Advice for solid wood corner bookcase?
I've built coffee and side tables out of solid wood, and I've built a bookcase out of oak plywood: For my next challenge/home project, I'm designing an all-wood (no ply) corner bookcase (30 inches to a side, 10 inches deep, 74 inches tall). And I was hoping to get your advice.
Here are a few screenshots of my SketchUp model...i have it half and half right now, between two styles.
On the left, the front is basically one length of cherry with a LOT of cutouts for the stained glass bays and the windowed display at the bottom, and then the back has reinforcing strips down the sides and across the grain in between the panels.
On the right (which was my original thought), it's basically a large frame-and-stile design, with two 3-inch strips glued together for a 3x1.5 inch beam on each side, with other 3-inch strips going between each stained glass bay (pay no attention to the decorative striping, although that would disguise the glueline).
Basically, at this point I'm looking for feedback on which design would be best (or another design I haven't thought of). As far as I can see, the advantage of the first design is that (almost) all the grain would be going basically the same way...the sides, top, bottom, and shelves would all be expanding/contracting in the same direction, instead of pinching or stretching in every which way. And even though the halves are at 90 degrees to each other, it seems that they would just expand/contract independently of each other without messing each other up (although as I've never worked with wood movement on this large a scale, that could be completely wrong). Whereas the advantage of the second design is that I don't need two huge cherry boards that will just get hollowed out anyway, and the wood movement along the frame would likely be minuscule and easy enough to account for with the shelves and top (although again, I could be wrong).
So...any thoughts or advice? Am I doing this completely wrong and need to start from scratch? Any and all feedback will be appreciated. What can I do to make this project structurally sound?
