Texture alignment

I am having trouble with wood-grain textures in assembling things like table tops, bookshelves, etc. The side and the end of the object always lines up 90 deg. from the top. I have tried assigning the texture (image) to individual faces, but it always ends up with the same orientation. Please help. Thanks, George:spin:

In material buttons, map input tap you need to switch Orco to UV and unwrap it

Orco is just the default procedural way of applying a texture and needs a little tweaking sometimes, but in this case it would be easiest to just unwrap it
