Wingtip alteration, modified to hoener style carbon fibre tips. tips sourced from a well known cub clone kit supplier, good fit to the rib profile. I added a plywood rib to the last full size rib. An Al angle was formed to the rib profile, nutplates were rivited to attach the wingtips, the Al angle was attached with #4x3/8” round head wood screws to the plywood rib. Not shown in the pics is large lightening holes in the plywood rib. If I did it again I wood eliminate the last rib and just use the plywood rib as the final rib.
Too late smart.
