I am building a bookcase for my wife. I am using a frame and panel construction and this is he first time I have tried this and I am stumped on a few details.
First let me decscribe the case. 74 tall 38 wide and 13 deep. The actual carcase is 68 inches that sits on a 6 inch base.Made of Pecan. I have a lower stationary shelf at 20inches tall with 2 drawers underneath…which leads me to my first question: The sides are the Frame and panel( 3 to be exact) I left the deviding rail extra wide so I could run a dado through it without compromising the strength of the cbinet. Am I correct in thinking that it can be dadoes like a normal cabinet with a plywood side? If not..how does one attach the bottoms, mid and top shelfs. I sort of want to see the inside panels for inside the case.
#2. The case is 38 inches wide. I have a piece of 1/4 inch pecan for the back, but do you think that 38 inches will be strong enough to hold thecase rigid. I would love to find a way to stiffen up the back to help really STIFFEN up the whole case for moving and such. Or is frame and panel stronger than I give it credit for. I am using mortice and tenon construction with 1 inch tenons. This will be a hand- me- down peice so I want to build it for generations to come.
So to clarify question 2: can I use just the sheet of 1/4 pecan set into rabbets like normal. Will that provide enough rigidity for frame and panel sides?
I have very selective in my lumber and so far this piece looks great. I have worked pecan before with a chest of drawers and it still looks good after 15 years. I am excited.
Please give me all your experience and advice please!
thank you

If I were building this piece I would make my frame and panel sides all one piece. That would be the proper and most normal way to construct it. Plan your panel rails to conincide with where you want your shelf dadoes. Although from your description it sounds like you've already made your frame and panel sides. Dadoing the shelves will be ok to do, but have you considered making this a stackable unit, with the shelves rabetted into the tops and bottoms of each frame and panel? You could stack them just using loose dowels. Makes moving much easier.
To address your other question, again, if this were my piece ,I would put a stretcher across the top rear ,at least three inches wide to help stiffen the cabinet. I would attach it on the inside of the cabinet using pocket hole screws( on the rear of the stretcher, so the screws aren't showing from the front) using of course a matching piece of pecan. If you don't have a pocket hole jig you can always screw from the outside and use plugs to cover screw holes or nail and glue from the outside. The strecher not only gives the cabinet rigidity but you can also be used it to fasten through to the wall so it won't tip over if a youngster tries to climb on it.
That is what I have done. I built both sides as a unit. Each side is a unit 68 inches tall. After I shape the panels they will be ready for glue up. The face frame is glued up all ready. I just need to make my bottom for the drawers, stationary shelf out of a glued up pecan and another top of plywood. I planned my middle rail of the sides so that the stationary shelf above drawers can slip into a dado in that rail.
I think i m ok in my thinking since you are concurring with my thoughts. I agree about the back support.
I am traveling now so when i get home I will add a sketch for you to look at. I hate to bother you so much but i dont want to get too far into this and realize that I have screwed up 300 dollars worth of lumber.
thanks for the help
Actually if your face frame is substantial, you really don't need a stretcher across the top back . Your 1/4" panel should be suffient, unless you want the extra support and a piece for fastening to the wall. If your fixed shelf is made from glued up boards of solid pecan then remember to only fasten the shelf in the center on each side to allow for normal wood movement due to humidity changes, or from the back only as another poster has suggested, otherwise your selves will crack over time. I built my kitchen cabinets from Hickory/Pecan many years ago when Hickory wasn't popular yet and it is a hard , hard, wood . Has held up very well over the years.

I make a frame and panel style of back. If you use just a plywood panel for the back, set it rabbets let into the sides. Install with nails and glue.
I use a frame and panel construction for all of the chest of drawers I build. Yep, you can dado for shelves, as long as it is not along a plywood panel. I set a plywood back into the back of the case's sides. Of course, with a chest of drawers, I can nail into the web-frames the my drawers slide on. If thier is a fixed shelf on your project, fasten the back there.
