Help with screws, nails and bookcases

Hi all,

I am very new and inexperience with wood.

My mother would like a bookcase. I've made a tall thin one before, but my mother would like one to be three shelves high, and 5 or six feet long!

I can use either 3/4 pine boards or 3/4 oak boards (more expensive! but it is my mother... sigh...).

But going for something 5 feet or more long, weighted down with books, I don't know if the wood will hold.

DOes anyone know if i should use screws or nails, (which are stronger) and how long they should be?

Also, how much weight can 3/4 wood hold when it is 5 feet long?

any help is much appreciated.

thank you and take care
Michael

Going 5' long you would need a center divider. 6' you would need two dividers. It's not good to span more than 30" with a shelf. If you put dividers in it you could drill a series of 3/16" holes in the sides and make the shelves adjustable. Then all it would need is 5mm spoon pins to support the shelves. A lot of people use peg board as a pattern to drill the holes.

I would only use headed screws if you could put them where it doesn't show. There are finished screws that have a tiny head you could use, 2" should work fine. It would be stronger than nails but if you use glue to assembly it the nails would be fine.

A few questions. Will this be a wall hung or a cabinet that sits on the floor? What tools do you have...tablesaw...router and bits? Being only 5' or so long, you may only need one center divider.

One devider would work, either lumber will work too. I have made several bookcases, I always cut a dado groove in the sides for the shelves, this will also add support. I have the adjustable dado blade from sears, it is carbide. Be sure to cut a dado in a scrap piece of wood first. I also used drywall screws, predrill your holes for the screw heads, drill em deep enough to put a wood plug over the screw and then sand em flush with a sander. You can buy plug cutters for a frill press and cut plugs to match your lumber.

You can also put a back on the bookcase, 1/4 inch plywood will work, if you don't make the shelves adjustable, you nail through the back into the shelves, this will add strength also.

First I do not believe that "screws, nails and bookcases" belong in the same grouping. I would use NO nails or screws. Screws would be conditionally OK if used in a manner where they did not show.

Glue has all of the strength that you need.

Cabinetman's questions need answering. I am with Steve on not making one long shelf 5' long. Too much chance of a sag. One or two dividers should be used. Two if there is no back and one would be OK if there is a back.

I also like Steve's idea of making the shelves adjustable. In that case if you go to 72" you need two dividers.

What do you guys think of putting in a 1/2" or 3/4" plywood back, with a dado for additional shelf support?

Generally a 1/4" back is sufficient.
