The more ive been thinking about this and talking w/ some people - I think i may have come across an easier solution.
Before I lay the floor - make 14 "blanks" and do the inlays in the blanks. The blanks will consist of 3 stips of the hardwood floor boards (4" wide each) glued together and cut to 12" lenghths.
Then do the inlay in the blank. Then lay the blank in the floor when the appropriate row is laid. that way if I make a mistake w/ the router - its just the blank that gets hurt - instead of the entire floor.
My concern is the movement of the floor w/ the humidity and how the glue will hold up.
Any comments on this?
Thanks
