Dealing with wood defects

Cup: A board that rocks
from edge to edge
when laid on one face.

Cup Defect

Solution: Rip a wide, cupped board into narrow flat sections, as shown in Photo B, below right. Rip each piece slightly wider than you need, then re-rip or joint the edges square to the face. You even can glue these sections back together to create a wide board.

Rip cupped boards with
the convex face against
the saw table. A scrap
clamped to the fence
guides the workpiece
and holds the portion
being cut flatly against
the table.

Transform mildly cupped lumber into flat, thinner boards. First, joint the concave face flat, then plane the other face parallel.

I had a few pieces of Oak that were crooked and my solution, due to limited space and tools, was to align and clamp the board with the outside crook parallel to the edge of my workbench then use a HD trim bit in my router to straighten the crook. Then I ran the routed edge through my joiner and finally used this straight edge to guide the board through my table saw to trim the inside crook off for a nice straight board.

There is nothing wrong with knots. Knots and the grain around them add character and color to the wood. Small knots can be glued in place with super glue, larger ones with gorilla glue before processing the wood.

The other day, I needed to clean up rough edges on 4' boards. Rather than use a carrier strip requiring extra steps to install/remove double-sided tape, I clamped an 8' length of 2"x2" angle aluminum onto my fence over a 1/4" spacer to lift it off the table saw slightly. This gave me an 8' long fence that the rough boards could ride against... a charm. Quick work of all the boards -- even with resetting the fence position for different board widths.
