Chris and Chris worked on the wing tip jig with a sander. Finally got it good enough to use. Some areas needed shims. Bro Chris when and picked up .05 aluminium to use as the shim between the tabletop and the rib and also bought ABS adhesive. Bro Chris worked on cutting out the aluminium shim. At the end of the day, we took the bold step and glued the rib and tip together weighing down the rib and the rip with sand bags......will know how it looks tomorrow.
