Not sure how to explain this, so bear with me. I was admiring a walnut letter tray on abpw and wood like to make one with the sides sloping outward and with dovetails cut on an Incra. Is that possible? I don't understand the geometry of dovetails that intimately to visualize if it is doable. The picture of the letter tray appears to depict sloping sides with box joints. If that's the only practical way to do it, then that would be fine too.
Please cut me some slack if I'm not explaining my question adequately, as I don't always know the proper terms.
