The wing tip consists of a laminated bow and the two outermost ribs. The tip bow is made from 5 strips of 1/8x1/16 balsa. On the plans Pete has suggested adding some basswood for strength so I used it for the first three laminations then used balsa for the last two. The spars need to be tapered to get the last two ribs to fit in position then the bow can be fitted afterward. Since the the wing is undercambered the tip is curved up in the middle so you have to glue one end first then fit and glue the other end after the first end has dried, gluing it to the trailing edge first seemed easiest.
