The inside surfaces of the pieces are the reference surfaces because they, not the outsides, will contact their mating pieces. So, they should be flat, free of any winding (twist), and cleaned up enough that any final touch up just before assembly will not substantially change their trueness.

Here I’m working with 5/8″ thick curly red oak, a lovely but somewhat cantankerous beast, about 6″ wide. If you are just starting out, I suggest a tamer species such as straight-grained poplar or perhaps soft maple. Very soft or “stringy” species such as cedar are actually more difficult to work because the fibers tend to crush when fitting the joint. woodworking tips and techniques woodworking woodworking tips and tricks for beginners
