If you have a table saw why not mill all the strips to the same thickness before gluing up? And after that the smaller panels to fit the planer seems to make sense given what you have on hand. The rotex is also great for this but its not really ideal if there is a more appropriate solution (strips the same width, and a proper planing solution). I love this "right tool for the job" thing, there are about 10 different ways to do this that are not wrong and have all been used effectively in the past. How is the RS2 the "right tool" for (face)jointing panels?
