3x16" long L brackets out of 3/4" plywood. I'm planning on using a simple butt joint with a single rabbet and screws to attach the two pieces together.
The strips are all bowed/warped slightly. About 1/8" over the 16" length.
In my specific case, Without the rabbet, I could just glue, clamp, and screw the two pieces together.
If I try to rabbet the warped plywood, I'm afraid the depth of the rabbet will vary with the warping of the wood and then yielding
Question: How can I rabbet or dado a warped plywood strip such that the depth into the wood is consistent? Convex side up or down? What if there's a veneer/finished side and there's no option to choose which side?
