Last weekend I routed the bead and cove in my WR cedar strips. About 40% come out perfect, about 30% are fit for use and the other 30% I endded up trashing. I keep the strips grouped by the boards they came from and it seems that some of them simply won't machine without splintering. Mostly when working the cove, but quite a few splinter when machining the bead. I'm using a 1/4" router with matching bead a cove bits (about 1 1/2" diameter). When I run into a stubborn set of strips I've tried different speeds, turning the strips around and running various feed and router speeds but nothing seems to help. This is my second campaign of making strips.

I also did some pine strips and got close to 100% yield.

Any ideas for improving my cedar strips? What kind of yields are other people getting with cedar? If anyone has purchased strips, are they all perfect?
