I should have added that the fence should be tall enough to support the
board and obviously (or maybe not) has to be long enough to support the
board completely on both sides of the index pin. I was so caught up in
showing the relationship of the fence, the angled support block and the
index pin that I neglected to scale the height and length of the fence
appropriately. ;~)
