Bob B. (Missouri),Hi Bob, I believe Charlie aslo usued yellow cedar for rib construction, although it is a little heavier. I personally purchased spar grade sitka spuce( approx. 6 X 16' ) that had a longditudinal crack in one end. This was purchased at a much reduced price but I was able to work around the crack, cut all my material from the one piece and saved a lot of money, but I know what I have is # 1 ribs.You may also purchase 2nd grade sitka for rib construction as long as your spars, Longerons and diagonals are #1 Grade sitka or other acceptible alternates.Regards,Domenico Bellissimo________________________________________________________________________________
