Topic tags/keywords: question white pine

I need to build a fairly large bookcase, and since I’m in Maine, most of the locally available wood is white pine. I was thinking of stopped dadoes for the shelves. Anyone have any idea how wide of a shelf I could get away with using white pine 1×10? and would another type of joinery be better? My wife and I are both grad students so the books are piling up quickly.

Check out the sagulator

You might want to make it out of plywood.

Shelf pins give you some flexibility.

Make one shelf fixed and the others moveable for more flexibility.

The major advantage of fixed shelves is the fact that the deflection, according to “Understanding Wood” book, it 5 times smaller than with adjustable shelves. I got 4” span on 5 1/2” wide shelves for some of my bookshelves. They have no visible deflection when loaded with books.

I am not sure if the sagulator gizmodyne pointed you out to computes the deflection for fixed or adjustable shelves but based on my numbers, you should easily get away with 4” span on 3/4” material. The pine is more rigid than plywoods though. Also, pine is only about 20-30% less rigid than popular hardwoods like cherry and oak (this is why it is a good construction material).

I hope his helps,

I built this one last winter using 1×10 pine. It is 6 feet tall by 3 feet wide, I used blind dadoes but to prevent deflection I made the back from 3/4 pine and cut rebates to accept the back edge of the shelves. This provides support along 3 edges. No deflection to this point and it is heavily loaded all the time.
