Hi Peter, On the plan, notes are quite sparse, but it does list an order of tasks to complete the wings. So I've just followed that and gone ahead with sheeting the underside first, to the rear of the main spar. It went well with no unforeseen problems. What I found a bit unusual with this plan for the wings, is that there aren't any jig tags on any of the ribs. So the only way to ensure the ribs are in the correct position, was to make sure the upper and lower spruce spar, were at 90 degrees to the building board all along the wing span. I managed that by cutting a few pieces of wood with a 1/4" slot and placing them at intervals along the plan. Here's a photo of the sheeting done so far and one of the simple jigs I made to keep the spars perpendicular whilst gluing the ribs in place. Once the glue had dried, it was then a simple matter of adding the 3rd spruce spar at the front, which slotted into every rib easily without any fettling, giving me confidence that the ribs are correct. Would sooner have jig tabs though?


Next on the list was the vertical grain webbing, which all went in place nicely forward of the main spars.
