Read the Grain
Jointers are a great tool for straightening an edge or flattening the face of a workpiece. But it’s not unusual to get a cut that’s rough in some areas. Instead of a nice smooth surface, the wood has patches of lifted grain or areas of chipout or tearout.
In some cases, this may be caused by dull knives or working with highly figured woods that are difficult to joint smooth no matter what you do. But most often the problem is the result of the orientation of the grain in the workpiece.
If there’s a V-shaped surface grain present, it’s tempting to look at the face of the workpiece and then feed the board into the jointer with the V-shaped grain pointing away from the knives. But you’ll actually get a better picture of grain direction if you take a look at the edge.
In a similar manner to edge jointing, you’ll want to check out the edge to see if the grain is rising or falling. But this time you’ll want to feed the board into the jointer in the direction that keeps the knives cutting with the grain direction visible on the edge of the board. You’ll find these same principles apply when you use your planer.
CHANGING GRAIN DIRECTION
Determining grain direction is the best way to get better results with your jointer. The nice thing is it only takes you a few extra seconds, but it’ll save you a lot of sanding time in the long run.
Have a nice weekend,
