Hi,
I am making a bead on an apron with a curve on the underside. I am getting som tear out in one end of my test piece no matter what way I am going. Any suggestions to avoid this? I am trying to have a low pressure on the tool.
I am using a LN no 66.
thank tiu

Your test piece has a knot on the other side of the bead. Knots can cause some changes all the way across a board. The ends of boards also frequently are difficult to work and are places I always have to do some work with a scraper to even out. It's a good idea not to cut to length until the bead is done, so you can just saw off the uneven end.
Hi,
Thank you for the answer.
I have the same problem with another piece without a knot. Good idea to cut to length after, I will do that next time🙂
Try going the opposite direction. Even though its set up as a scraper, it can happen.
As I wrote, it happens either direction I am scrabing
The ends of the board provide less support for the tool, and this ends up with it dipping, which causes uneven cutting.
Two factors reduce tearout: The first is the commonly-recommended comment of a sharp edge. As sharp as you can get it! The seconds is to take very light strokes until the outside edges are well formed. In fact, you could also use a cutting gauge to score the outer boundary line.
Several years I developed a method for reducing tearout using a plough plane, such as the Veritas Small Plow. It was surprised that no one had thought of this. Quite simply, add a 15-20 degree back bevel to the blade to increase the cutting angle. http://www.inthewoodshop.com/ToolReviews/VeritasSmallPlowasaBeadingPlane.html
