Jack, You are making this too complicated for yourself. The front and back have to be a mirror. Because you want to put dado on the backside not the front. If you notice on mine, the top and bottom shelves are the key to holding it together. All you have to do, is trace the inside 3/4 using part works and the deeper the better for your dado. As for mortice tendon, you will end having a lip. The bend, after you get your bottom and bottom assembled can be done with 1/2 MDF. It would probably be better to use 3/8. If you are worried about trying to clamp this thing, just try to sneak in some brads. If the bend is too strong, you can always use ratchet tie downs if the brads start popping out. I think it is probably better to make this out MDF except for the top, bottom and shelves. You definetely want to screw in the top and bottom because they will be your anchor and make sure you use plywood. The reason for MDF, I think it looks better with a large round over; I would make this unit 7' tall. Sure Jack you can make it more complicated but sometimes we over engineer for nothing. You can put one of these together in a day. I want to put one in the showroom. The Bot really shines on one of these projects. Without the Bot, a project like this would be huge. Remember KISS keep it simple stupid. I follow that philosophy because if you look at my stuff I have a very simple formula. For Dave, nice photo I wish I had more adventurous clients to try stuff like that. I'm in danger of my stuff looking all the same. Kevin
