Got to work on the upper wing-tips tonight. The series of photos shows the progress from marking the balsa from the patterns, rough cutting with a coping saw and sanding to the right shape. Twas then I noticed the wing-tips were 1/8th inch too thin, so I had to cut two blanks from a sheet of 1/8" balsa, glue it on (to the bottom) and sand a bit. Last photo shows the wing tips attached to the wing. Will let them dry overnight, then sand to shape on the morrow.
Thanks for looking in...
