L\ <- the "\" would be the circle portion, http://www.clickdensity.com/images/pie_chart.gif looked likt the red portion of that graph. I screwed it to the subfloor about an inch off the ground, placed my boards under it and marked my line, took them out & cut on the jigsaw. Get lots of good blades its pretty tough stuff.

It is routable, I didnt route it because it seemed to risky that the router may kick on me and then I would have some board repairs to do with glued down flooring.

Beautiful workmanship, you're hired.
