Selecting Lumber for Best Results

3 days ago
We all know to avoid lumber with large, loose knots, and twisted, warped, split, cupped or checked lumber... but how do you tell which boards will most likely do those bad things AFTER you buy them and use them? Here are some photos to show you what to look for and what to avoid. The pieces on the left are desirable and those on the right side of the photos are to be avoided. This is based on how wood behaves depending on ring shape, density and orientation. The last photo shows you what the pith looks like on the face rather than end of the board.

      Jon.murphy The more rings the stronger wood you get, the closer to the grain the poorer quality your timber is.

    I read an article recently which stated using the diagonal grain for the legs of a side table.

    The text shown on this pin is ridiculous. What it is actually showing is flat sawn wood on the left and rift sawn wood on the right. There is no structural difference between the two however there are functional differences when used for wood working

    I read the same article and that angled grain was desirable for turned table legs in order to get a consistent pattern all the way around the leg
