BL = N*L

The board length is the minimum length of material you will need to cut the segments for that ring.

To find the board length multiply the length of the segment by the number of segments in that ring. (N*L)

In this example it would be 24*1.256 or 30.144.

To compensate for the width of the sawblade, I usually add an additional two or three inches to each board so I have plenty left over after cutting each segment.

«Be aware that BL is the minimum board length from which these segments can be cut. Make your board longer so you can trim cracks off the ends, cut around knots or other imperfections, cut extra segments or simply make a mistake or two☺.»
